MicroCal

Advanced Modular

Pressure Calibrator

The MicroCal™ automated pressure calibrator is used as a
stand-alone calibration standard for dierential and gauge
pressure sensors found in critical environments. Setra part­nered with NASA to develop the industry’s quickest and most
stable pressure control for low range applications. The Micro­Cal™ combines precise pressure control with high accuracy
modular pressure references providing the quickest and most
accurate calibration solution available on the market today.
The MicroCal™ is an easy-to-use solution that signicantly im­proves labor productivity and eciency when compared to
the leading competitors, providing immediate ROI.

Modular Design to Cover Many Applications

The MicroCal™ utilizes modular pressure references, enabling
the user to select the most accurate reference for calibrating
the unit under test. Competitive calibrators often use xed
higher range reference sensors that do not allow for proper
calibration ratios at the low end of the pressure range. The
modular rechargeable battery oers further exibility to ex­tend available calibration time beyond the standard 8 hours.

NASA Patented Technology

The MicroCal™ is designed to perform calibration checks on
installed sensors, pressure switches and gauges that monitor
critical applications. The on-board pressure generation system
allows for stable & accurate pressure to be applied to the unit
under test during calibration, while providing isolation from
process background disturbances. This NASA patented tech­nology achieves 0.0002 “W.C./step resolution; when combined
with the high accuracy MCPM pressure module the MicroCal™

is the ultimate low-pressure calibration device.

Reduce Calibration Time

When the fast and stable pressure control is combined with
high accuracy reference modules and easy to use interface,
the MicroCal™ can reduce overall calibration time up to 80%.
This time savings provides almost immediate ROI based on the

number of calibrations performed annually.

7” Touchscreen With Intuitive User Interface

The easy to use 7” touchscreen interface, combined with an in­tuitive menu structure, provides the user with all the features
needed for verication and calibration of dierential pressure
instrumentation. The MicroCal™ oers the Expert System fea­ture, which detects and automatically calibrates Setra’s Model
269 digital pressure transducer.
