water quality multiparameter tester

Water Quality Multi-parameter Tester

GMP-30 is a unique multi-parameter water quality meter. With 7 in 1 test parameters, it measures: pH, ORP(mV), Conductivity, TDS, Salinity, Resistivity, Temperature(°C).

SKU: GMP-30 Category:

• PH MODE: Up to 5 points push-button calibration with auto-buffer recognition . Selectable pH buffer
Standards(USA, DIN, NIST. Automatically calculates and display electrode slope that help you decide
whether to replace pH electrode. calibration due reminder prompts you to calibration the meter
• ORP MODE : Absolute or Relative mV measurements provides accurate ORP measured value 1 point
offset calibration allows user adjusts displayed to a known standard.
• CONDUCTIVITY /TDS/SALINITY/RESISTIVITY MODE : Up to 5-point push-button calibration allows
user to users customized calibration solutions. Default 10uS, 84uS 1413uS, 12.88mS and 111.8mS)
Adjustable TDS conversion factor ,cell constant ,temperature coefficients and normalization
temperature . (20°C or 25°C) Allows user selects linear or pure water temperature compensation
modes. In salinity measurement modes, Selectable practical salinity (PSU) or seawater measurements
standards. (ppt)
• Selectable either temperature units between degree Celsius (°C) and degree Fahrenheit (°F).
• Automatic temperature Compensation (ATS) ensure high accuracy of measurements..
• Automatic endpoint function freezes the stable measured value for easy reading and recording data.
• Help message as a operational guide to helps you understand how to use meter.
• Setup menu lets users customize the calibration points, stability condition of measurements, temp.
units and date/time to meet personal preference.
• Reset function allows user to return all setting to the factory default value.
• Expanded memory stores and recalls store upto 500 readings.
• Built-in real time clock stamp stored data to meet GLP standards.
• The multi-parameter water quality meter is equipped with an easy-read LCD display that used to show
the measured values and mode icons. The following table describes the function of each icon.
