With a temperature range from -84°F to 32°F and precise concentration readings, it’s perfect for vehicle maintenance, HVAC systems, and battery care. Durable and easy to use, it ensures your fluids are always optimized for peak performance. ## Description Product description • Battery electrolyte condition. • Freezing point of ethylene glycol-based antifreezes and coolants. • Freezing point of propylene glycol-based antifreezes and coolants, heating systems, solar thermal collector circuits, heat pumps. • Diesel exhaust fluids. The models have only one unit system: ℉. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. You can use it to check the temperature (freezing point ) of the condensation of your cooling water. This product has been improved to a higher level of accuracy. The measured data is close to the ASHRAE standard. The new product adds functionality and can be used to measure AdBlue. The unit can be used to check the proportion of battery fluid, instead of the use of hydrometer. Safe and reliable. This product is used to measure the freezing temperature limit of automotive coolant. It is used as a tool to protect the car engine. The instrument is resistant to abrasion and corrosion resistance. Can be measured acidic and alkaline and other general corrosive liquid. Compensation temperature range: 50℉- 86℉ Calibration: Zero calibration with water close to 68 ℉. Warning-Maintenance: 1.Calibration liquids can use clean water. This product does not require frequent calibration. The temperature of the liquid to be measured should be close to the temperature of the prism to measure the data is accurate. 2 The instrument is resistant to abrasion and corrosion resistance.Can be measured acidic and alkaline and other general corrosive liquid. But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. 3 This is an optical instrument. Do not need regular maintenance. But you have to be careful, the vast majority of damage is due to fall, which will cause the instrument difficult to repair. Package included: 1 x Refractometer 4 x Plastic Pipette 1 x Mini Screw Driver 1 x User Manual 1 x Cleaning Cloth 1 x Storage Bag and carton Using this refractometer will keep your car up to date and prepare your vehicle for the Winter. Testing antifreeze Homemade antifreeze - based on freezing point Homemade antifreeze -based on concentration percentage Detecting battery fluid Detecting ADblue fluid Homemade adblue Review: Very simple to use. - Works great. 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. Review: Great refractometer at a 1/4 of the cost. - At first I was looking for a refractometer just to test the quality of DEF fluid before I put it into my truck and to troubleshoot any poor quality DEF messages. I didn't know they made 4 in 1 testers until I started searching on desertcart. After reading the reviews on several refractometers I decide to purchase this 4-in-1 tester. I like the fact that it reads in fahrenheit and not celsius. It automatically compensates for temperature between 50 and 86 deg F. and tests 4 different types of fluid. Ethylene glycol based antifreeze ( DEX Cool ) , Propylene based antifreeze, Battery fluid and Def Fluid. It also has an adjustable eye piece to adjust the focus when looking thru the unit. It comes with a pull string storage pouch, 4 plastic eye dropper tubes to sample fluids, a lens cleaning cloth, instruction pamphlet and a tiny screw driver to adjust the calibration. It is a compact unit, approx 6" long. Calibration is checked by using distilled water. I checked the calibration of my unit out of the box and the calibration was dead on. For the price this is a great tester. I recommend it. ## 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 456 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 ### ⭐⭐⭐⭐⭐ Very simple to use. *by C***R on April 15, 2026* Works great.
