Description of the Product
The YR01831 Benchtop DO/BOD Meter is an advanced laboratory instrument designed to provide precise measurements of dissolved oxygen (DO) and biochemical oxygen demand (BOD) in various samples. This innovative device is essential for monitoring water quality in environmental studies, wastewater treatment facilities, and research laboratories.
Equipped with a measurement range of (0-20.00) mg/L (ppm) and (0-200.0) %, the YR01831 model ensures exceptional accuracy with an electrode precision of ±0.10 mg/L and a meter accuracy of ±0.40 mg/L. The instrument boasts a response time of ≤30s at 25ºC, ensuring rapid yet reliable results. It features residual current below 0.1 mg/L, contributing to the overall measurement accuracy.
This meter incorporates automatic temperature compensation within a range of 0 to 45ºC, facilitating precise readings under varying environmental conditions. Moreover, the YR01831 supports salinity compensation from 0 to 45 ppt and pressure compensation between 80 and 105 kPa. Auto calibration through air saturated by water or water saturated by air enhances user convenience and measurement precision. Its polarographic electrode type further ensures the robustness of the readings.
The device is also equipped with a temperature measurement range from 0 to 100ºC, offering a resolution of 0.1ºC. The temperature accuracy is described as ±0.4ºC from 5 to 60ºC, with ±0.8ºC for other ranges. The YR01831’s interface includes a 6.5-inch LED screen for clear data visualization and accommodates data storage for up to 1000 sets. The meter powers on 12V/1A and offers versatile output options via USB, RS232, and Bluetooth connectivity.
