CGC-301三合一气体检测仪

Three-In-One, Fast, and Accurate

These multifunctional detectors, developed with support from the Gas Research Institute (GRI), combine previously separate instruments into one small, lightweight package at a fraction of the total cost. Two types of natural gas sensors, an electrochemical carbon monoxide (CO) sensor, a built-in pump and microprocessor control provides accurate and fast gas and CO readings. The Gas-Sentry is used for leak location, bar holing, outdoor / indoor differential CO readings, and flue gas tests. Now you can carry one detector and do the whole job both indoors and outdoors.

The model CGC-311 displays all gas readings as %GAS while the Model CGC-301 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 (0.03 to 100%). A fast TRACK GAS scale helps locate gas leaks quickly. CO in flue gas and in ambient air is measured with 5ppm resolution (1 ppm resolution is optional) and with specificity when the detector is used with the external interference filter.

The detector comes with a standard 12 inch two piece probe, a metal telescoping flue probe with refillable interference filter, a manual, a laminated short guide to operation, a set of batteries, a carryall with pouch for probes, 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.

Extended Duty Flue Probe - for flue gas sampling lasting longer than 5 minutes such as during burner adjustment.

Bar Hole Probes - clear plastic, fiberglass, and stainless steel long probes for underground leak location.

Instrument Case - for storage of detector and accessories.
