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
(number 3 in Figure 24) 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)
