Alpha DO500 ¼ DIN 2-Wire Dissolved Oxygen Transmitter

The Eutech alpha DO 500 1/4-DIN 2-wire dissolved oxygen transmitter features improved circuitry design that prevents ground loop effects and provides high reliability in the measurement of Dissolved Oxygen.
With advanced diagnostic capabilities, excellent flexibility and minimal maintenance, the alpha 500 series transmitters are the perfect instruments to complete your systems in aquaculture, chemical processing or water and wastewater treatment industries.

 

Product Features

 

:: Advanced diagnostics like ‘out-of-range’ and ‘hold’ indicators help in monitor and process control. Clear annunciators and easy-to-read dual-line display enables instantaneous view of measured readings and set-up configurations for effortless installation and operation. In addition, scalable 4 to 20 mA current output resolution ensures better resolution at chart recorder or other peripheral devices. Suitable for indoor and outdoor use with its IP65-rated weatherproof housing, the alpha 500 series transmitter can be wall or panel mounted according to industrial requirements.

:: Intuitive push-button user-interface ensures easy calibration and set-up for everyone. The offset adjustment feature enables you to correct readings conveniently without the need to remove the electrode on-site.

:: The alpha 500 series transmitter prevents output interference due to electrical noise or leakage from the input source. Cross-talk between multiple transmitters in a serial loop is eliminated for better accuracy. In addition, operations are not disrupted even if one unit requires maintenance as the transmitters operate on a 12 to 24 V D.C. power supply.
