Hand pumps compatible with air and liquid for manually applying and setting calibration test pressures

Hand Pumps for generating Calibration Pressures
Combine with a master test gauge and use as a pressure comparator for inspecting pressure measuring devices as part of your ISO9000 quality procedures. Apply air or hydraulic pressures to a high precision for checking dial gauge cardinal points, sensor output signals, switch contact points and displayed readings.



Measurement Type
Instrumentation for differential pressure monitoring

Differential Pressure Sensing
Measure very low range air pressures such as the delta pressure between two rooms to keep out contaminants or to contain hazardous substances. Determine the flow rate or of liquids or gases by measuring the difference in pressure across a restriction in a pipe.



Sensors and instruments for measuring absolute pressure ranges

Absolute Pressure Measurement
Measure pressures with reference to high vacuum where it is not required to compensate for changes in atmospheric pressure such as leak testing or controlling pressures in an environmental chamber.



Sensors, loggers and indicators for monitoring and recording atmospheric pressure

Barometric Pressure Measurement
Sensors, loggers and indicators for atmospheric pressure monitoring of ambient or controlled conditions in industrial and research applications.



Sensors and instruments for measuring and logging fluid level

Liquid Level Sensing
Hydrostatic pressure sensors for lowering down into a borehole to monitor groundwater level or fitting to the outside of a storage tank to determine the volume of its liquid contents.

Applications

Find the pressure transducer or instrument that you are looking for by either selecting a specific pressure measurement application or industry category from the left hand menu.


Resources

Look up pressure measurement terminology which you will often find on pressure measurement related product data sheets and within the content of this website.

On each pressure sensor & instrument product page you will find a tool to convert pressure units, convert altitude into pressure units, convert temperature units and explain IP ratings.

If you would rather leave it to us to choose the appropriate pressure transducer or digital indicator for you, then please specify a pressure sensor using PSAT for any application and submit it online to receive product information or a quotation specific to your requirements.

If you require a digital readout, alarm relays or a control signal you can define a digital indicator or controller using ISAT for measuring and displaying the reading from a pressure sensor.
