Air Filter and Sample Tubing
A cylindrical particle filter with a short length of tubing is supplied with the SDM-2012
for installation to the AIR fitting on the back panel. The filter keeps particulate
contamination out of the docking station.
Two types of sample tubes are included with the docking station. Two 3 foot lengths
of 3/16 inch ID polyurethane tubing are provided to connect the regulator on a
calibration cylinder to the GAS 1 and GAS 2 fittings on the back panel. In addition, a
10 foot length of 5/16 inch ID polyurethane tubing is provided for connection to the
exhaust fitting on the back panel to allow routing of the exhaust to a location such as
an open window where the exhaust can disperse.
WARNING:
Do not use an exhaust tube that is longer than 10 feet. The increased flow
restriction caused by a longer tube may affect gas response and cause
inaccurate calibration and bump test results.
