PH-10/20 Features:
* 2 points push-button calibration with auto-buffer recognition.
* Hold function freezes current measured value for easy viewing and recording.
* Auto-Power Off helps user effectively conserve battery life.
* Replaceable electrode module reduces maintenance and replacement cost.
PH-30/40 Features:
* BNC connector is easy to connect a variety of pH electrodes (Only for PH-40).
* 1 to 3 points calibration with automatic recognition for USA and NIST buffers.
* Automatic temperature compensation ensures accurate readings over the entire range (Only for PH-30); Manual temperature compensation provides a wide range of temperature input (Only for PH-40).
* Auto-Read function senses and locks the measurement endpoint
* Setup menu allows setting the pH buffer set, number of calibration points, temperatureunit, auto-power off, etc.
* Reset function automatically resumes all settings back to the factory defaults.
