Construction: T he refrigeration pressure gauge is built with a metal interface that adheres to industry standards for durability and resistance. It features a foldable hanging hook for easy transport and storage, and a built-in brass valve with a spherical structure for superior sealing performance. Advanced Stability: Our vacuum pressure manifold tester meter is equipped with a high-stability chip, featuring a 32-bit digital processing unit and a high-precision data acquisition unit, ensuring stable and accurate pressure measurements crucial for reliable diagnostics. Dual Pressure Testing : The refrigeration HVAC temperature tester offers real-time vacuum and pressure readings, providing a reliable basis for assessing the operational status of refrigeration systems. This dual functionality makes it an essential tool for maintenance professionals. Versatile Refrigerant Compatibility: The manifold gauge meter includes built-in data for 92 types of refrigerants and features powerful computational capabilities, allowing for easy switching between common refrigerants. This versatility, combined with an intelligent diagnostic system, simplifies the identification of system faults and records leak times and rates for efficient operation. Optimal Refrigeration Efficiency: The electronic air-conditioning refrigerant fluoride meter displays evaporation and condensation temperatures, indicating the refrigeration system's efficiency. Higher subcooling indicates better refrigeration capacity, while higher superheat can determine the degree of expansion valve opening, crucial for optimizing refrigerant charge levels.
