Ammonia pressure gauge

The ammonia pressure gauge is an ammonia instrument used to measure the pressure of non corrosive, non crystalline, and solidified ammonia and ammonia liquid media on ordinary carbon steel, alloy structural steel, austenitic stainless steel, and tin lead alloy brazing materials. Mainly suitable for measuring the pressure of ammonia in equipment or other liquids, gases, or mixtures used in the production process of fertilizers.
The ammonia pressure gauge is a type of instrument that can explode when in contact with copper and copper alloys. Therefore, a yellow horizontal line must be marked below the product name on the product dial as a warning. (Quoted from Article 7.1.2 of GB/T9272-1999)

Ammonia Pressure Gauge - Application

The ammonia pressure gauge is mainly suitable for measuring the pressure of ammonia in liquid, gas, or their mixtures during fertilizer production or refrigeration equipment; It can also be used to measure the pressure and vacuum of various non corrosive, non crystalline, and non solidifying media such as ordinary carbon steel and austenitic stainless steel.
