• One button pH calibration (4, 7, and 10pH)
• Choice of 3 point pH calibration for better accuracy
• One point Conductivity calibration
• Automatic Temperature Compensation (non-linear compensation for purified water <10µS/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
