LEICI PHS-3E precision pH meter 0.01 level pH value mV (ORP) temperature value

Introduction

The PHS-3E precision PH Meter is a desktop digital display PH meter, both models have a measurement resolution of 0.01pH and a mV value resolution of 1mV.The PHS-3E precision PH Meter is automatically temperature compensated and equipped with E-201F composite electrode and respectivelyE-301F composite electrode.The PHS-3E precision PH Meter measures temperature values. This precision PH Meter is a PH meter used in the laboratory, which is widely used in chemical industry, food, scientific research institutions, colleges and universities and other fields.

Installation method:

1. Unplug the electrode base bracket, unscrew the nut at the lower end of the electrode bracket, and willThe PHS-3C/3E precision pH meter electrode holder is installed to the end and the nut is tightened.

2. Install the power supply and plug it into the socket.

3、After the PHS-3E precision PH Meter is connected to the power supply, you can see that 0mV is displayed, and generally this value does not exceed 0+0.2mV.

4. Install the electrode on the electrode holder, unplug the short-circuit plug, and connect the PH electrode.

Troubleshooting and solutions

1. When measuring or calibrating, if the data is not accurate, you can unplug the electrode and plug it in with a short circuit. If the number is 0±0.2mV, it meansThe PHS-3C/3E precision PH Meter is normal.

2. If the calibration data is not accurate, you can press and hold the "confirm" button on the measurement status for more than 3s.PHS-3C/3E precision PH Meter displays "SYS rSt", release the "Confirm" button, the PH meter flashes, and then press the "Confirm" button.The PHS-3C/3E precision PH Meter calibrates the slope of the reset electrode.

Precautions for use

1、The PHS-3E precision PH Meter is a precision instrument with a high input impedance. When in use, keep the input port dry and clean. When the PH meter is not in use, insert the Q9 short-circuit plug into the socket to prevent moisture and dust.

2、The PHS-3E precision pH meter and its power supply should be well grounded.

3. When measuring, the electrode lead-in line should be kept in a stationary state.

4. When calibrating, the wrong solution should not be matched, otherwise it will be causedThe PHS-3C/3E precision PH Meter is incorrect.
