pH Meter

Functions and Main Technical Specifications



 3 1/2 digit LED digital display, which can display pH value, mV value, temperature value, high and low limit values of range as well as error mark..

 Stable internal storage memory, parameters and other information will not be lost in case of power off.

 Automatic identification of pH buffer solution, three-point calibration, which improves the measurement accuracy of the instrument.

 With functions of over-limit alarm and control, data setting by touch, setting of relay acting point within all-range, and with a setting of backlash area to protect the relay from too frequent jumping around the setting point.

 Transferable 4-20mA photoelectric isolated output, with transfer values corresponding to high and low limit values, that is, 4mA corresponding to low limit value and 20mA corresponding to high limit value.
