Overview
Agro Enviro Tests dissolved oxygen analyser is one of the intelligent online chemical analysis instruments. It is widely used in continuous monitoring of dissolved oxygen, saturation, oxygen partial pressure and temperature. The continuous monitoring data is realized by remote transmission monitoring and recording through the transmission output connection recorder.
Features
- Using photoelectric technology, low maintenance rate and high stability
- No oxygen consumption, no flow rate requirements, can be measured by purified water
- Good compatibility, the sensor provides standard 4 mA to 20 mA signal, which can be interchanged with E+H sensor
- Strong anti-interference ability, full digital processing technology and full stainless steel shell shielding
- Automatic temperature compensation
