Product updates, technical explainers and application know-how.
The standard four are LEL, O2, CO and H2S β the most common risks in confined spaces. From there you can extend to five, six or seven gases by adding NH3, Cl2, SO2, VOC and others; full 2-in-1 to 7-in-1 customization is available.
Fixed detectors provide area coverage with 24/7 monitoring wired into the DCS; portable units handle patrols and pre-entry checks for confined spaces. Together they form a complete safety monitoring system.
Fence-line monitoring addresses fugitive emissions affecting the surroundings, with detectors along the site boundary; stack monitoring addresses organized emissions and is installed on exhaust stacks. Purpose, layout and data use all differ.
Heavier-than-air gases: 0.3β0.6 m above floor. Lighter-than-air gases: 0.5β2 m above the leak source. Oxygen detectors: about 1.5 m, close to the breathing zone.
Electrochemical suits low-concentration toxic gases with low power draw; PID suits VOC with ppb resolution; NDIR suits CO2 / CH4 with long life; catalytic bead suits combustible LEL detection.
Test before entry, monitor continuously during work, and keep the detector on the worker. Test in this order: oxygen β flammables β toxic gases. Entry is permitted only after readings pass.
