Product Features
Compressor Test Mode：The Compressor Test Mode comprehensively monitors real-time high- and low-side pressures of the refrigeration system and automatically matches the corresponding refrigerant evaporation saturation temperature and condensation saturation temperature. Combined with the measured evaporator line temperature, condenser line temperature, and compressor operating temperature, the system automatically calculates critical parameters such as superheat and subcooling, helping technicians visually evaluate compressor operating conditions and refrigeration system performance.
Cooling Mode：Real-time measurement and display of low-side pressure, high-side pressure, refrigerant evaporation saturation temperature, refrigerant condensation saturation temperature, actual evaporator line temperature, actual condenser line temperature, superheat, and subcooling—providing comprehensive data support for refrigeration system diagnosis and maintenance.
The Vacuuming Mode:The Vacuuming Mode can measure and display vacuum pressure, water evaporation temperature, ambient temperature, and temperature difference. This mode is commonly used during vacuuming to help technicians monitor and evaluate the current vacuum condition.
Pressure Holding Test Mode:By comparing the initial test pressure with the secondary test pressure, the LM180 calculates the pressure difference to help determine whether there is a potential refrigerant leak. This function is commonly used to evaluate the sealing performance and leak condition of automotive A/C and refrigeration systems.
Intelligent Control System:The LM180 features an intelligent menu-driven operating system with clear and intuitive test result displays. Its simplified operating interface makes traditional refrigeration system testing easier and more efficient, allowing technicians to complete diagnostic and maintenance tasks with less effort.
Built-in Database of 95 Refrigerants：The system includes data for 95 commonly used refrigerants, eliminating the need for manual saturation temperature lookups and calculations. Superheat and subcooling values can be automatically calculated and displayed on the same screen, allowing technicians to clearly compare high- and low-side system data at a glance.
Multiple Unit Conversion：Supports automatic conversion between multiple pressure units and allows quick switching between °C/°F temperature units and multiple pressure units, making the device adaptable to different working environments and user preferences.
4.3-Inch Large Dot-Matrix Display：The LM180 is equipped with a 4.3-inch 320 × 240 dot-matrix display with a backlight for improved visibility, even in low-light working environments. All functions can be operated directly through the control panel buttons. The clear interface and easy-to-read data display help technicians improve diagnostic efficiency and reduce operating complexity.
Multi-Language Support：The LM180 supports 8 languages: English, Russian, German, Italian, Korean, Dutch, Chinese, and Japanese. Language packages can also be upgraded according to customized user requirements.
Unique Product Design:
1.Foldable Hanging Hook
The foldable hook allows the LM180 to be conveniently hung on the vehicle hood during operation. It can be folded away when not in use for easier storage and improved portability.
2.High- and Low-Pressure Valves
The high- and low-pressure valves feature intuitive arrow indicators, making valve operation status easier to identify. Compared with conventional rotary valve designs, the arrow-marked design provides clearer visual guidance and simplifies operation.
3.Dual Refrigerant Sight Glasses
Dual visual sight glasses allow users to observe the refrigerant flow and charging condition during system service.
4.TPU Protective Side Handles
The side handles are made of durable TPU material, providing corrosion resistance, a comfortable grip, and improved portability for easy carrying and movement.
