The highest user availability rate on the market

Easy to use and maintain

Thanks to its unique technology, the AP4C has the shortest recovery time even after being exposed to high concentrations of chemicals. Designed for field use, the AP4C removes complexity: one single ON/OFF button, no setting or menu, no field calibration and filter. The entire detection process is automatic. An annual check is the only required maintenance operation.

Ideal in tough conditions

The AP4C has the capacity to work in very severe environmental conditions and the measurements are unaffected by high humidity levels or by the presence of other organic chemical compounds such as paint or diesel smoke. Moreover the AP4C can run in highly explosive areas.

Optional kit

The AP4C comes with optional kits including the S4PF liquid sampler and extra consumables.
