Buffer-less Residual Analysers

ALLDOS (UK) bufferless residual chlorine/chlorine dioxide analysers are
increasingly being used by water companies to monitor final residual
levels in water before going through to the distribution network, within
the building services sector and food & beverages industries tomonitor
& control levels of chlorine dioxide for legionella prevention.
The ALLDOS Compact System utilises a Conex Multi amplifier &
controller that can be programmed for either parameter with pH and
temperature measurement and compensation and offers 1 alarm
relay, 2 controller relays and 4no 4-20mA outputs. The Aquacell flow
cell offers a unique motorised cleaning approach with an integrated
pt100 temperature probe, a sample water flow sensor with users
benefiting from a single point calibration. Pictured are units on a triple validation unit supplied to Water Tec Services Ltd in Scotland for the local water company.
