Review: Works really well and has a lot of features for the DIY A/C work - This is actually a DUOYI model Y522A unit. Not sure why they blurred the labeling out in their pictures, but whatever. The main point is this is a very affordable digital gauge unit with a lot of features for the Do-It-Yourself guy who wants to work on his own home A/C. Like most of the other reviewers, I agree the hose set that comes with the kit is cheap leaky junk, but you can probably fix the leakage with some good quality seals for the ends. However, I didn't want to take the chance so I bought a really nice Uniweld EZ3HS 36 inch low-loss hose set and it worked beautifully. The only quirk I've found was that every once in a while, the gauge set would zero out the pressure readings all by itself. It was annoying, but all I did was turn the unit off and back on and the absolute pressure gauges usually showed close to what it's supposed to be. Luckily for me, I have mini-splits with electronic valves so I just charged my systems with amount listed on the labels and don't really have to use the pressures like with fixed orifice or TXV systems. The ball shutoff valves are an improvement from their previous style valves and the sight glass is also very useful so that you can see the liquid and know when to pause and when to continue when charging the low side so you're not feeding straight liquid with the compressor running. These units are great for DIY and are super budget friendly, but definitely not for professional use. If you're looking for professional grade equipment, you wouldn't be doing it on desertcart, right? LoL
Review: Me gusta el equipo pero no se por que se descalibra a cada rato eso no lo hace confiable - Esta muy bonito, tiene buena caja de herramientas pero no es confiable las medidas que marca, ya que al desconectar el equipo de refrigeración de vería regresar a cero y no lo hace sigue marcando

## Features

- Suitable for All Refrigeration Equipment & Detects 93 Refrigerants & Data Partition 3.5" LCD Display HVAC gauges can test automobile air conditioning, household air conditioning, refrigeration equipment, cold storage and other refrigeration equipment. Digital manifold gauge set built in 93 refrigerant pressure and temperature database so that can detect 93 kinds of refrigerants. Test data is divided into areas on the 3.5-inch large backlit LCD display, so that you can read the data at a glance.
- Upgraded V-shaped Valve Switch Compared with refrigerant gauge hvac using ordinary knob valve,our digital refrigerant gauges adopt upgraded V-shaped valves, which are full-bore ball valves, with low fluid resistance, and control the refrigerant filling amount more accurately.You only need to turn 90 to easily open or close the valve and save operating time.V-shaped valve has two sealing surfaces using advanced material,which is resistant to corrosion and wear, and can achieve complete sealing.
- Evaporation/Condensation Pressure and Temp. Test & Pressure Leakage Test HVAC manifold can perform refrigeration system pressure and temp. tests to determine refrigeration capacity. The lower the evaporation/condensation pressure and temperature, the higher the efficiency of the refrigeration cycle and the greater the refrigeration capacity. HVAC gauges calculates the pressure difference between the initial test pressure and the second test pressure to determine whether refrigerant is leaking.
- Overheat/Subcooling Test&High/Low Pressure Temp. Test&Vacuum Operation When temperature clamps connect to AC pipe,it will read superheat and supercooling automatically.The higher the superheat, the smaller the expansion valve opening (less refrigerant) can be determined.Refrigerant temp. in the high/low pressure pipes can also be tested. HVAC gauges can be connected to a vacuum pump for vacuum operation, which makes the refrigerant filled with higher purity, the better the refrigeration effect.
- Multiple Unit&32-bit Digital Processing Unit&Observation Window&Non-slip Silicone Design HVAC manifold supports multiple pressure&temperature unit switches, such as kPa,MPa,bar,InHg,PSI,Celsius/Fahrenheit.Built-in 32-bit digital processing unit, more stable data processing.Viewing window allows you to observe refrigerant charging state directly.Silicone non-slip design prevents slip and fall. Digital manifold gauge set comes with temperature clips and refrigerant hoses(burst pressure:3000 PSI).
