Fluke 101 vs AstroAI AM33D

Today we’re going to comopare the Fluke 101 vs AstroAI AM33D. I have both but if I had to choose I would go with the AstroAI mostly because I need to be able to test currency.

Mutli Meter Ranging Measure Current Backlight Build Quality Accuracy Price
AstroAI Manual Yes Yes Very Good Good Higher
Fluke Auto No No Good Good Lower

These are both pretty decent multimeters. To be fair this is kind of an apples and oranges type of comparison though. The AstroAI is manual ranging multimeter and the Fluke is an automatic ranging multimeter. Other than that the next biggest difference between these is the brand. Next would proably be the build quality. There is nothing wrong with the build quality of the AstroAI but the Fluke is better. Probably last is the price. The Fluke is almost four times the price. This was the least expensive AstroAI I could find and also the least expensive Fluke I could find. I could spend a little bit more and get a slightly higher end AstroAI which would be better to compare against the Fluke and it would still be less expensive. Overall it feels like the Fluke should be in a different league.

When I tested these they gave me almost the exact same reading. They both went down to three decimal places when measuring the voltage of a battery. They were almost the same except for the last digit (by about 1 ) which was slightly different depending on how much pressure I applied on the terminals of the battery.

So keep in mind that AstroAI does make an automatic ranging mutimeter which should be less expensive than the Fluke 101. You can’t go wrong with the Fluke but the AstroAI is totally fine too.

NOTE - One huge thing that I didn’t mention above is that the Fluke doesn’t measure current. You can’t really get an amperage reading with it. The AstroAI also has a backlight which is nice.
