Portable dissolved oxygen meter DO-31P 1 piece

DO and BOD measurements in the field. (For BOD measurements, please specify "Main unit only" and "DO electrode for flask OE-470AA".) Energy-saving design The "CAL Memo" function is adopted, which is a sensor with built-in memory to assist with validation. Equipped with interval function, auto hold function, and data memory function (1000 data). Equipped with RS-232C output, analog output, and external printer connection functions. Waterproof structure: IP67, can be immersed in water up to 1m for 30 minutes (excluding when the electrode with stirring function is connected). Measurement method: Diaphragm-type galvanic cell method Measurement range (when using standard diaphragm) (dissolved oxygen): 0 to 20.00 mg/L Measurement range (when using standard diaphragm) (saturation rate): 0 to 200% Measurement range (when using standard diaphragm) (temperature): 0 to 50.0°C Measurement range (when using high concentration diaphragm) (dissolved oxygen): 0 to 50.0 mg/L Measurement range (when using high concentration membrane) (saturation rate) 0 to 500% Measurement range (when using high concentration diaphragm) (temperature) 0 to 50.0°C Body weight: Approx. 280g Can use AA alkaline batteries, rechargeable nickel-metal hydride batteries, or a dedicated AC adapter (optional) Waterproof structure: IP67, can be immersed in water up to 1m for 30 minutes (excluding when the electrode with stirring function is connected.)
