Sounds like something is wrong. Polymer magnets are stronger than ceramic. Not sure why your getting the readings like you are. Are you placing the magnets in the exact same spot? Are the polymers harder to pull apart when they are placed together? I have one of those magnet matchers. I know they are sensitive to where you place your magnet and that to get a good reading they need to placed in the exact same spot. I haven't measured any polymers yet. Let me give it a try and I'll get back with you.

I may be wrong (but I never think I am...lol) but I don't think that matcher is designed for anything much stronger then tjet magnets. I got my brp magnet matcher today. I got a lot of mags not counting the ones in cars. I'm testing and I'm getting some ceramic mags stronger then my polymers is this right? And can you put a poly and a ceramic in a car? If this thing is right, I'm very disappointed in polymer magnets because is not one or two its like 5 or 6. And the $$$$ for polymers iowajeff

You can test stronger magnets with the BRP, You just have to use a spacer to hold them back from the sensor. If you place a magnet that is too strong right up next to the sensor it will become saturated and give you bad readings. The BRP even comes with a small square sleeve that fits over the sensor to hold stronger mags back a little bit.

So what you are saying is that I'm half wrong? I can live with that ;D You can test stronger magnets with the BRP, You just have to use a spacer to hold them back from the sensor. If you place a magnet that is too strong right up next to the sensor it will become saturated and give you bad readings.

I think Jet maybe a little more than half right.I put the sleeve on and the ceramic are still stronger then the polymer, but when I finger test them the polymer are alot stronger. So maybe it's like a apple and orange thing. Or maybe more like an orange and tangerine thing. I,ll just test them separate and not compare them. Thanks everybody for your time:iowajeff

Try using a wood block about an inch thick as a spacer and see if that gives you a reading that you can understand. If not use thinner ot thicker spacers to adjust the distance until you get consistent readings. Then use that spacer on all of the same type of magnets.
I don't know if this will work but it makes sense.

Iowajeff, what magnets are you testing? motor mags or traction mags and what brand of car are you testing? I tested some stock polymer S G+ traction mags and got readings between 1.113 and 1.248. This was with the square sleeve on. If I take it off the sensor saturates and I get a reading of 2.032. I don't have any ceramic mags for the SG+ to test.
I also tested some tyco 440x2 mags just for fun. I had to use the sleeve for these also. They tested between 1.322 and 1.346. I then tested one of BSRT's force magnet for the x2 and it was off the scale.
Like SKR said placement is critical. If you want consistant readings you have to place the mags in the same place every time.

T-jet polys N-0.967 S-1.031 on the sensor. I got JL and super II that test higher. The polys are alot stronger pulling apart with fingers than the ceramics. I just need it for matching so I think it well steal work.

when i check t-jet mags i use a spacer under the mags to center the mags on the sensor. If you just set the mag on top of the box you are checking the top edge not the center of the mag.
