Product Functions
1. Ac Gas Pressure Gauge features a big artistic screen and batteries with 1 year service life. The gauge has backlight, auto off, low battery indication, overpressure alarm and other functions. It is designed for use in piping system, refrigerated system and other applications.
2.This gauge has no moving parts, has long service life, high precision, good long-term stability.
3.It has pressure and temperature parameters for commonly used refrigerant inside,the measured pressure, condensation temperature and evaporation temperature are very clear to see.
Application Range
The SBF-L-07 digital display double table valve is used for the assembly and maintenance of vacuum refrigeration system. The operator must possess the qualification of the industry and have certain operational experience.
◆ The SBF-L-07 digital display double table valve sets together with the traditional composite table, the temperature measuring instrument and the refrigerant characteristic diagram, and it's available to measure both pressure and temperature.
◆ The SBF-L-07 digital display double table valves are suitable for most non-corrosive refrigerant, water, alcohols. But it is not suitable for the refrigerant containing ammonia.
◆ This product is not suitable for the areas with explosion - proof requirements.
Highlight: Strong, shockproof &corrosion-resistant,Clear and direct reading
