TESTIMONIAL:

"I've had an opportunity to check the use and accuracy of the GR-100 refractometer I ordered and found it to be easy to use and read, and it works exactly as it is designed to. The price is so much better than the electrical/digital models I saw everywhere else that I feel you're offering this device at an excellent price, especially since it gives just as accurate a reading as the digital models.

I'd had the glycerine/water mixture drained and then refilled with new by a regular fire sprinkler suppression service. I asked for and watched as they gave me a direct sample of the fluid they pumped back into the pipes. I also asked for and saw the reading from their digital device. I kept a small bottle of this sample, and after the technician had gone, I used your device to check the glycerine/water balance. As I said, what I viewed through your refractometer was a perfect match for the reading on the technician's device, so I'm confident that the unit you sent me is accurate.

In addition to the attractive price, I like the fact that this is NOT a digital device. Since all the parts are "static," so to speak, and the installed prism will not change over time, I feel confident that I can put this unit away, bring it out to use in a year or so, and it still will give readings with the same accuracy as it did yesterday. Perfect for the home consumer to check his own system without having to pay a service to come out and do it.

So, thanks for a good product at an excellent price."
