MODELS RGI-201 & RGI-211
The Models RGI-201 and RGI-211 display %GAS and after a preset time will display peak and sustained bar-hole gas readings. The RGI-201 also displays %LEL.
Accurate, Rugged and "Smart" Gas Detectors for Utilities
The all-weather, Gas-Ranger detectors, specifically designed for gas and other utility personnel, can be used to track gas leaks, bar-hole, and to monitor ambient air for natural gas and methane. Two types of natural gas sensors, a built-in 2 liter/minute pump, and microprocessor control provides accurate and fast gas readings. The Gas-Ranger is used for bar holing and quick leak location. 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. The unit alerts aubibly and visually (e.g. GAS) when levels of gas are detected over the 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 RGI-211 displays all gas readings as %GAS while the Model RGI-201 has an additional percent of the lower explosive level (LEL) scale for presenting readings in units of %LEL. Both models automatically select the optimal sensor (catalytic combustion or thermal conductivity) for highest accuracy and read percent gas over the full range (0.005 to 100%).
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:
Gas-Ranger's high speed internal pump
is ideal for leak classification.
