LEICI PHS-3C precision pH meter, manual temperature compensation

Introduction

Leici PHS-3C precision pH meter is a desktop digital display pH meter. The measurement resolution of both models is 0.01pH and the mV value resolution is 1mV. Among them, the PHS-3CPH meter is manually temperature compensated and equipped with E-201F composite electrode . PHS-3C cannot measure temperature values. This precision pH meter is a pH meter used in laboratories and is widely used in chemical industry, food, scientific research institutions, universities and other fields.

installation method

1. Pull out the electrode base bracket, loosen the nut at the lower end of the electrode bracket, install the PHS-3C precision pH meter electrode bracket to the bottom, and tighten the nut.

2. Install the power supply and plug in the socket.

3. After the PHS-3C precision pH meter is connected to the power supply, you can see that it displays 0mV. Generally, the 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.

Faults and solutions

1. When measuring or calibrating, if the data is inaccurate, you can unplug the electrode and plug in the short-circuit plug. If the number is 0±0.2mV, it means the PHS-3C precision pH meter is normal.

2. If the calibration data is inaccurate, you can press and hold the "Confirm" button for more than 3 seconds in the measurement state. The PHS-3C/3E precision pH meter displays "SYS rSt". After releasing the "Confirm" button, the pH meter flashes. Press the "Confirm" button again, and the PHS-3C precision pH meter will reset the electrode calibration slope.

Precautions for use

1. The PHS-3C precision pH meter is a precision instrument with high input impedance. When in use, keep the input terminal 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-3C precision pH meter and its power supply must be well grounded.

3. During measurement, the electrode lead-in wire should remain stationary.

4. When calibrating, do not mix the wrong solution, otherwise it will cause measurement errors of the PHS-3C precision pH meter.
