Gas Probes

 

0.33m Gas Probe

 

Use this hand held gas probe to pinpoint the source of a leak or submerse the probe to determine exhaust gas concentrations.

 

Specifications

Path Length: 0.33m

Dimensions: 7″ x 1.25″ (17.8cm x 3.2cm)

Weight: 1lb (0.45kg)

 

1.0m Gas Probe

 

For applications requiring lower detection limits, the 1.0m Gas Probe is the preferred choice. Its longer path length coupled with its small size produces detections in the most confining spaces.
