Multi-Cal Benchtop Calibrator
Interchangeable Ranges, ± 0.05% Accuracy, Datalogging Capability, NIST Traceable


Model MC6 Multi-Cal Benchtop Calibrator performs a wide variety of simple and complex pressure based measurement, test, and calibration operations. Modular sensor design allows user to select pressure measurement range for application flexibility. Calibrator can accommodate up to two interchangeable pressure modules (sold separately below) in any combination of range or accuracy.

Simultaneously display two separate measurements on the two line, alphanumeric display. Readings can be displayed in a choice of twelve preprogrammed engineering units or any single user-defined unit. Calibrator features min/max recall, hi/lo alarm, percentage of full scale pressure readings, mA/voltage measurement, leak rate and pressure decay measurement, switch testing capabilities, including trip point and dead band, and velocity/volume flow rates.

Quickly document calibration procedures using the data logging feature which stores up to 384 sets of pressure and time/date stamped measurements. The automatic % error calculation simplifies transmitter calibration. Easily upload stored data to an IBM compatible computer via the RS232 two-way communications port. Calibrators and modules include certification to NIST traceability--ideal as a secondary standard for calibrating pressure equipment.

Multi-Cal Pressure Calibrator includes utility software, test leads, protection module, adjustment handle, AC adapter, and instruction manual.
