Soil Moisture Light PH Meter Suppliers and Manufacturers

Soil Moisture Light PH Meter Supplier Concentration and Factory Types

Suppliers of the Soil Moisture Light PH Meter on this page cluster in a few Chinese provinces, and the listing data confirms three distinct sourcing bases. One verified sensor specialist operates from Henan and lists instrumentation as its main product line, including a soil temperature, moisture, sunlight and pH meter with CE certification, a stated pH range of 0.0–14.0pH, temperature compensation from 0.1°C to 60.0°C, and OEM and ODM support. A Zhejiang-based company concentrates on soil nutrient analyzers, seed testers, chlorophyll meters and other plant-science instruments, with a pH and moisture tester line in the SDT series and a broader TZS series for moisture, salinity and temperature testing.

A third supplier, verified in Jiangsu, is primarily an electronic balance and scale manufacturer that lists pH meters and moisture analyzers among its main products, illustrating that this category attracts adjacent weighing-and-instrument makers rather than only dedicated agronomy firms. Company types also vary: one profile combines manufacturing with trading, while another advertises ODM, OEM and own-brand capabilities. When you broaden your search beyond listed results, identify clusters the same way—look at the "place of origin" attribute on product pages, check whether a company's main-product list centers on testing instruments or on general electronics, and treat combined manufacturers and pure trading companies as structurally different partners to evaluate.

How to Verify Soil Moisture Light PH Meter Suppliers

Start with third-party verification status, because the listings in this category differ sharply. At least one Henan sensor supplier is verified by SGS, and one Jiangsu instrument maker is verified by TÜV Rheinland, while another profile shows no system certification recorded at all. Treat verification badges as a starting signal rather than proof: confirm what scope the certificate covers, whether it applies to the factory or only to the legal entity, and when it was last audited. Product-level certification also matters here. The Henan soil meter carries CE and ISO marks on its product attributes, and a Zhejiang tester lists an ISO9001 quality certificate, so ask which documents the seller can actually produce for your target model.

Next, verify manufacturing capability directly against the category's technical demands. A credible Soil Moisture Light PH Meter supplier should explain electrode or probe construction, since the Henan product explicitly advertises a sensitive probe, and should describe temperature compensation behavior across the stated 0.1°C–60.0°C span. Request calibration solutions, a sample for buffer testing against known pH reference powders, and evidence of repeatability between units. Also check customization depth: both the Henan and Zhejiang listings state customization available, and the Henan profile advertises ODM, OEM and own-brand capacity, but you should confirm in writing who owns the tooling and whether firmware, packaging and branding changes are included in quoted prices before committing to development.

What to Compare Across Soil Moisture Light PH Meter Suppliers

Build a comparison sheet from the attributes the listings actually display, without assuming every supplier shows the same fields. Response speed varies widely here: one Henan profile reports an average response time of about 1.17 hours, while a Zhejiang supplier shows roughly 5.24 hours and a Jiangsu maker about 7.95 hours, so message responsiveness is a legitimate differentiator in this category. Lead time also spans a wide range—the Henan sensor supplier states 15 days, the Zhejiang tester lists delivery in 1–3 days for its SDT model, and one Zhejiang profile shows no lead time recorded—so confirm production versus stock-ship timing for your specific configuration.

Compare MOQ and price bands against your business model. Minimums in the listed products run from 1 to 3 pieces on the entry testers, which suits pilot orders, while the multi-parameter Zhejiang instruments sit in higher price tiers and deserve separate costing. Location matters too: Henan for the sensor-focused meter, Zhejiang for agronomy instrument families, and Jiangsu for a balance-maker that lists pH meters among a broad instrumentation catalog. Check whether establishment year is displayed and ask for it where it is not, since instrument calibration experience correlates with tenure. Finally, compare main-product lists to judge whether a soil meter is a core line or a marginal listing, and note that only some profiles show escrow or system certification—verify those individually.

Common Soil Moisture Light PH Meter Sourcing Risks

The most frequent risk in this category is specification drift between the listing and the delivered unit. The advertised ranges—0.0–14.0pH with compensation to 60°C on one model, or 3–8 pH with 0.2pH accuracy and 1–8 percent moisture at 1 percent accuracy on a Zhejiang tester—are lab-sheet claims. Units can fail at the moisture extreme, read pH buffers inaccurately after shipment, or use a shorter probe than the listed 20.5cm on a comparable 4-in-1 digital meter. Always test samples against buffer solutions and a calibrated reference before mass production, and record the sample's serial number as the approved golden standard.

A second risk cluster involves documentation and structural ambiguity. One Jiangsu profile explicitly shows no system certification, which does not mean the factory is unqualified, but it shifts the burden onto you to request ISO9001 or CE evidence per model. Combined manufacturer-trader profiles, such as the Henan company type listed as "Combined," can obscure who actually produces the meter, so ask for the production entity name and factory address. There are also listing inconsistencies to catch: some product families carry multiple model numbers, like the SDT-60 and SDT-300 or the TZS series spanning a wide price band, so confirm exactly which variant, probe length, packing carton size and origin province your purchase order covers, and lock those details into the contract.

Soil Moisture Light PH Meter Regional Sourcing and Logistics

Regional specialization within China shapes both product focus and logistics. The Henan sensor supplier lists 15 days as its lead time, which suggests production-to-order assembly for its CE-certified 4-in-1 meter, so plan accordingly if your launch date is fixed. The Zhejiang agronomy-instrument maker, by contrast, advertises 1–3 day delivery on its SDT pH and moisture tester, indicating stocked standard models, though the same profile records no lead time elsewhere—so verify whether the fast figure applies only to off-the-shelf configurations and not to customized firmware, private labels or multi-parameter variants.

Note the origin fields carefully when arranging freight: the Henan product lists Henan, China as its origin, the Zhejiang testers list Zhejiang, China (Mainland), and Jiangsu suppliers ship from their own base, which affects inland trucking distance to the nearest major port and therefore total landed cost on dense carton-packed instruments. These are compact products—one comparable digital meter lists a body size of roughly 5×3.8×28.5cm at 0.23kg with carton packaging and a 35×8×6cm standard—so most orders ship economically by express or consolidated air freight, with larger multi-instrument orders going by sea. Ask each supplier for the packing carton dimensions, units per carton and gross weight before quoting freight, and confirm whether temperature extremes in transit require protective packaging for the probe and electronics.

Soil Moisture Light PH Meter Commercial Terms and Order Planning

Plan your commercial terms around the low minimums and tiered pricing this category shows. Listed MOQs run as low as 1 to 3 pieces on the entry-level testers, with price bands such as roughly 40.90–45.50 on the Henan 4-in-1 meter and 50.00–55.00 on the Zhejiang SDT tester, while multi-parameter instruments span much wider bands, such as 300.00–500.00 on a TY-3 model and 350.00–1210.00 on the TZS series. Use the low minimums to order samples from two or three shortlisted suppliers, then negotiate tiered pricing against realistic volume, and confirm whether customization is priced separately, since both the Henan and Zhejiang listings mark customization available.

Structure payments and milestones defensively. Where escrow protection is displayed, prefer it for first orders; otherwise use staged payments tied to sample approval, production completion and pre-shipment inspection, and never release final payment before the golden sample is matched against production units. Put the model number—Yy-1033 or Sdt-60, for example—certification claims, pH range, temperature compensation span, probe length, carton packing and stated origin into the purchase order. For repeat orders, lock lead time in writing, since figures range from 1–3 days for stocked Zhejiang testers to 15 days for Henan production, and build buffer stock around the slower cycle. Finally, schedule an annual calibration-check clause with your chosen supplier so pH and moisture accuracy claims remain verifiable across successive batches.
