Frontline LEDPOINT PRS

Description

The LEDPoint® PRS is a hydrocarbon detector specifically designed to offer a cost-effective alternative to Pellistor or Catalytic based flammable gas point sensors.

The LEDPoint® PRS consists of the dual beam, dual wavelength, infrared LED (light emitting diode) based, Patented, gas sensor cell plus all drive electronics required to give a temperature corrected, linear output proportional to gas concentration. This interface duplicates standard Pellistor outputs enabling the LEDPoint® PRS to be used with existing wiring, monitoring, power supply and junction box installations.

The LEDPoint® PRS can be used in the harshest environments and, as it can be fitted to existing power and signal wiring, it is a true “plug and play” replacement for existing pellistor type sensors.
