Value Digital Micron Gauge VMV-1

The VALUE VMV-1 Digital Vacuum Gauge is a high-precision instrument designed to accurately measure vacuum levels in HVAC and refrigeration systems. Equipped with an advanced Pirani vacuum sensor, it delivers reliable and precise readings across a wide measurement range, making it ideal for professional servicing and maintenance tasks.

The device features a clear digital display that provides real-time monitoring of vacuum conditions in multiple units, including Pa, mBar, mmHg, and microns. Its intelligent alarm system enhances usability by notifying users when the preset vacuum level is reached with a buzzer. Additionally, it alerts users to potential leaks by rapidly buzzing and flashing the backlight if the vacuum level drops below the set threshold.

Designed for convenience and durability, the VMV-1 includes multiple adapters and a standard 1/4″ SAE port for easy connection with HVAC systems. It offers a fast sampling rate of 0.5 seconds and operates efficiently within a temperature range of 0°C to 50°C.

With a long battery life of up to 45 hours and features like automatic power-off and backlight control, the device ensures energy efficiency and extended usability. Packaged in a protective textile case and carton box, it is suitable for both field and workshop use.
