LUTIFIX Digital Vacuum Gauge, ±0.2% High-Precision 3' LCD Screen Intelligent HVAC Vacuum Meter with Evacuation Mode, Pressure Leak Test, Support Data Transmissio, 4 Units Switch, Wide Applications

["Real-Time Vacuum Monitoring for HVAC Systems – The LM100 digital vacuum gauge continuously tracks the evacuation process of refrigeration, heat pump, and air conditioning systems. It measures real-time pressure changes, allowing you to accurately assess moisture removal, oil contamination, and non-condensable gas extraction. Designed to work with a vacuum pump and compatible with refrigerant gauge sets, it’s an essential diagnostic tool for system dehumidification and purity verification.","High-Precision Sensor with Automatic Temperature Compensation – Equipped with a sensitive micron vacuum sensor that detects minute pressure fluctuations instantly. Measurement range: 0–2000 mbar, accuracy ±0.2% or ±6 mbar, and resolutions down to 0.1 mbar / 0.1 hPa / 0.01 Torr / 0.01 inHg. The built-in temperature sensor and microprocessor automatically compensate for ambient temperature changes, ensuring reliable, precise readings across a wide range of field conditions.","Two Dedicated Detection Modes for Comprehensive Analysis – Vacuum Pumping Mode: displays real-time vacuum pressure, water evaporation temperature, ambient temperature, and temperature differential – ideal for judging system evacuation status. Pressure Holding Mode: calculates pressure difference between initial and secondary test readings, helping you detect refrigerant leaks and verify system sealing integrity without guesswork.","Multi-Unit Switching & Easy-Read Backlit Display – Supports 4 pressure units (mbar, hPa, Torr, inHg) and 3 temperature units (°F, °C, K) for direct data output – no conversion needed. The 3-inch backlit LCD screen provides clear, glare-free readings even in dim mechanical rooms or outdoor environments, making data logging fast and error-free.","Foldable Hook & Rugged ABS Construction – Features a heavy-duty foldable hook on the back, allowing hands-free operation during long evacuation tasks. Made from impact-resistant, dust-proof ABS material, this micron gauge withstands tough job site drops and debris. Compact and durable, it’s built for daily field use by HVAC technicians, automotive specialists, lab researchers, and industrial professionals."]
