The Desiccant Head Assembly
Keeping the sensor dry between tests ensures that the instrument is always ready to carry out rapid spot checks. The unique design of the desiccant head achieves this by surrounding the sensor with desiccant before the head is lifted for sampling.
At no time is the sensor allowed to come into contact with ambient air. The chamber is also designed so that the void space and chamber wall surfaces are purged with sample gas, prior to exposure of the sensor, giving faster, more accurate and reliable results.
