Each of the Fluke 721-160X Dual Sensor Precision Pressure Calibrator‘s pressure sensors is stainless steel and can perform measurements with an accuracy of 0.025% (excepting the Fluke 721-1650's 345 bar sensor). These isolated sensors are suitable for measuring static and differential pressures simultaneously. The Fluke 721-160X's additional ability to measure temperature via its Pt100 RTD input, and using an OPTIONAL probe, makes it suitable for gas custody transfer applications (gas flow calibrations).

If required, the Fluke 721-160X Dual Sensor Precision Pressure Calibrator’s pressure range may be extended via a connection with the Fluke 700 Series Pressure Modules (NOT included).

The Fluke 721-160X Dual Sensor Precision Pressure Calibrator is also capable of measuring 4 to 20mA signals and voltages up to 30V DC. Further to this, it can check 24V loop power supplies and includes a 24V loop power supply for powering the transmitter-under-investigation.

Measurements are indicated via the Fluke 721-160X Dual Sensor Precision Pressure Calibrator’s large, backlit, graphic display. It is possible to view up to three inputs simultaneously via this display, making this instrument both practical and easy-to-use.

Also adding to this instrument’s practicality and ease-of-use is its ability to save up to five instrument setups. These setups can be recalled when needed thereby improving the efficiency of this instrument.

The Fluke 721-160X Dual Sensor Precision Pressure Calibrator (1.1 bar) is a simple-to-use, versatile and practical instrument. It is suitable for a variety of measurement applications and is ideal for performing gas flow calibrations quickly and easily.
