Type DIBTA 16 PORT DA8106 and Type: DAN-HP-4 Port DA8124
Table top unit with screwed casing. The analyser unit is hermetically sealed
Sheet aluminum housing with plastic case.
Width: 45 cm
Height: 27,5 cm
Depth: 53 cm (50 cm without tubes))
All gases are transported within the analyser by the integrated feed pump. The surrounding air destined for rinsing is lead across a filter (optional Nafion, soda lime) for processing and protecting the analyser. CO2-free air (zero gas) is produced by piping surrounding air through a absorber containing soda lime.
4 to 16 sample ports for breath bags from which measuring gas is pumped into the analyser; inlet port for rinsing gas and extra gas each; gas outlet.
24VDC max. 4A, typ. 1,5A - the device has been tested according to EN 60601-1-2: 12.2007 for Electromagnetic Compatibility and therefore exceeds the requirements of the EN 61326.
In accordance with EEC low voltage directive 2006/95/EG
