Series MC Portable Multi-Cal Pressure Calibrator
from Dwyer Isntruments performs a wide variety of simple and complex pressure based
measurement, test, and calibration operations. Modular sensor design eanbles user to select pressure measurement range for application
flexibility. The MC calibrator can accommodate up to two interchangeable
pressure modules (sold separately below) in any combination of range or
accuracy.
The MC Calibrator simultaneously displays two separate measurements on the two line,
alphanumeric display. Readings can be displayed in a choice of seven
preprogrammed engineering units or any single user-defined unit.
The 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. 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.
The Multi-Cal Pressure Calibrator includes utility software, test leads,
protection module, adjustable had strap, AC adapter, two 9V batteries,
instruction manual, and hard carrying case.
Multi-Cal Pressure Modules are interchangeable and available in a
wide selection of pressure ranges and accuracies. Dwsyer pressure calibrators MC and MC6
accept up to two pressure modules. Modules include NIST calibration
certification.Modules are sold separately. See Below. Contact us for other pressure ranges and accuracies. FM-approved models are also available.
