alpha-DO500
1/4-DIN 2-Wire Dissolved Oxygen Transmitter
with LCD
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
::
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.
::
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.
::
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.
