T4040 Online Dissolved Oxygen Controller

The microprocessor-based industrial online dissolved oxygen meter is a water quality online monitoring and control instrument. The instrument is equipped with a polarographic dissolved oxygen electrode, which is widely used in power plants, petrochemicals, metallurgical electronics, mining, papermaking, bio-fermentation, medicine, food and beverage, water treatment, aquaculture and other industries to continuously monitor and control the dissolved oxygen value and temperature value.

Instrument Features:
color liquid crystal display
Smart menu operation
Various automatic calibration functions
Various signal output methods
Two groups of relay control switches
Manual or automatic temperature compensation
High and low alarm, hysteresis control
Dissolved oxygen, temperature, status, etc. are displayed on one screen at the same time
Password protection function to prevent misuse by non-staff
