Fluke 721-360X Dual Sensor Precision Pressure Calibrator (2.48 bar)

Description

The Fluke 721-360X Dual Sensor Precision Pressure Calibrator (2.48 bar) can be used to measure static and differential pressure simultaneously. It is ideal for gas flow calibrations.

This instrument is available in seven models. Each of the models is supplied with two isolated, stainless steel pressure sensors: one standard 2.48 bar sensor and a selectable secondary sensor. For further information, please see the following table.

With the exception of the Fluke 721-3650’s 345 bar sensor (see the table above), each of the pressure modules supplied with the Fluke 721-360X Dual Sensor Precision Pressure Calibrator is able to conduct measurements to an accuracy of 0.025%. The pressure ranges available on this calibrator can be extended via the connection of Fluke’s 700 Series Pressure Modules (NOT included).

The Fluke 721-360X Dual Sensor Precision Pressure Calibrator’s suitability for gas custody transfer applications (gas flow calibrations) is cemented by the inclusion of a Pt100 RTD input through which the user may conduct temperature measurements using an OPTIONAL probe.

In addition to measuring pressure and temperature, the Fluke 721-360X Dual Sensor Precision Pressure Calibrator can also be used to measure DC voltages up to 30V and can conduct mA measurements between 4 and 20mA. Further to this, as well as including a 24V loop power supply for powering transmitters-under-investigation, the Fluke 721-360X Dual Sensor Precision Pressure Calibrator is capable of checking 24V loop power supplies.

Measurements acquired by up to three inputs may be viewed simultaneously on the Fluke 721-360X Dual Sensor Precision Pressure Calibrator’s large, backlit, graphic display.

Finally, the efficiency of this instrument is improved by its ability to save up to five instrument setups which may be recalled as required.

The Fluke 721-360X Dual Sensor Precision Pressure Calibrator (2.48 bar) puts versatility, efficiency and ease-of-use at the forefront of its design. It is ideal for those wishing to perform gas flow calibrations.
