One other important function of these gas actuated temperature gauges is installing in a remote place and reading conveniently at the desired place where its case is fixed, which means all dials on a single panel for easy visual comparison.

Per your choice, consistent 2% or even 1% accuracy across the full span can be guaranteed on InstruMate linear dial. This gas actuated thermometer model 422 covers all standard temperature ranges.

Model 422 is fillable for applications with extreme vibrations. Silicon oil is advised if instrument needs to be filled, unless for food industry you will need to use food compatible oil.
