TRZ Hamh Optics&Tools First Impressions

Using for my Pacman frog.

Plus it is super easy to use and clean. Very quick to calibrate and to use. I bought this refractometer as a more accurate option for salinity than a hydrometer. It works, we'll i assume it does as i have nothing to compare it to. I think those reviews just didn't know how to use it properly. Do not spend money on calibration fluid to calibrate this meter. I've tried several different refractometers now and they are mostly the same.

TRZ Hamh Optics&Tools Final Thoughts

Be well my friend.

I found mine was calibrated out of the box. Good quality and simple to use refractometer. I was surprise that the product was really cheap compare to the other ones. Works well on my Saltwater Aquarium. Don't care much for having to post a review in order to activate warranty. Compare it with the refractometer and adjust the refractometer so that it matches. When I compared it to what my local pet store was reading my water at it was dead on.
