SYSTEM OVERVIEW:
The Dual TDS Monitor with RO controller is an advance microprocessor controlled TDS meter and RO
controller in one unit. This unit will display TDS in PPM from two temperature compensated conductivity
probes and provide all standard RO functions. Two probe inputs are available, one for feed water and the other
for product water. The difference from each probe can also be read as percent rejection. Temperature
measurements and alarm points are also available. This manual will cover the use and operation of the Dual TDS
Monitor / RO controller.
TDS FEATURES:
•
Dual conductivity probes support. (The monitor may be used with one or two probes).
•
Temperature compensated PPM measurements.
•
Auto ranging from 0 to 9999 PPM.
•
Temperature measurement on each probe in degree C or F.
•
Percent Reject measurement when using two conductivity probes.
•
Alarm limits are user adjustable on PPM and temperature for both probes.
•
Alarm limits are user adjustable on Percent Rejection when using two probes.
•
Alarm relay with user adjustable time delay.
•
Alarm relay may be set to stay latched, holding the last alarm.
•
Operates on multiple low and high voltages.
•
Panel mount plastic enclosure.
