Highly recommend for DIY mechanics! Review: A good tester - Used it to test my antifreeze. Checked the calibration and it was spot on. Useful to use but please remember it shows you the % your antifreeze is at and not if your antifreeze is good. 20 year old antifreeze can still show a good % but all the anti corrosion additives ect are trashed. ## Features - The models have only one unit system: °F. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze Fluids. - Ethylene Glycol: -84°F-32°F 0-70% VOL - Propylene Glycol: -60°F-32°F 0-63% VOL - AdBlue: urea concentration 30% - 35% - Battery SG: 1.100-1.400sg ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 464 Reviews | ## Images ![TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid - Image 1](https://m.media-amazon.com/images/I/71ma0bCibZL.jpg) ![TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid - Image 2](https://m.media-amazon.com/images/I/71VAhWx8NHL.jpg) ![TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid - Image 3](https://m.media-amazon.com/images/I/51p2OKgbjpL.jpg) ![TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid - Image 4](https://m.media-amazon.com/images/I/41zYQy2nulL.jpg) ![TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid - Image 5](https://m.media-amazon.com/images/I/41KLss8M1wL.jpg) ## Questions & Answers **Q: The measurement scale at left is not labled - is it supposed to be showing g/ml of specific gravity? If so, the top 3 & bottom 3 numbers are wrong.** A: The picture of this scale is not an enlarged view in proportion. This is a schematic. Thank you for your curiosity and seriousness. But you can't use this diagram to measure any battery fluid. **Q: Is it suitable for testing glycol?** A: Yes. It is used to test glycol concentration and freezing point temperature. It is also used for other liquid tests. **Q: Will this come with a box or a bag? Description says bag, but reviews say box...** A: I got a box with is and I believe a bag the refractometer sat in in the box. I gave mine to my old helper and ended up buying one at Fw Webb **Q: How does it know the difference between glycol or DEF or battery water?** A: Not sure. Sometimes you just have to hit the I believe button. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and Easy-to-Use Antifreeze Tester!

I used distilled water to test and it was right on the money. Just a couple of drops on the lens is all you need to test. ## Frequently Bought Together - TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid - Extech PRT200 Non-Contact Phase Sequence Tester - Stant Cooling System Tester, Metallic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/47285665-trz-4-in-1-antifreeze-refractometer-ethylene-glycol-propylene-glycol](https://www.desertcart.jp/products/47285665-trz-4-in-1-antifreeze-refractometer-ethylene-glycol-propylene-glycol) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-09*
