Review JB INDUSTRIES Analog Micron Vacuum Gauge Purpose Black

The JB DV-21N Analog Micron Vacuum Gauge is a versatile and precise measuring instrument designed for vacuum applications. This gauge features a high-performance analog micron vacuum sensor, which can measure vacuum levels down to a resolution of 1 bar (micron). The sensor is encapsulated in a rugged borosilicate glass housing, ensuring durability and resistance to harsh environments.

The gauge's vacuum range is from 999.9 Torr (absolute) to 10-6 Torr (1 micron), making it suitable for a wide range of vacuum processes. The large, easy-to-read analog dial displays vacuum levels with great accuracy, providing real-time feedback on system performance. The dial is graduated in microns, Torr, and mbar for added versatility.

The JB DV-21N Analog Micron Vacuum Gauge comes with a built-in vacuum pump controller that can be used to operate a rotary vane vacuum pump or a vacuum ejector. The controller can be set to maintain a constant vacuum level, providing automatic vacuum control for your vacuum process. The gauge also includes a manual bleed valve for quick pressure equalization during gauge reading.

The gauge's compact size, measuring only 11.4 x 3.6 x 4.1 inches (29 x 9 x 10.4 cm), makes it easy to install and transport. It is also lightweight, weighing just 1.9 lbs (0.9 kg), making it a convenient choice for use in laboratories, factories, or other industrial settings.

The JB DV-21N Analog Micron Vacuum Gauge is designed for long-term use and features a robust construction that can withstand the rigors of industrial vacuum applications. It is backed by a one-year manufacturer's warranty, ensuring your satisfaction with the product. Overall, this gauge is an essential tool for anyone who requires precise and accurate vacuum measurements in their work.
