About This 【Integrated Refrigeration Testing】 This digital manifold gauge features four functions: dual-temperature and dual-pressure measurement, refrigerant charging, vacuum operation, and pressure leak testing. It automatically calculates subcooling and superheat, and records the duration and rate of leaks in real time. As a professional auxiliary instrument for the installation, inspection, and maintenance of refrigeration equipment such as air conditioners and cold storage units, it provides a one-stop solution for various refrigeration maintenance scenarios. 【High-Precision Digital Measurement】 The digital gauge hvac pressure measurement range is 0–6000 kPa, vacuum measurement range is –101 to 0 kPa, and temperature measurement range is –30 to 125°C. Measurement accuracy reaches ±0.5% FS, with a resolution as high as 1 kPa. It features a large backlit LCD screen that supports automatic switching between multiple pressure units (kPa/MPa/bar/PSI/inHg) and one-touch conversion between °C and °F, ensuring clear readings even in low-light environments. 【Compatible with 92 Refrigerants】 It features a built-in database of pressure-evaporation temperature data for 92 refrigerants compliant with U.S. NIST standards, comprehensively covering common refrigerants such as R134A, R1234yf, R744 (CO2), and R290. It automatically matches the corresponding saturated temperature for each refrigerant without the need for manual calculations. This ac manifold gauge meets the refrigerant testing needs of various refrigeration equipment, significantly improving maintenance efficiency. 【Rugged, Durable, and Portable Design】 Made of high-strength engineering plastic and non-slip silicone, the refrigerant gauge is shockproof, wear-resistant and comfortable to hold. Digital hvac gauge features a standard 1/4-inch connection and durable valve switch for excellent versatility. Compact at 170×110×50mm and only 950g, it runs on 4 AA batteries for easy portability in on-site work. The standard hose supports up to 600 PSI, with a max working pressure of 10 MPa and reliable overpressure protection. 【Three Years Warranty】For any quality problems. If LM120 has any defect, we will provide new replacement or solutions for our customers until satisfaction without delay, and provides lifetime technical support. For any needs, you are warmly welcomed to contact us and we will get back to you ASAP within 24 hours.
