Multi-Cal Pressure Calibrator
Interchangeable Ranges, ±0.05% Accuracy, Datalogging Capability, NIST Traceable
Series MC Portable Multi-Cal Pressure 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 12 preprogrammed engineering units or any single
user-defined unit. Calibrator features min/max recall, hi/lo alarm, percentage of full-scale
Pressure Calibrators
pressure readings, mA/voltage measurement, leak rate and pressure decay measurement,
switch testing capabilities, including trip point and deadband, 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. Easily upload stored data to
an IBM compatible computer via the RS232 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,
adjustable hand strap, AC adapter, batteries, instruction manual, and hard carrying case.
APPLICATIONS
Pressure measurement for clean room control, filter performance monitoring, HVAC
testing and setup, draft measurement, airflow measurement control, differential pressure
measurement in laminar flowhoods, paint booths, industrial ovens and fume hoods.
Use as a secondary standard for calibrating pressure equipment.
Multi-Cal Pressure Modules are interchangeable and available in a wide selection
of pressure ranges and accuracies. Handheld calibrator accepts up to two pressure
modules. Modules include NIST calibration certification.
