Frequently Asked Questions:
I received the Visgage with a bubble in the reference tube is that okay?
Yes, the bubble has been installed at the factory to allow for expansion.
What is the accuracy of the Visgage?
Proficient operators can get accuracies of 95% or better.
How often does the Visgage need to be calibrated?
The Visgage can remain in calibration for years or even decades depending on how it is handled. We recommend that you periodically test the accuracy of the Visgage with an oil of known viscosity that is near the mid-range of the lower scale.
I dropped my Visgage and it will no longer work properly. Do I need to purchase a new Visgage?
Visgages can be repaired at the factory. They will function like a new Visgage after the repairs are completed.
I broke the plunger tube on my Visgage. Can I buy parts for the plunger?
We do not sell parts for the Visgage since they must be re-calibrated so that the readings are accurate. The glass tubes can vary and they must be matched at the factory.
Can I check fire resistant hydraulic fluids (Water Glycol) with the Visgage?
Yes, we manufacture special Water Glycol Visgages. We install the specific Water Glycol you wish to test in the reference tube and you compare directly against this standard.
Does the Visgage meet or follow any National Standards?
There are no National Standards that govern the operation of the Visgage. The Visgage is user dependent and quality results are obtained by proficient use.
Can I draw hot oil into the Visgage directly from the crankcase or reservoir?
Oil must be cooled in a separate container before drawing it into the Visgage. The glass is shock resistant but introducing hot oil can break the plunger tube.
