Low Pressure Gauge
Durable materials and robust construction for long service life, rezero capability, 150% overpressure with no effect on calibration
Also known as a draft gauge, a low pressure bellows gauge is typically utilized for measuring low pressures from 25” water column up to 400” water column, or approximately 15 psi. 3D Instruments’ low pressure gauge incorporates a highly sensitive diaphragm bellows to measure pressure. The brass bellows expands with increasing pressure, thereby driving the gearing mechanism and pointer.
Our low pressure gauge models feature 316 stainless steel components and a 4.5” case, constructed of either ABS or 300 series stainless steel. The robust 3D Instruments draft gauge is the perfect solution for your demanding low pressure measurement applications.
