Description
The WatchGas Aluminum Telescopic Probe puts up to 75 cm of reach between your team and the hazard zone. Extend the probe to sample ahead into ducts, vessels, confined-space manholes, or overhead spaces before committing personnel — a standard practice under OSHA 29 CFR 1910.146 Appendix B pre-entry atmospheric testing. The Teflon-lined interior protects reactive gas sensors from heat, moisture, and contamination during the sample draw. When the job is done, the probe collapses and rolls into the included carrying pouch for site-ready storage alongside your
SST4 Pump monitor.
Supports both pumped and diffusion sampling configurations. For a longer, static-dissipating fixed probe designed for ATEX environments with ignition risk, see the
Fixed Carbon Fiber Probe.
Includes:
- Aluminum telescopic probe (extends to 75 cm)
- Teflon-lined tubing
- Luer fitting
- Carrying pouch
Part Number:
WG-008-3015-001
Frequently Asked Questions
Why does OSHA require atmospheric testing before confined-space entry, and how does this probe support that requirement?
OSHA 29 CFR 1910.146 Appendix B requires that the atmosphere of a permit-required confined space be tested for oxygen content, flammable gases and vapors, and toxic air contaminants before any authorized entrant enters. The WatchGas Telescopic Probe enables pre-entry sampling without a person entering the space — you extend the probe through the manhole or hatch, start the sample draw on your
SST4-PUMP, and confirm the atmosphere is within OSHA's permit thresholds before the entry team steps in.
What is the maximum reach of this telescopic probe?
The WG-008-3015-001 extends to 75 cm (approximately 29.5 inches). For manholes, tank hatches, and duct penetrations where the hazard zone is within arm's-reach depth, 75 cm is sufficient for pre-entry testing. For deeper spaces, pair this probe with additional sampling tubing, or consider the 100 cm
Fixed Carbon Fiber Probe with its included 2 m Last-O-More hose for extended reach.
Why is Teflon lining important in a sampling probe?
Standard tubing materials (rubber, PVC, some plastics) can adsorb reactive gases — particularly H2S, SO2, and HCN — onto their inner surfaces, lowering the concentration that reaches the sensor. Teflon (PTFE) is chemically inert and essentially non-adsorbing, so the gas concentration at the probe tip is the same as the concentration at the sensor inlet.
Can this probe be used with diffusion-mode monitors as well as pump-draw monitors?
The probe supports both modes. In pump-draw mode (with an
SST4-PUMP), the instrument actively draws atmosphere through the probe. In diffusion mode, the probe channels the atmosphere to the sensor without active sampling — useful for spot checks in accessible spaces.
What is the difference between this aluminum telescopic probe and the fixed carbon fiber probe?
The aluminum telescopic probe extends from a compact form factor to 75 cm — ideal for portability and varied-depth pre-entry testing from a pouch. The
Fixed Carbon Fiber Probe is a 100 cm fixed-length probe made from carbon fiber, which dissipates static electricity — a critical property in ATEX-classified environments where electrostatic discharge could trigger ignition. If your site involves flammable atmospheres or explosive dust, the carbon fiber probe is the safer choice.
