Static Pressure Dead Weight Tester
Model No.︰BL508
Brand Name︰Baluntech
Country of Origin︰China
Unit Price︰-
Minimum Order︰1 pc
Product Description
The model BL508 static pressure deadweight tester ideal primary standard for defining the static pressure up to 60MPa. Piston gauges are used as the basic primary standards and its principle is accepted all over the world for the most accurate pressure measurements. No other piece of equipment for pressure measurement can match the stability, repeatability and accuracy of the piston gauge.
Specification
|
Uncertainty |
When use one of two piston gauges, uncertainty is 0.01%RD; When test static pressure, uncertainty is (2Pa + 5x10-7*P + 1x10-4*△P), P= Static Pressure Pa, △P =DP |
