Absolute Pressure Gauge

Absolute pressure gauge countries have clear regulations and indicators. In simple terms, there are two aspects: no grease products can be touched during production parts to assembly verification, and the dial has a red oil-free mark. The safety of the absolute pressure gauge depends mainly on the entire production process of the manufacturer, and whether it is strictly in accordance with the national regulations. At present, many manufacturers use the general pressure gauge as carbon dioxide for cleaning and use it as an absolute pressure gauge. This situation is very likely to cause a safety accident. The screws on the back of the absolute pressure case must not be loose.
