Pipe Mounting Kit: Magnehelic® gauges can be surface or panel mounted with hardware supplied. The preferred calibrated mounting orientation is vertical. Using the pipe mounting kit, the unit can be bolted to horizontal or vertical pipework, 1 1/4" to 2" OD.

Line Filter: When working with dirty gas lines these 40 micron sintered bronze filter elements prevent dirt and dust entering the gauge. Elements have 1/8" female and 1/8" male NPT threads to fit the Magnehelic® ports. Two required per gauge.

Portable Kit: To store the Magnehelic® gauge and equip it for portable use, this protective carrying case contains a table stand to hang the gauge vertically, and 2.5 metres of rubber tube. A spring tube holder can be used in an 8mm hole in a duct wall to retain the pressure sensing tube.

Safety Relief Valve: A Brass safety relief valve protects the Magnehelic® against accidental overpressure. This opens at 10psig, and is designed for mounting in a 1/4" NPT tee in the sensing line. Alternatively it can be fitted in the unused Magnehelic® port by using the A-349 Brass reducer.

Air Filter Kit: For monitoring DP across air filters, this kit provides two static pressure sensing probes, two 1.5m lengths of 6mm aluminium tubing and two vent valves. Both valves and probes have integral compression fittings. The vent valves allow zero checking without disturbing the sensor lines. A wall mounting plate is also included, to fit the Magnehelic®.
