Review on 🌡️ DLG DI-517 Digital HVAC Refrigeration Manifold Gauge with 2 Clamp-on Temperature Probes by David Berry

UPDATE: unused for 10 months. Used twice this year and the distributor fell apart. Doesn't read properly, won't turn off and won't turn on. In total about 12 units were used in 2 years. Back to the 12 year old collector's set and calculator! After disassembling the case I found that the plastic screws were simply broken and the unit would not work unless the front was attached to the back. <><> Here is the original review: Used on three systems. Facilitates diagnosis, verification of hypothermia and overheating. Used in a heat pump system in winter and worked great! Should have bought earlier. Strikes with three devices and manual counting. The quality seems good and the two sensors are fine. I wish Type K was better but it worked. Highly recommended. The price is good and the functionality is fantastic. (Fuck lifetime!)
