10. Specifications
10.1. Sensor
Solid-state ionic conductor with stabilized zirconium oxide electrolyte.
•Temperature:
1000K (727°C)
•Warm-up time:
20 min., full specification after 40 min.
•Calibration interval:
12 months
•Reference gas:
Atmospheric air (20.946 % oxygen)
•Sensor response time:
Less than 50 msec.
•System response time:
Less than 10 sec., depending on flow and measuring gas
hose
•Calibration:
Atmospheric air 20.946 % + up to four optional calibration
gases
10.2. Flow system, MAP Check 900X-1 and MAP Check 900X-2
The measuring gas is supplied continuously by means of an electric pump. The flow system
in MAP Check 900X-1 and MAP Check 900X-2 can avaible with or without bypass flow. A
bypass flow will give a faster response time but will consume more gas.
