alpha DO 500 משדר חמצן מומס דו-גידי דגם A-DO-500

Product Features

v	Easy installation and operation 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.

v	Fuss-free, easy maintenance 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.

v	Optimal performance in demanding applications 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.
