◆ Ultra low pressure gauge ◆
● Model : P423
● Service intended :
P423 series are designed to measure ultra low, vacuum or compound pressure. These models have a stainless steel measuring element which consists of two formed diaphragms and diaphragms are welded together.
● Nominal diameter : 100 mm
● Accuracy : ±1.6% of full scale
● Scale range (kPa, mbar) :
-1 ~ 0 to -0.2 ~ 0 kPa
-0.1 ~ 0.1 to -0.5 ~ 0.5 kPa
0 ~ 0.2 to 0 ~ 1 kPa
● Working pressure :
- Steady pressure : 75% of full scale
- Over range protection : 130% of full scale
● Working temperature :
