Industrial gradepH(ORP)measuring and controlling instrument

characteristic

Simplified operation menu settings

Stable memory to ensure that data is not lost due to power off

● Three point calibration from keyboard

●Manual temperature compensation(MTC)

● Independent setting of calibration temperature and process temperature

●Beep alarm function

Adjustable high and low point hysteresis width protection relays will not jump excessively frequently near the set point

AsymmetricpH/ORPinput

Large screen white backlit LCD display with black text on a white background, making it easier to read measurement results, multiple prompts, alarm status, operation, and error messages clearly

●4～20mAIsolation current
