| The all-new microCHEM series are
a simple, no fuss solution for many water quality monitoring applications.
With industry-standard 0 to 1 V DC and 0 to 5 V DC outputs, they are designed
specifically to interface with commercial dataloggers and PLC units.
All microCHEM units are easy to install. The enclosure is waterproof to IP65, so a separate cabinet is not required. Waterproof cable glands are provided for the
input and output cables.
The microCHEM series is the best value range of water
quality transmitter available today. They are ideal for environmental monitoring,
cooling tower control, and any industrial site utilising centralised control
systems. |
The microCHEM series is an excellent solution
for Original Equipment Manufactures (OEM's) who wish to incorporate water
quality monitoring into their own designs. Over 30 years experience in
this industry ensures that the microCHEM series provide accuracy
and reliability without the OEM needing to spend any time or money on R
& D.
For even greater output flexibility, ask about the 420 ToolBox. This module provides such features as reversing
the voltage signal, 4 - 20 mA output, control relay, RS232 interface or
pulsed output.
The microCHEM series is proudly designed and manufactured in Australia. The TPS Quality System has been certified in accordance with AS/NZS ISO9001 standards. You can always be assured of the best quality, service and value for money. |
