| 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. |
