  • Enclosure Waterproof to IP65
  • Dual Set Point Control Relays
  • Earth Current Rejection
  • Easy to Install
  • Easy to Use
  • 4-20mA and 0-1 V DC Outputs
  • Australian Made

Dual Set Points are provided. The default setup for these are as "Too High" and "Too Low" control points. The user can also re-set them so that they are both "Too High" or both "Too Low" control points. An example of this type of setup is where the proCHEM unit has one point set to control the process, and a second point beyond that set to activate an alarm.

Separate LED's indicate when either of the Set Points has been exceeded. The output relays are rated to 240V and are fused at 1 Amps. Higher currents can be switched with an external contactor. 

All proCHEM units are easy to install. They are housed in a rugged plastic case which is non corrosive, waterproof and dustproof to IP65. All controls can be accessed via the hinged, clear cover. The large LCD display is easy to read, even from a distance.

The proCHEM series is designed for maximum flexibility. 4 to 20 mA and 0 to 1 V DC outputs are provided as standard.

For a total solution to your control requirements, TPS also offers a peristaltic pump, the easyFLOW-VS. The proCHEM series is proudly designed and manufactured in Australia. The TPS Quality System has been certified in accordance with AS/NZS ISO9001 standards. Since 1968, TPS has built a reputation for excellent backup service that is second to none.
