Class 1 3.5″ 0-30 Test Vacuum

Description

A Class 1 3.5″ 0-30 test vacuum is a pressure gauge specifically designed to measure vacuum pressure, typically used in industrial and firefighting applications. Here’s a breakdown of the terms:

• Class 1: This refers to the accuracy of the gauge. Class 1 gauges are highly accurate, with a tolerance of +/- 1% of full scale.
• 3.5″: This refers to the diameter of the gauge face.
• 0-30: This indicates the pressure range the gauge can measure, which in this case is from 0 (perfect vacuum) to 30 inches of mercury (inHg) of vacuum pressure.
