PHSJ-3F Laboratory pH MeterDetailed product description：

The main features of PHSJ-3F laboratory pH meter are:

Dot matrix backlit LCD display, Chinese operation interface, easy to use, all-round GLP operation standard design, with self diagnostic function
The test results can be stored, deleted, viewed, and printed with functions such as wide range automatic temperature compensation, automatic calibration, and automatic calculation of electrode percentage theoretical slope. Up to 50 sets of measurement data can be stored each
Users can choose from five pH buffer solutions for automatic calibration of the instrument
There is an RS-232 interface that can be connected to a TP-16 printer or communicate with a computer using lightning data acquisition software
Users can measure the pH values of ultrapure water, pure water, and boiler water by adjusting the equipotential point and selecting specialized electrodes
