Pyrometer question

I have the EVs gauges and my only my pyro has some condensation building up on the inside of the glass. Is this normal or something I should worry about?

How long have you had them? Is the condensation always present, or only under specific circumstances (like leaving a cool garage and heading into a humid day)?

The EV2 circuit board is conformally coated, so condensation is unlikely to harm it, but I'm surprised it is happening. We ran a bunch of temp/humidity testing on this series and did not experience any condensation.

I used to live in Eastern NC (Greenville), so I know how humid it can get there!

I think I have had them for about 3 or 4 months now. I first noticed it when my lights turned on. Whenever I hear my lights click on I always look at my gauges for some reason!! When I looked at my EGT gauge it looked blurry. At a stop light I looked closer and the inside glass had condensation it. A majority of it was in the middle but enough was in there to make the numbers fuzzy. So I gues it starts in the late afternoon. I wish it was a garage to outdoor thing but I dont have a garage!!!! I looked at it today and it has water stains on the inside. Since it was put through the above tests, could it be just an issue with my gauge? Thanks.

NC humidity is the worst!!

Sounds like the moisture seal is compromised

If it has the stepper motors in the gauge, movement is normal when the key is cycled on.

Just to clarify which series of gauge we're talking about - is the lens completely flat or slightly curved (convex)?

Thanks,

Convex. (slightly curved) Original post was corrected, they are the basic EV's not the 2's.

Hey Q don't feel alone in this. Noticed a while back one of my EVs was foggy on the inside. I remember the weather outside was rainy, and I had the AC on low

It only happened that one time, nothing to get me all tore up about lol

Moisture causes corrosion and makes glass look like poo when you cant clean it....
