[Built-in 90 Refrigerants] - This digital manifold gauge contains more than 90 refrigerant data, that is, almost all refrigerant types. So please don't worry that the gauge is not suitable for your refrigerant system. [Digital Dual Gauges] - Low pressure is shown on the left and high pressure is shown on the right. The gauge adopts ball valve design and high-precision sensor, which makes the fluoride addition more accurate.[Quality Accessories] - The 1.5m three-color fluoride pipe adopts acid and alkali resistant glue, which is explosion-proof and pressure-resistant, and has good air tightness. Thickened portable outer case can better protect the product. Please notice that two 9V batteries are NOT included in the package. [Multifunction] - 3 working modes: refrigerant pressure mode, vacuum percentage mode, leak detection mode. 5 pressure unit conversions: KPa, Bar, PSI, InHg, KgF/cm².
[Explosion-proof Sight Glass] - Through the high-definition glass window, the flow of refrigerant can be clearly observed, so problems can be found in time, so that problems can be detected in time.
