Precision Pressure Gauge YB-150

Precision pressure gauges are primarily used to calibrate industrial general-purpose pressure gauges and can also be employed for online measurement of high-precision working medium pressure. Precision pressure gauges are a commonly used metrological standard instrument in fields related to pressure measurement testing, inspection calibration, and verification, such as pressure parameter assessment.

Originally referred to as standard pressure gauges, precision pressure gauges have a long production history in China, with a complete series and comprehensive specifications and models. They comply with the national standard GB-1227 and the verification regulation JJG-49. Their simple structure, stable performance, intuitive and vivid indication, high cost-effectiveness, and complete series make them widely applicable in industries such as petroleum and chemical, in production and scientific experimentation processes, and at various levels of pressure value transmission and metrological verification departments. 

Accuracy classes of precision pressure gauges: This instrument is a high-precision pressure measurement device with a spring tube as the measuring element, classified under spring tube pressure gauges. It is a high-precision standard spring tube pressure gauge. Its accuracy classes are divided into 0.4, 0.25, 0.16, and 0.1. Gauges of 0.4 and 0.25 classes are often referred to as high-precision pressure gauges, while those with 0.16 and 0.1 accuracy are commonly called high-precision precision pressure gauges or high-accuracy pressure gauges.
