Overview
Enviro Test Construct digital turbidity sensor dissolved oxygen sensor uses fluorescence measurement of dissolved oxygen, blue light emitted by the phosphor layer, a fluorescent substance is excited to emit red light, and the fluorescent substance and the concentration of oxygen is inversely proportional to the time back to the ground state.
Features
- Extremely quick and precision optical dissolved oxygen sensor
- It’s suitable for harsh applications and free maintenance, saving cost
- Special light source technology for long working life of dissolved oxygen sensor.
- Provide two ways of 4 to 20 mA output for dissolved oxygen and temperature.
- Digital Optical DO Sensor provides precision and online measurement
- With the data recording function, users easily check history data and history curve
