|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
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
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
Multi-Cal Pressure Modules are interchangeable and available
in a wide selection of pressure ranges and accuracies. Benchtop
calibrator accepts up to two pressure modules. Modules include
NIST calibration certification.
