XC 341
Carbon Monoxide Detector

FEATURES

Large LCD display : Large LCD display with 12mm high charactor provides easy reading of gas concentration.

Compact size / light weight/ simple operation : Instrument weighs only approx. 230g and one-handed operation can be performed.

Distinctive Alarm at 2 presetting levels : When gas concentration exceeds alarm level, alarm with flashing lamp and audiable buzzer is activated lamp flashes with long-term intermittent buzzer sound at 150 ppm lower. Presetting level and lamp flashes with short-term intermittent buzzer sound at 150 ppm upper presetting level.

Low power consumption design : Over 200 hours continuous operation with R6 (size AA) dry cell batteries is performed.

Low battery condition alarm function : When battery voltage gets to unusable level, low battery alarm is activated even while measurement is performed. To avoid mis-measurement, battery alarm is activated before instrument is no longer functional.

High selectivity to interference gases : Controlled potential electrolysis sensor provides high selectivity to interference gases.

Optional sampling set : Instrument also can be used as suction type detector with an optional sampling set.
