Our PRM Series helps insure your filtration system is functioning properly and alerts you whenever servicing is required. They’ve become popular among a growing range of Aquatec customers, from sophisticated labwater system manufacturers to basic aquarium owners. They provide extra level of insurance that is oftentimes required. These monitors are actually comparative circuits that continually monitor membrane performance. LED
output indicates whenever the membrane needs service or replacement. The PRM Series
incorporates logic output which is suitable for interface with alarms or other external controls.
The PRM Series includes two (2) sensor probes which fit into standard 1/4” John Guest or Jaco
fittings. The PRM Series is available in several different electrical configurations, including 24 VAC, 24 VDC, 12 VDC, 5 VDC and 3 VDC (24VAC version shown above). Our miniaturized 3 VDC circuit is compact enough to be mounted on the backside of a standard, 3V battery holder.
