903P

Characteristics:

pH Mode:
1. Multiparameter portable pH/DO meter is equipped with a large backlit LCD display.
2. 1 to 5 points push-button calibration with auto-buffer recognition.
3. Selectable pH buffer standard (USA/NIST/DIN) or using the custom calibration solutions.
4. Automatic electrode slope display helps user decide whether to replace sensor.
ORP Mode:
1. Single point offset calibration allows adjusting the displayed value to a known standard.
2. Relative and absolute millivolts measurement modes provide accurate ORP readings.
Dissolved Oxygen Mode:
1. 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
2. Manual salinity and barometric pressure compensation improve the measurement accuracy.
