1. White backlight, clearly visible even in the absence of light. LCD display, resistant to temperature up to 90℃ without turning black.

2. During calibration, the slope and zero point errors are displayed, and after calibration, the electrode slope is automatically displayed.

3. The RS-485 interface output offers long range and can simultaneously output (PH,℃) or (mV,℃).

4.HI/LO PH/ORP controller (PH/ Oxidation-reduction controller) PC-201C has adjustable hysteresis time, and the controller host can be set for pH or ORP.

5. Microcomputer, single-chip processing, simultaneously displaying (PH, ℃) or (mV, ℃).

6. The main unit is made in Taiwan, and the electrodes are produced by BJC Company of the United States.
