Feature
1. Digital sensor, directly output Rs-485 digital signal, support MODBUS/RTU
2. Built in temperature and pressure sensors, which can automatically compensate; Built in salinity compensation
3. Optical design, no electrolyte consumption, no oxygen consumption during measurement
4. Increase filter design, resist light source interference, and have good stability
5. No preheating and power on polarization are required, and the response speed is fast. The fastest response is 40 seconds (T90)
6. The fluorescent cap is easy to replace, with lower maintenance cost and longer service life
7. The surface shall be subject to anti-corrosion and passivation treatment
8. Low power consumption of sensor and anti-interference design of internal circuit
