Why is Auto Digital Refrigerant Manifold Gauge needed?

Nowadays, the technology used in auto air conditioners is more and more advanced, but its basic refrigeration principle has not changed, that is, the compressed refrigerant absorbs a large amount of heat energy through rapid volume expansion at the moment of pressure release. This is the same as the working principle of indoor air conditioners, but because the working conditions of auto air conditioners are more complex and severe (bumps, high temperatures, and frequent switching) compared with indoor fixed air conditioners, refrigerant leakage is prone to occur. Repairs and maintenance are also more frequent.

Refrigerant Manifold Gauge also known as refrigerant pressure gauge or fluoride gauge. It is mainly suitable for air extraction and pressurization in refrigeration maintenance, for filling air-conditioning refrigerant, and displaying real-time pressure.

With the continuous innovation of refrigeration technology, with the new device of the auto digital refrigerant manifold gauge, users will be able to process all measurements on the auto air conditioner refrigeration system and heat pump faster, more reliably and more flexibly than ever before, helping users to better understand the auto air conditioner system operation, quickly debug or solve system failure problems.

With intelligent professional measurement technology and detailed display interface, the auto digital refrigerant manifold gauge has become a reliable partner for debugging, repairing and maintaining refrigeration, air conditioner systems and heat pumps.

Evaporating Pressure and Temperature Measurement

Measure the maximum pressure when the refrigerant changes from liquid to gas, and the minimum temperature when the liquid changes to gas (the lower the evaporating pressure, the lower the evaporating temperature, the higher the refrigeration cycle efficiency, and the greater the refrigeration capacity).

Condensing Pressure and Temperature Measurement

Measure the minimum pressure when the refrigerant changes from gas to liquid, and the maximum temperature when the gas changes to liquid (the lower the condensing pressure, the lower the condensing temperature, the higher the refrigeration cycle efficiency, and the greater the refrigeration capacity).

What good is a cheap inaccurate tool

What good is a cheap inaccurate tool
I used this tool maybe three times and at forst I thought it was great but it took me hours to charge a system because the pressures never stabilized. Then I saw the unit was drifting on its own. Id zero it out and watch the pressures creep. The lines were open to the air so theres no reason for it to show any other than the zeroed 0psi. But it kept going up and down in pressure with it disconnected. Then one of the temp sensors clamp exploded with the set hanging in the shop about a week later. I was outside the month return policy so I have an expensive useless tool. I swear these are all back door rejects. Do not buy. Youll be sorry.
