Seven Key Advantages of Jingchuang Digital Dual-Gauge Valves
1. Enhanced Accuracy and Intuitive Display
Imported high-precision digital sensors deliver over three times the accuracy of traditional mechanical pressure gauges, providing pressure readings in percentage increments. During pressure maintenance, the system automatically compensates for temperature-induced pressure variations, eliminating complex manual calculations for superior measurement precision.
2. Multi-Functional Efficiency: One gauge replaces multiple functions. Supports DMG-4B = N sets of pressure gauges (one mechanical gauge corresponds to only 2-3 refrigerants) + basic vacuum gauge (DMG-4B can activate vacuum mode).
III. Smart Connectivity, Universal Device Enables real-time data viewing and analysis via network connectivity. Supports online data logging and export via app. Pre-program 18 refrigerants from a library of 140+ options into the device or switch via app anytime. Supports remote firmware upgrades.
IV. Three-Mode Switching
After enabling pressure hold or vacuum modes, freely switch between all three modes during pressure measurement to precisely monitor refrigeration system operation before and after startup.
V. Durable Construction
Impact-resistant aluminum valve body with reinforced housing. MEMS-based thick-film ceramic digital pressure sensor offers over five times greater impact resistance than mechanical diaphragm gauges.
VI. Data Logging for Efficient Fault Monitoring and Analysis (Requires separate purchase)
Enable data logging with configurable recording intervals. Stores up to 3,000 data points over 3,000 hours. Supports automatic data analysis with exportable reports via the app.
VII. Compact Design for Enhanced Portability
The DMG-4B features a compact form factor and comes standard with a tool kit for convenient operation and transport.
