The P/N 001246 Calibration Stand provides the unique setup for customer calibration and gas testing of Bridge MAP gas analyzers.  The Calibration Stand provides all the unique items required to interface the MAP gas analyzer to the test gas regulator of customer calibration gas.  All the user needs to provide is an appropriate length of 1/8^th inch diameter metal of plastic tubing between the regulator output valve and the calibration stand input

The calibration stand comes complete with a flowmeter/adjuster, a tee assembly to ensure the delivered gas is at atmospheric pressure, and a tubing interface to provide a gas-tight seal to the sample needle of the Bridge MAP Headspace Gas Analyzer.

The calibration stand may be used to adjust and ensure that test gas delivered to the analyzer is at slightly greater than the intrinsic flow rate of the analyzer, while still maintaining atmospheric pressure at the sample needle.  The flow rate is monitored by a flowmeter built into the calibration stand, and adjusted by a built in needle valve at the base of the flow meter.

The calibration stand is simply connected to the calibration tank regulator output set to about 20 PSI pressure, the test gas cylinder valve is opened, and the calibration stand flow is adjusted by the needle valve on the flowmeter to provide test gas to the analyzer.  The use of this unique calibration stand ensures that calibration gas is delivered to the analyzer under the same conditions as a real package – ensuring that customer calibration provides the best correlation possible to real package testing.
