Product Description

Frequently Asked Questions

What is the Preciman absolute vacuum gauge used for?

The Preciman absolute vacuum gauge is used for monitoring vacuum systems in industrial applications that require precise low-pressure measurement. It measures pressures from -1 to 0 bar and is suitable for pneumatic systems, compressors, regulators, and machinery handling fluid or gaseous media that do not clog the connection port or corrode copper alloy.

What are the specifications of the Preciman absolute vacuum gauge D63 -1/+0 bar G1/4?

The Preciman absolute vacuum gauge has a range of -1 to 0 bar, accuracy of ±2.5% of full scale, a 63 mm (2.5 inch) dial, G1/4 connection, green dial color, and a black ABS case. It features a copper-alloy Bourdon tube, brass connection, and snap-in acrylic window. Operating temperature is -20 °C to 60 °C.

Where to buy the Preciman absolute vacuum gauge in Singapore?

You can source the Preciman absolute vacuum gauge through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this SKU 3G-CBM-06298. We provide reliable sourcing for industrial measurement equipment.

How to install the Preciman absolute vacuum gauge?

Install the Preciman absolute vacuum gauge by connecting the G1/4 thread to a compatible port on your vacuum system. Ensure the gauge is mounted vertically for best accuracy. Avoid exceeding the working pressure limits: steady at 3/4 of full scale, fluctuating at 2/3 of full scale. Use thread sealant on the connection to prevent leaks.
