Key words:
gas chamber, gas sensor, testing

Characterization:

A gas chamber for testing the gas sensing properties of substrates with an active layer. The gas is inserted to the chamber from external gas station rig. The main advantage of the chamber is built heating platform that enables characterization of gas sensor structures without the need of any package which increases the efficiency of new active materials development. Contacting is performed using variable arms terminated with gold-plated flexible contacts (pogopins). The chamber is made of high chemical and temperature resistant plastic materials Ketron Peek-1000 (PEEK) and stainless steel AISI 316L.

Parameters:

Chamber diameters (l x w x h): 100 mm x 80 mm x 30 mm

Gas volume without sensor: 0,126 l

Inlet/outlet: stainless stell tube, 6 mm in outer diameter

Max. sample heating temperature: 300 °C

Power supply: DC controlled current supply 0-6 A
