🔬 Thermco GW2540 Specific Hydrometer Division: Accurate Measurements for Precise Liquid Analysis Review

Not as advertised. Accuracy was zero, 10% element variation is totally unacceptable. I doubt it has been tested to NIST requirements.

This is stupid. I have a craft brewery and need very specific and calibrated final gravity values. This thing is tiny! The idea behind laboratory hydrometers is that they are the same size as traditional hydrometers but have better and clearer spacing between points. It's no different from other $15 hydrometers except it's smaller! What a waste of money. GARBAGE!

I used this hydrometer to measure very heavy sugar water and then alcohol where I needed a high SG range of 1.000 to 1.220 to calculate strength. Works perfectly! The areometer is 11 inches long with a dial length of 5 1/2 inches. The scale division has a very easy to read resolution of 0.002 over the entire range! The numbers on the scale are also large enough to be easy to read. What's really nice is the fact that this hydrometer has been calibrated to equipment traceable to the National…
