After a preset time, the Model RGO-321 can display peak and sustained bar-hole gas readings
Accurate, Rugged and "Smart" Gas Detector For Utilities
The all-weather, Gas-Ranger detector, specifically designed for gas and other utility personnel, can be used to track gas leaks, bar-hole, and to monitor ambient air for safe levels of natural gas and oxygen. Two types of natural gas sensors, an electrochemical oxygen sensor, a built-in 2 liter/minute pump, and microprocessor control provides accurate and fast gas and oxygen readings. The Gas-Ranger is used for leak location, bar holing, and verifying safe levels of both gas and oxygen while working in confined and enclosed spaces. Now you can carry one detector and do the whole job both indoors and outdoors.
Gas-Ranger Operational Description
Bar hole gas measurements are made easily and consistently with the detector's built-in pump, automatic timer and memory. All gases are monitored continuously and the unit alerts aubibly and visually (e.g. GAS, HiO2, LoO2) when one or more gases are outside their alarm limits. All models have a TRACK GAS scale for quick leak locating sensitive to 0.005% GAS (0.1% LEL or 50 ppm)
The Model RGO-321 has an additional percent of the lower explosive level (LEL) scale for presenting readings in units of %LEL. The optimal sensor (catalytic combustion or thermal conductivity) is automatically selected for highest accuracy and a full range (0.005 to 100%) %GAS display. Oxygen in ambient air is displayed with 0.1% resolution over a 0 to 40% range with low and high alarm levels set at 19.5% and 23%, respectively.
The detector comes with standard 6 inch fiberglass probe connected to a dust and water block filter on a 5 foot straight hose, a manual, a laminated short guide to operation, a set of batteries, and a shoulder strap. Also included is:
Automatic Calibration (A-CAL TM)
Automatic calibration is a standard feature built into all Gas-Ranger 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 I, Div. 1, Groups A, B, C, and D atmospheres.
Options
-
Docking Calibration (D-CAL) - An optional system for large users offers calibration at docking stations. Calibration data, sensor sensitivities, and usage time are centrally available to help manage risk. Faxes reminding users of due or overdue calibrations are sent automatically.
-
Bar Hole Probes - clear plastic, fiberglass, and stainless steel long probes for underground leak location.
-
Surface Vacuum Probe - for surface surveys (see picture below).
-
Instrument Case - for storage of detector and accessories.
Gas-Rangers Come In Several Models Specifically Designed For Detecting:
