- Accurate calibration is convenient: it comes with zero calibration and slope calibration functions, supports on-site adjustment of standard solution, easily completes calibration, and ensures measurement accuracy;
- Rich output and alarm: Standard configuration includes 3 sets of photoelectric isolation 4-20mA current output, 3 sets of independent relays, which can freely match monitoring parameters, and flexible setting of high and low limit alarms;
- Stable, reliable, and long-lasting operation: Equipped with a built-in watchdog function, it effectively prevents program abnormalities, ensures continuous and normal operation of the instrument, and adapts to complex working conditions in industrial sites;
Featured Applications
- Chemical industry: The process of circulating water and cooling water through pipes in chemical industrial parks, as well as managing the chemical concentration accurately to stop equipment from corroding and scaling.
- Water supply: circulating water systems in sewage treatment facilities and waterworks; keeping an eye on the quantities of water purification agents to make sure treatment is as effective as possible;
- Pharmaceutical and food production workshops use circulating water to check the concentration of drugs, meet cleanliness and process standards, and more.
- Smelting, the paper mill’s circulating water system, managing chemical concentrations in real time, and lowering the cost of operating and maintaining equipment.

Daily maintenance and precautions
Installation and usage precautions
- Before installing the instrument, it is necessary to cut off the power and choose a dry and non corrosive place. The panel installation should have a 133 × 133mm hole in the control cabinet and be firmly fixed;
- Strictly follow the terminal instructions when wiring, connect the power, output, and sensor circuits separately, and ensure proper grounding to prevent interference;
- The sensor needs to be correctly connected to the power supply and signal line, and the calibration operation should be completed before use to ensure accurate measurement data;
- Regularly check the operation status of the instrument, clean the display screen, and if there is any abnormal data, recalibrate or check the circuit connection.
Maintenance and guarantee
- Daily maintenance does not require professional operation. Regularly check whether the wiring is loose, whether the instrument housing is intact, and keep the display screen clean;
- If the measurement accuracy decreases after long-term use, zero and slope calibration can be performed again to restore the measurement accuracy;
- The product provides comprehensive technical support, accompanied by detailed operation manuals. For complex issues, please contact the manufacturer’s professional personnel for answers.
