Description
Specifications

The Gas Tracer is RKI’s smallest personal 4 sensor monitor with a built in sample pump.

Weighing only 12.3 ounces, it has many features which set the Gas Tracer apart from the competition. For example, it can monitor the standard gas safety hazards for gas/pipeline operations, (LEL combustibles, Oxygen content, and Carbon Monoxide),and it also has a high-sensitivity ppm CH4 leak tracker mode which reads down to 10 ppm. It can also measure 100% volume Methane and dynamically display either % LEL, or % volume with its auto-ranging ability. The Gas Tracer is excellent for gas line purge testing and detection of small gas leaks.

The Gas Tracer’s large LCD display shows all gas readings, battery level, current time, and will automatically backlight in alarm conditions. Other standard mode alarm types include vibration, visual, and audible alarms that can be set to latching or non-latching. Controlled by a microprocessor, the Gas Tracer continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors. The Gas Tracer can operate on either a Li-Ion battery pack or an alkaline battery pack. The batteries are simple to replace requiring no tools to access the removable battery compartment or pack.

Calibration and bump test intervals and reminders are user adjustable and can be set to either go into alarm or to lock the user out of normal measurement mode once a calibration period has expired. Calibrations can be performed automatically or individually in single calibration mode. The Gas Tracer is also compatible with the economical SDM-2012 single channel calibration station.
