Crystal Pressure P Series Pressure Comparator

P Series Pressure Comparator


The T-900 Series pneumatic hand pumps generate pressure and vacuum with precision and ease, allowing users to fine-tune the pressure delivered with every stroke. A built-in relief valve and dual pressure output enable safe and simple operation. The T-965 and T-975 are available with a button valve, making them capable of switching easily from pressure to vacuum gThe P-Series (System D) comparators are hydraulic screw pumps designed for easy, controlled, high pressure generation. Each comparator includes a 4 connection manifold, which can be used for the reference indicator, the device under test, a fine adjust, an isolation valve, or a fluid reservoir. The adjustable reference pressure port lets you set your reference gauge at the best viewing angle. Three models are available for hydraulic oil, water, or both.
