CERTIFICATION option – all gauges

If you need to know 100% that your pressure gauge is accurate and within specification, or demonstrate to your client, we offer a gauge certification service. Your gauge is calibrated against our high-accuracy digital master gauge and a unique certificate is issued, cross-referenced to your gauge.

NO-LOSS CONNECTOR option – 100mm gauges

A no-loss connector is an automatic valve with a 3/8” female port for your gauge, and a ½” male connector for your pipework. When the gauge is in place, the valve is open and the gauge will read the system pressure. If you need to remove the gauge for replacement or checking, the valve automatically closes so there is no need to separately isolate or drain your system.
