Import 850081dok Dissolved Oxygen Meter Kit — Buy in wholesale FOB from Supplier in China

The 850081DOK Dissolved Oxygen Meter Kit from Week Technology Ltd. is a dedicated field instrument for measuring dissolved oxygen concentration in water, with applications spanning environmental testing, industrial and municipal wastewater treatment, aquaculture, and fish hatchery operations. The meter displays DO in both percentage saturation and milligrams per litre simultaneously with temperature, using a back-lit screen with selectable °C or °F units. Key performance specifications include a DO range of 0 to 20 mg/L with ±0.4 mg/L accuracy, and an oxygen-in-air range of 0 to 100.0% with ±0.7% accuracy. Temperature measurement spans 0 to 50°C (32 to 122°F) with ±0.8°C accuracy, and resolution is 0.1 across displayed parameters. The unit features automatic temperature compensation plus manual adjustment for salinity and altitude, both of which significantly influence DO solubility readings.

The kit ships with a DO probe incorporating built-in membranes, two spare probe heads, electrolyte solution, instructions, and a 9V battery, all housed in a hard carrying case. Probe heads screw on and off for rapid field replacement without tools, reducing downtime during critical sampling campaigns. The meter chassis measures 177 x 68 x 45 mm and weighs 489 g, while the complete kit dimensions are 279 x 241 x 51 mm. EPA Equivalency Method 360.1 and Alpha Method 2580.1992 compliance is claimed. Importantly, the same hardware platform functions as a pH, ORP, conductivity, TDS, or salinity meter when paired with optional probes from the supplier's accessory range, offering expansion path flexibility for laboratories with evolving analytical requirements.

Single-button calibration to atmospheric air simplifies daily field procedures compared to multi-point calibration protocols. The salinity and altitude manual compensation features are essential for estuarine research, where freshwater-seawater mixing affects oxygen solubility, and for high-altitude lake monitoring where barometric pressure is reduced. Municipal wastewater operators use such instruments to monitor aeration basin efficiency and identify oxygen sag conditions. Aquaculture managers rely on accurate DO measurements to prevent hypoxic stress in intensive rearing systems.

Week Technology Ltd. maintains its registered address at 16 Floor, Building #3, Zhongke Mansion, Shenzhen 518067, Guangdong, China. The supplier is classified under 'imported' tier and 'harbor' trust tier, with a recorded response rate of 0.00 percent and zero average response hours. These communication metrics suggest that prospective buyers may experience delays in quotation and order confirmation, and should budget additional time for follow-up. No ISO certifications, factory audit reports, or export registration numbers appear in the available profile information for this supplier.

The 850081DOK listing represents Week Technology Ltd.'s dedicated dissolved oxygen measurement offering, distinct from their broader multi-parameter water quality meter line. The supplier profile does not indicate year of establishment, production floor area, R&D staff count, annual turnover, or named OEM/ODM clients. Buyers conducting due diligence on Week Technology Ltd. should independently verify business registration through the Shenzhen Municipal Administration for Market Regulation, request a factory visit or third-party inspection, and ask for probe electrode material specifications and membrane lifespan data. The Zhongke Mansion address is a commercial office building, which may indicate trading or light assembly rather than full manufacturing operations.
