Good Digital Panel Meter

Review by Robert Clappier on 3/7/2018

I was put off by this Digital Panel Meter because there doesn't seem to be a proper data sheet for it anywhere on the internet. I am an electrical engineer and use data sheets for all initial selections and then detailed design. But the meter was so close to what I needed for this OEM product that I bought it anyway. In early lab tests it seems to work perfectly and is accurate against my best lab digital voltmeter. The only reason I gave it 4 stars instead of 5 is that I have not used it enough to know how it will work in day to day operation.

I have been using these meters for 7 Years both Red and Blue in different voltages and have purchased close to 200 of these meters with one or two failures, and that was due to a damaged shipping box. I'm a happy camper.
