FAQs

Is this gauge suitable for outdoor HVAC units?

No, this gauge is specifically designed for dry, indoor installations.

What is the accuracy class of this gauge?

This model has an accuracy class of 1.6.

Can I mount this gauge on a panel?

Yes, this model features a bezel and is designed to support panel mounting.

What connection type does it use?

It utilizes a 3/8 BSP back entry connection.

What pressure ranges does this model cover?

This specific model covers 0 to 10 Bar and corresponding PSI ranges.

Is the casing resistant to corrosion?

The black steel case is durable for standard indoor use, but should be kept away from corrosive environments and high humidity.

Troubleshooting

Needle not returning to zero

Check if the system is fully depressurized; if the needle remains off-center while isolated, the internal mechanism may be damaged.

Leaking at connection point

Verify that the 3/8 BSP thread is correctly seated and that sufficient thread sealant or tape was applied during installation.

Unclear dial readings

Ensure the front cover is clean and free of dust; if moisture is trapped behind the glass, the environment is too humid for this dry-use model.

Pros and Cons

Pros

  • High accuracy class of 1.6
  • Easy-to-read 100mm dial face
  • Dual scale (Bar and PSI) for global compatibility
  • Durable steel casing
  • Flexible mounting options including panel integration

Cons

  • Not suitable for outdoor use
  • Must be kept in dry environments
  • Specific to non-corrosive media applications

Setup, Compatibility & Care

To install the 34/745/0 gauge, ensure the system pressure is fully depressurized before making any connections. The 3/8 BSP thread should be sealed using appropriate thread sealant or PTFE tape to prevent leaks. When panel mounting, ensure the hole cut-out matches the bezel diameter to allow for a secure flush fit. To maintain the accuracy of the device, avoid over-pressurizing the gauge beyond its 10 Bar limit, and periodically wipe the dial cover with a dry, soft cloth. Avoid using harsh chemical cleaners, as these may cloud the dial face or damage the black steel casing finish.
