80 mm Precision Vacuum Gauge (Vacuum Meter) 0-1000 mbar Bottom Connection

Designed for precise measurement in refrigeration systems, laboratory equipment and industrial vacuum pumps, the 80 mm Vacuum Gauge (Vacuum Meter) lets you read vacuum and absolute pressure values between 0 and 1000 mbar with high accuracy. With its sturdy bottom-mounted brass connection and durable metal case, it delivers reliable performance in heavy job site and service conditions.

Clearly Readable Dial and Adjustable Reference Pointer

Thanks to its large 80 mm dial diameter and distinct black numerals, it can be read easily from a distance even in dark or confined spaces. The manually adjustable red reference pointer (set pointer) on the front glass lets you mark your target vacuum value. This way, you can check at a glance whether the system has reached the required vacuum level or whether there is a leak in the system.

Key Technical Features and Equipment

Ideal for industrial and HVAC (Heating, Ventilation and Air Conditioning) applications, this measuring instrument has the following technical details:

• Dial Diameter: 80 mm (large, easy-to-read display)
• Measuring Range: 0 - 1000 mbar (Vacuum / Absolute Pressure)
• Connection Type: Bottom-mounted, corrosion-resistant brass fitting (compatible with standard systems).
• Case Material: Impact-resistant, blue powder-coated metal case and transparent protective glass.
• Indicator Panel: Black main pointer showing the instantaneous value and adjustable red reference pointer for setting a target.
• Applications: Air conditioning and refrigeration systems, vacuum pumps, leak tightness tests and general industrial processes.

Practical Usage Note for Technicians in the Field

Technician's Note: When pulling a vacuum on your system (or pressure testing it with nitrogen), turn the red pointer to your target mbar value to mark it. While the vacuum pump is running, watch the black pointer reach the red pointer. After the process is complete, close the valves and wait for a while; if the black pointer deviates from the red target and moves back, you can easily detect that there is a leak or residual moisture in your system.
