Product Description

Product Description

 

 

Features:

* Stability indicator automatically shows current measurement status.

* Auto-Hold function freezes stable reading for easy viewing and recording.

* Automatic electrode diagnosis shows offset and electrode slope.

* Reset feature automatically resumes parameters back to factory default options.

* Help message as a operational guide that helps you quickly using the meter(for PH-220).

* Manual temperature calibration improves the measurement accuracy of meter(for PH-320).

* Selectable temperature unit (°C or°F ) meets different application requirements(for PH-320).

 

pH Mode (For PH-221/320):

* 1 to 5 points push-button calibration with auto-buffer recognition.

* Automatic electrode slope display helps user decide whether to replace sensor.

* Automatic Temperature Compensation provides accurate measured values.

* Calibration Due Reminder prompts you to calibrate the meter regularly.

 

ORP Mode(For PH-221/320):

* 1 point offset calibration allows adjusting the displayed value to a known standard.

* Relative and absolute mV measurement modes provide accurate ORP readings.

 

Ion Concentration Mode(For PH-320):

* 2 to 5 points calibration providing the 8 concentration points can be selected.

* Automatically recognize ion electrodes, does not need to specify the type of ion.

* Direct ion concentration readout simplifies the elaborate measurement process.

* Selectable multiple concentration units include the ppm, mg/L and mol/L.
