Compact ORP meter LAQUAtwin ORP-11 1 piece

It is suitable for environmental measurements, factory wastewater treatment, and soil management of rice paddies, etc. The ORP (oxidation-reduction potential) of aqueous solutions can be measured with a small amount of sample. Measurement item: ORP (oxidation-reduction potential) Required sample volume: 0.3mL or more (measurement is possible with 0.05mL if sampling sheet B is used.) Measurement range: -1000 to 1000mV Resolution: 1mV Calibration: 1 point Accuracy: ±2mV (instrument repeatability) Waterproof: Equivalent to IP67. *It will not break down even if it is immersed in water 1m deep for 30 minutes, but it cannot be used to measure total submersion. Display method: Custom (monochrome) digital LCD display (with backlight function) Operating environment: Ambient temperature: 5 to 40°C, relative humidity: 85% or less (but no condensation) Power supply: 2 coin-type lithium batteries 3V (CR2032) Battery life: Approximately 400 hours (when backlight is OFF) *Battery life will be shorter when backlight is ON.
