Measuring principle:

Electrochemical (EC): for toxic gases and oxygen

Catalytic combustion (CC): for flammable gases and vapors (up to 100%LEL)

Infrared (IR): for flammable gases and vapors and carbon dioxide

Measuring ranges: sensor dependent

Response time: sensor dependent

Expected average life of the sensor: sensor dependent

Measuring gas supply: via diffusion mode

Display: illuminated LCD full graphics display, automatic size setting for optimum reading, displays the battery capacity, gas concentration as current value and peak value

Alerting: depending on the gas type 3 or 2 momentary value and 2 exposure level alarms, battery alarm with visual and acoustical signaling as well as display on the screen, color of the display depending on the alarm state (orange/red).

Horn: 103 dB(A) (can be reduced to 90 dB(A))

Zero point and sensitivity adjustment: manual or automatic with an adjustment program, if necessary, test gas supply via the “SMART CAP” with 0.5...0.6slpm
