Hydrometer Discrepancy

[NTXBrauer]

I recently found a deal on CL and picked up a starter kit, to add some additional brewing equipment to the arsenal. In doing so, I added a 2nd hydrometer that I can take SG readings with.

Just now, I took a SG reading and have 2 varying results from the same beer sample. One hydrometer read 1.006 and the other 1.010. The target FG for the Belgian Blond I am working on is 1.008, so I am definitely in the range. My gut is telling me to go with the hydrometer made in Germany vs. the no-name one I picked up in the kit.

Do any of you take SG readings with multiple hydrometers? What type of delta have you experienced?

Have you checked them against plain water?

Good call. Just checked the 2 against each other, and the kit hydrometer is 1.000....My go-to 13 year old one appears now to be a bit off at .997 with a delta of .003. This difference is representative of the delta in the SG I just got on my Blond. I will have to look into the reliable lifespan on a hydrometer.
