Type designations: G999E (with slot for a fourth electrochemical sensor EC)
Measuring principle:
Electrochemical (EC): for toxic gases and oxygen
Photoionization (PID): for toxic flammable gases and vapors
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 the diffusion opening while the pump is switched off or
via the suction opening during the pump operation (sensor cover closed)
Pump capacity: 0,5…0,6slpm @0kPa / 0,30slpm @-4kPa / 0,0slpm@-10kPa max. 100 m hose length (depending on the measuring gas and hose)
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).
