Handheld pH/ORP/Conductivity/TDS/Temperature 5 in 1 Meter,Datalogger,
High accuracy multiparameter water quality meter includes 4 measurement modes, the meter is suitable for measuring the pH, ORP, Conductivity and TDS of the liquids.
pH Mode: • High accuracy portable multiparameter water quality meter is equipped with a large backlit LCD display. • 1 to 5 points push-button calibration with auto-buffer recognition. • Selectable pH buffer standards (USA/NIST/DIN) or using the custom calibration solutions. • Automatic electrode slope display helps user decide whether to replace sensor.
ORP Mode: • Single point offset calibration allows adjusting the displayed value to a known standard. • Relative and absolute millivolt measurement modes provide accurate ORP readings.
Conductivity/TDS/Salinity/Resistivity Mode: • 1 to 5 points push-button calibration with automatic calibration solution recognition. • Selectable cell constants (0.1/1/10), normalization temperatures (20/25°C), TDS conversion factors and linear or pure water compensation mode.
• Automatic Temperature Compensation provides accurate reading over the entire range. • Calibration Due Reminder prompts user to calibrate the meter regularly. • Stability indicator automatically shows current measurement status. • Auto-Hold function freezes stable measured value for easy viewing and recording. • Manual temperature calibration corrects temperature deviation. • Selectable temperature unit (°C or °F) meets different application requirements. • Automatic electrode diagnosis shows zero point offset and slope of the electrode. • Help message as a operational guide that helps you quickly begin using the meter. • System menu allows setting the 12 parameters, including the calibration points, resolutions, stability conditions, measurement units, etc. • Reset feature automatically resumes all parameters back to factory default options. • Expanded memory stores and recalls up to 500 readings. • Built-in real-time clock stamps stored data to meet GLP standard. • Stored data can be transferred into computer by USB communication interface. • Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use the meter smoothly.
