Description:
The Pressure Sentry is a compact device capable of detecting low pressure in combination boiler heating systems. The device provides an audio-visual alert if system pressure falls below a set point. It can be installed within minutes to most radiators and can help heating engineers and plumbers to reduce costs but avoiding unnecessary emergency call outs. It uses a standard half inch BSP screw thread and has a small battery for the alarm, only drawing power when low pressure is detected.
