Extech PH/MV/Temp/Cond/TDS/DO Meter DO700

Extech PH/MV/Temp/Cond/TDS/DO Meter DO700. PH/MV/Temp/Cond/TDS/DO Meter. The Extech DO700 portable dissolved oxygen meter has automatic salinity compensation and manual barometric pressure compensation for DO measurements. The waterproof housing meets IP57 standards. The Extech DO700 portable dissolved oxygen meter has one button pH calibration (4, 7 and 10 pH) and a choice of 3 point pH calibration for better accuracy. One point conductivity calibration automatically recognizes 8 calibration solutions. The Extech DO700 portable dissolved oxygen meter has automatic temperature compensation (non-linear compensation for purified water, less than 10µS/cm to improve measuring accuracy). The Extech DO700 portable dissolved oxygen meter's memory stores up to 400 readings with series number, measured value and temperature. The meter has a large blue backlit dual LCD display. The auto power off function saves battery life and also has a disable function. Features: Measures Dissolved Oxygen concentration/saturation, pH, mV, Conductivity, TDS, Salinity, Resistivity and Temperature Automatic salinity compensation and manual barometric pressure compensation for DO measurements One button pH calibration (4, 7, and 10pH) Choice of 3 point pH calibration for better accuracy One point Conductivity calibration - automatically recognizes 8 calibration solutions from USA, Europe and China series Automatic Temperature Compensation (non-linear compensation for purified water <10?S/cm to improve measuring accuracy) Memory stores up to 400 readings with series number, measured value and temperature Large blue backlit dual LCD display Auto power off saves battery life with disable function Waterproof housing Complete with DO probe, pH/mV/Temp electrode, polymer Conductivity cell, pH and Conductivity calbration solutions, batteries and hard carrying case Specifications Dissolved Oxygen Concentration: 0 to 40.00mg/L; Saturation: 0 to 200.0% pH -2.00 to 19.99pH mV -1999 to + 1999mV Conductivity 0.00 to 199.9mS TDS 0 to 100g/L Salinity 0 to 100ppt Resistivity 0 to 100MΩ ⋅ cm Temperature 32 to 212°F (0 to 100°C), pH and mV 32 to 122°F (0 to 50°C), all other ranges Resolution 0.01m/gL, 0.1%, 0.01pH, 1mV, 0.01μS, 0.1° Accuracy ±0.02pH; ±0.15mV; ±1.5%FS; ±1°F/±0.5°C Power Two AA batteries Dimension Meter: 4.7 x 2.6 x 1.2" (120 x 65 x 31mm) Kit: 14 x 10.75 x 3” (355.6 x 273 x 76.2mm) Weight Meter: 6.3oz (180g) Kit: 3.75lbs (1.7kg)
