K. R. - Optical Dissolved Oxygen Analyzer

Function
Online multi parameter water quality monitoring control instrument, multi sensor can be connected and monitored by the single transmitter.

Typical use
This instrument is widely used in online monitoring of water supply, tap water, rural drinking water, circulating water, washing film water. disinfection water, pool water, and other industrial processes. itcontinues monitors and controls residual chlorine and temperature valuein aqueous solution.

Mains Supply
85-265 VAC +/-10%, 50 +/- 1Hz, Power ≤ 3W;
9-36 VDC power consumption ≤3W

• Large display, standard 485 communications, with online and offline alarm, 98*98*130mm meter size.92.5*92.5 mm hole size, large screen display.
• Historical Curve: The residual chlorine measurement data can be stored automatically every 5 minutes, and the parameters value can be storedcontinuously for a month. Provide standard solution calibration and fieldcalibration.
• Built in various measurement functions. one machine with multiple functions.
• meeting the requirement of various measurement
• The design of the whole machine is waterproof and dustproof. and the backcover of the connection terminal is added to extend the service life in harsh environments.
• Panel/wall/pipe Installation. three option available to meet various industrialinstallation requirements.
• Same interface displays, input value, temperature, current value, etc.
• Password protection to prevent non-staff error operation

All the connection from the Instrument, the power supply, output signal, relay alarm contact and the sensor are connected within the transmitter. the length of the lead wire for the fixed electrode is usually 5 -10 meter, proper label and colour on the sensor are mentioned to connect to the transmitter which are to be connected and tighten.
