Nobo - Model DOZ-7600 - Online Dissolve Ozone Meter
From Dissolved Ozone
Ozone detector is a microcomputer type on-line measurement and control device for ozone in water. It adopts advanced non-membrane constant voltage sensor, no need to replace the diaphragm and solution. It has high sensitivity, fast signal response, accurate measurement, stable performance and simple maintenance.The water ozone measurement and control system has the characteristics of convenience, high accuracy and economy.This series of advanced analytical techniques are used to ensure the stability, reliability and accuracy of the instrument in its long-term operation. It has English menu operation, 485 communication and other functions. It is used for continuous monitoring and control of ozone content in water treatment plants, canning plants, drinking water distribution network
- Large screen LCD display, support Chinese - English menu (switching from each other).
- Multi parameter display at the same time: ozone value, temperature, output current and other simultaneous display, intuitive and easy to read, with range over limit indication.
- Superior has the function of restoring the factory setting.
- Manual operation/Automatic temperature compensation function
- Communicate function(Optional): RS-485 communication interface (MODBUS protocol partially compatible), the value corresponding to the4-20mA current output can be arbitrarily set, photoelectric isolation4-20mA current output
- The function of setting hysteresis random, avoiding the frequent action of switch relay, has the function of setting switch off and closing.
- Watchdog function: make sure the meter doesn't crash.
