Both Magnehelic and Capsuhelic gauges have an easy-to read 4" dial that quickly indicate LOW AIR AND GAS PRESSURES - positive, negative or differential.
Used to measure fan and blower pressures, filter resistance, air velocity, furnace draught, pressure drop across orifice plates, liquid levels with bubbler systems, pressures in fluid amplifier or fluidic systems; to check gas-air ratio controls, automatic valves, and monitor blood and respiratory pressures in medical equipment.
Magnehelic - More than 70 ranges, from 0-0.25"WG to 0-205kPa. Zero centre from .25-0-.25"WG to 15-0-15"WG. Low (to 105kPa)medium (to 240kPa) and high total internal pressure styles to 550kPa. Accuracy +/- 2% of scale
Capsuhelic - More than 60 ranges, from 0-50"WG to 0-2000kPa. Zero centre from 1-0-1"WG to -15-0-15"WG. Senstitive to low differential pressures yet withstands internal pressures to 3,500kPa. Accuracy +/- 3% of full scale
