PH920 pH/mV/ORP/temp metar
The PH-920 is a high-precision pH meter equipped with a large LCD screen with backlight. The meter can display many helpful prompt messages to help you measure samples quickly and easily.
Specification
During pH mode, up to 5 point calibration at the push of a button with automatic buffer recognition.
Selection of pH buffer standards and temperature units.
Automatically calculates and displays the slope of the electrode after calibration. standard and temperature units.
Automatic temperature compensation (ATC) ensures highly accurate measurements over the entire range.
A mandatory calibration reminder prompts you to calibrate the meter regularly.
During ORP mode, a single point offset calibration allows the user to adjust the displayed value to a known standard.
Measuring absolute or relative voltage gives accurate ORP readings.
The automatic endpoint function freezes stable measured values for easy data reading and recording.
Manual temperature calibration gives the correct temperature value.
Help message as an operating guide to help you understand how to use the meter.
The setup menu allows the user to adjust buffer standards, calibration points, stability conditions, resolution, temperature units, date and time to meet measurement requirements.
The reset feature can restore all settings to factory defaults.
Extended memory stores and recalls up to 500 readings.
The built-in real-time clock stamps stored data in accordance with GLP standards.
Saved data can be transferred to a computer via USB communication.
