Product Description

T4040 Online Dissolved Oxygen Controller

Industrial on-line microprocessor-based dissolved oxygen meter is a water quality on-line monitoring and control instrument. The instrument is equipped with polarographic dissolved oxygen electrode, which is widely used in power plants, petrochemical industry, metallurgical electronics, mining industry, paper industry, biological fermentation, medicine, food and beverage,water treatment, aquaculture and other industries.It continuously monitor and control the dissolved oxygen value and temperature value of water solutions.

Instrument features:
Color LCD display
Intelligent menu operation
Various automatic calibration functions
Multiple signal output modes
Two sets of relay control switches
Manual or automatic temperature compensation
High &low alarm, hysteresis control
Dissolved oxygen, temperature, state, etc.simultaneously showed on one screen
Password protect function to prevent mis-operation by non-staff
