Gas-Sentry Model CGO-321
Three-In-One Fast and Accurate
Dual scale natural gas detection, fast gas leak location, and oxygen detection in a compact, rugged instrument is the tool of choice for a wide range of outdoor, indoor, and underground gas detection jobs.
Gas, LEL, and oxygen levels are displayed by selecting the appropriate scale. The optimal gas sensor (catalytic combustion or thermal conductivity) is selected automatically resulting in an accurate reading over the full range (0.03 to 100%) of gas. An electrochemical oxygen sensor detects both oxygen deficient and oxygen excess conditions by covering the 0 to 40% range. A fast TRACK GAS scale helps locate gas leaks quickly.
Levels of both oxygen and natural gas are checked every few seconds no matter what scale is used - except when bar-holing and leak locating on the %GAS and TRACK GAS scales. If oxygen or natural gas is at an unsafe level, the unit alarms both by flashing O2 or LEL on the display and sounding the acoustic alarm.
The detector comes with a standard 12 inch two piece probe, a manual, a laminated short guide to operation, a set of batteries, a carryall with pouch for the probe, and a shoulder strap. Also included is:
Automatic Calibration (A-CAL TM)
Automatic calibration is a standard feature built into all Gas-Sentry detectors. Using Bascom-Turner's calibration gas, delivered either manually or by an automatic gas dispenser, detectors are automatically calibrated in about 30 seconds.
Lifetime Limited Warranty
There is a lifetime limited warranty on the detector's electronics and a three year limited warranty on sensors applicable to detectors and sensors in the USA. The pump and accessories are warranted for one year.
Intrinsically Safe
UL listed for hazardous locations, Class 1, Div. 1, Groups A, B, C, and D.
Options
-
Docking Calibration (D-CAL TM) - Optional hardware and software allow automatic bi-directional serial IR communication between a Gas-Sentry, equipped with an optional sapphire window, and a docking station for calibration verification and record-keeping.
-
Landfill Gas Sensor - CGO-321L has a special PS-001 sensor for improved accuracy when sampling mixtures of methane and carbon dioxide found in landfill gas.
-
Gooseneck Probe - for even faster leak location when using the TRACK GAS scale.
-
Bar Hole Probes - clear plastic, fiberglass, and stainless steel long probes for underground leak location.
-
Straight Hose - replace coiled hose with five or ten feet of straight hose for longer reach.
-
Instrument Case - for storage of detector and accessories.
