Where gas mixes have a high proportion of one of the above gasses a unit will be supplied to measure the high proportion gas.
 

When installed within an enclosure, the ChillCard can be used as a point sensor. This uses the diffusion of refrigerant gas through the head shell membrane. When used as a point sensor, it is recommended that the the unit should be placed 30cm from the floor, as refrigerants are heavier than air.

When used as part of a multi-channel sampling system the ChillCard should be used in the flow through mod. Here the calibration port is used to supply gas to the head shell at the flow rate specified.

All  ChillCard sensors are  supplied fully tested and calibrated with a 1 year warranty against defective workmanship and parts reflecting its inherent reliability.
