Bosim o'lchagichning eng past aniqlik darajasi 4 ga teng.
Xitoyda umumiy sanoat foydalanish uchun bosim o'lchagichlari to'rtta aniqlik darajasiga bo'linadi, ular JJG52-1999&tekshirish qoidalarida nazarda tutilgan bosim o'lchagichlarining ruxsat etilgan xatolariga mos keladi; Vakuum o'lchagichlar va vakuum o'lchagichlar".
To'rtta aniqlik darajasi: 1-daraja, 1.6-daraja, 2.5-daraja va 4-daraja.
Bosim o'lchagichning yuqori chegarasi:
The size of the upper limit of the pressure gauge is designed according to the size, stiffness and nonlinear conditions of the spring tube. The upper limit of the measurement is 1× 10N, 1.6× 10N, 2.5× 10N, 4× 10N, 6× 10N five series, n is a positive integer, negative integer or zero.
