Asbobning texnik xarakteristikalari

1. O’lchash oralig’i:

Aniqlanayotgan element	Yonuvchi gaz aralashmasining tarkibiga qarab elementlar konsentrasiyasini o’lchash oralig’i, mg/l
	Propan – butan - havo	Tabiiy gaz - havo
Natriy Kaliy Litiy Kalsiy	0.005 dan to 50 gacha 0.010 dan to 50 gacha 0.01 dan to 50 gacha 0.014 dan to 50 gacha	0.01 dan to 50 gacha 0.05 dan to 50 gacha 0.05 dan to 50 gacha 0.1 dan to 50 gacha

Konsentrasiyasi o’lchashning quyi chegarasiga yaqin bo’lgan eritmalarni o’lchaganda asbobning strelkasi shkalaning 20 dan kam bo’lmagan bo’lagiga burilishi kerak. Shu holdagina o’lchash natijasi o’rtacha kvadratik cheklanish qiymatining besh baravariga to’g’ri keladi.

2. Asbobning sezgirligi, shkala bo’laklarining soni/(mg/l). Sezgirlik quyidagi formula orqali aniqlanadi bu yerda, - o’lchangan signalning qiymati (shkalaning bo’laklarida), - o’lchanadigan kattalikning qiymati (mg/l)
