Price: From $459.87 to $1,037.83
Economical solution for calibration of low pressure differential transmitters. Simple direct-acting pump action with fine adjustment piston makes an easy and precise pressure setting. Not for use in Oxygen systems.
|
Price: From $5,495.03 to $6,418.84
Self contained unit provides a precise nitrogen source for calibrating differential and static pressure instrumentation using an external pressure calibrator
|
Price: From $626.12 to $1,204.08
Ideal solution for either differential pressure or vacuum calibration using precision test gauge or pressure calibrator as the pressure reference. Not for use in Oxygen systems.
|
Price: From $459.87 to $1,037.83
An outstanding solution for performing vacuum calibration in the laboratory or in the field where the pressure reference is attached to the pump with integral test gauge adapter. Not for use in Oxygen systems.
|
Price: From $1,886.63 to $2,811.04
Perform both ultra-precise low pressure differential or high pressure static pressure calibrations with nitrogen using the same device.
|
Price: From $865.69 to $1,433.75
An outstanding solution for taking gas samples in the field for analysis in the lab. The SP0V gas sampling pump pulls low pressure gas from a well and boosts it to 25 psi to pump it into a sample cylinder.
|
Price: From $367.90 to $1,750.42
An excellent solution for doing static pressure calibrations with compressed nitrogen gas. Brass and stainless steel manifolds are available to provide solutions for every type of environment.
|
Lightweight, high pressure source that can use oil or water as the test fluid.
