4. Product Features
The Xetron DMG-10X offers several advanced features for HVAC professionals:
- Digital Precision: Provides accurate pressure, temperature, and vacuum measurements.
- Bluetooth Connectivity: Seamless integration with a dedicated mobile application for real-time data viewing and intelligent analysis.
- OTA Firmware Upgrade: Supports Over-The-Air firmware updates for continuous improvement and new features.
- Built-in Temperature Compensation: Reduces measurement errors for enhanced accuracy.
- Extensive Refrigerant Database: Supports 18 customizable refrigerant combinations from over 141 refrigerants, continuously updated and compliant with NIST standards. This offers significantly more flexibility compared to traditional mechanical gauges that support only 1 or 2 refrigerant types.
- Thick Film Ceramics MEMS Sensor: Ensures reliable and stable pressure sensing, offering superior durability compared to mechanical shrapnel structures prone to external force damage.
- Clear Display: The device and app clearly display minimum, maximum, average pressure, high/low temperature, EV, CO, subcooling (SC), and superheat (SH) values, even in varying light conditions.
- Data Logging: Local data storage with a capacity of up to 3000 points. Data can be easily analyzed and exported. The recording interval is flexible.
- Vacuum Test Function: Features a parallel display of vacuum values and a progress bar, along with a built-in timer for convenient vacuum duration judgment.
- Hold Pressure Test: Utilizes temperature compensation for more accurate hold pressure test results and provides automatic analysis during the pressure maintenance process.
