Installation

The gas bottle is not supplied and must be purchased locally. To ensure the calibration works

correctly, the calibration gas bottles must be of 99.999% (50) quality or better. Bottles containing

34 liters of compressed gas, with a 5/8-18 UNF (C10) fitting are compatible with the hand-held

calibration device and recommended for this purpose.

Empty gas bottles are easily removed from the device. Simply unscrew the small black screw

(No. 3 in Figure 25) a few turns, slide the bottle out of the black plastic holder, and unscrew the

bottle from the pressure reducer. Follow this same procedure in reverse order to install a new

bottle.

3.10.2 ORBISPHERE flow chambers

Note: This is the recommended option for the K1100 sensors.

The ORBISPHERE flow chambers are used to draw the calibration sample past the sensor.

They connect to 6-mm or ¼" stainless steel tubing by means of two Swagelok™ fittings. If

necessary, copper or plastic tubing with low permeability can be substituted.

Dimensions of sensor and flow chamber assembly :

• Width: 50 mm

• Height: 210 mm

(add 100 mm for connection length)
