Bayanan samfurin
MP-701 ammonia gas firikwensin ya yi amfani da multi-layers kauri fim masana'antu tsari, a bangarorin biyu na kananan Al2O3 yumbu substrate yin dumama da karfe oxide semiconductor gas layers daban-daban, kunshe a cikin karfe shell. Lokacin da kasancewar gas da aka gano a cikin iska na muhalli yana canzawa, mafi girman taro na gas, mafi girman wutar lantarki na firikwensin. Amfani da kewayawa mai sauƙi zai iya canza wannan canjin gudanarwa zuwa siginar fitarwa daidai da yawan gas.
Sensor siffofin
Wannan samfurin ne m ga ammonia; Tare da amfanin amsa dawowa da sauri, low ikon amfani, ganowa kewaye mai sauki, kyau kwanciyar hankali, dogon rayuwa da sauransu.
Babban aikace-aikace
Ana amfani da shi sosai don gwajin gas na firiji, gwajin zubar da ammonia mai sanyaya da kuma sarrafa iska a masana'antar noma.
