Introduction: Doz-7600 is a microcomputer-based online ozone monitoring instrument in the water, the use of advanced non-membrane constant voltage sensor, without changing the diaphragm and pharmaceutical, high sensitivity, rapid response, accurate measurement, stable performance and easy maintenance. The ozone monitoring system in the water has the advantages of convenient use, high accuracy and economy. Use this series of advanced analytical techniques to ensure the long-term stability of the instrument reliability and accuracy. With Chinese menu operation, 485 communication and other functions. For drinking water treatment plants, drinking water distribution network, swimming pool, cooling circulating water, water treatment works on the ozone solution in aqueous solution for continuous monitoring and control. Features: 1 large dot matrix LCD display, English menu operation. 2 multiple parameters at the same time display: ozone value, temperature, output current at the same time display, intuitive and easy to read, and range limit tips. 3 to restore the factory settings function, slope correction function. 4 manual / automatic temperature compensation. 5 communication function (optional): with rs-485 communication interface (modbus protocol is partially compatible), 4 ~ 20 ma current output corresponding to the ozone value can be arbitrarily set. 6 photoelectric isolation 4-20ma current output. 7 Hysteresis Any setting function, to avoid the frequent switch relay action, there are set the switch off and off. 8 watchdog function: to ensure that the instrument will not crash. 9 core devices are from well-known foreign brands. 10 power-down protection> 10 years.
