DUOYI DY610 Digital Vacuum Gauge 0 ~75000 microns

Digital vacuum gauge (0 to 75,000 microns) + backlit LCD screen + intelligent refrigerant boiling point detection + real-time measurement of ambient temperature and humidity.

Key Features & Benefits:

High Precision & Stability

Equipped with a Pirani vacuum sensor and a 32-bit digital processor, the DY610 delivers reliable measurements during critical dehydration and evacuation phases.

- Accuracy: (10% of reading + 10 microns) in the 100-1000 micron range - meeting the refrigeration industry's strict deep-vacuum requirements.

Smart Multi-Unit Switching for Global Standards

Supports 11 vacuum units (microns, mTorr, Pa, mbar, inHg, etc.) and C/ F temperature units, making it easy for technicians worldwide to work under diverse conditions.

Multi-Function Integration - One Device, Multiple Uses

Measures vacuum level plus real-time ambient temperature, humidity, and refrigerant boiling point - helping you know exactly when the system is ready for refrigerant charging.

Clear TFT Display with Intelligent Backlight Alert

All critical data shown on one screen for instant readability.

When your target vacuum is reached, the backlight automatically changes color (threshold alert) - no more staring at numbers! Boosts both efficiency and safety.

Rugged & Portable - Professional Industrial Design

Built with high-strength engineering plastic, weighing just 190 g and compact (6.5 × 3.5 × 14.5 cm) - perfect for fieldwork and one-handed operation.

Fast Response & Low Power Consumption

Measurement cycle as fast as 0.5 seconds for real-time feedback.

Powered by 3 AA batteries with long runtime + battery level indicator to avoid unexpected shutdowns.

Safety & Compliance

Certified to GB4793.1 and IEC/EN61010-1 safety standards - ensuring reliable, safe operation even in demanding environments with high voltage or extreme cold.
