Product details
● Product features
Correction and setting password protection;
Large backlit dot matrix LCD;
Technical parameters can be set on-site using buttons;
High temperature qualitative analysis, high precision; Measurable dissolved oxygen and temperature;
Anti interference circuit design, which can be installed and used on the interference site without losing parameters and calibration data after power failure. It has manual setting/automatic temperature compensation process temperature and calibration temperature. When the temperature electrode is damaged, it can be converted from automatic temperature compensation to manual temperature compensation for online verification of test data;
Multiple output modes (relay, 4-20mA, RS485);
Suitable for industries such as aquaculture, sewage treatment, and chemical engineering;
