Featuring a durable, corrosion-resistant build and easy zero calibration, it delivers ASHRAE-standard accuracy in a compact, all-in-one tool. The package includes essential accessories for immediate use and is backed by a 2-year warranty, making it an indispensable device for vehicle maintenance and fluid analysis. ## Description 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.2Year Warranty Free Replacement Guarantee. 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 Review: Je fais du Kombucha et je voulais savoir si il y avait beaucoup de sucre. Après avoir testé avec des boissons zéro sucres et boissons très sucrées, j'ai pu vérifier que ça fonctionne très bien. Et ça vient avec un petit tournevis pour régler la lecture et une pipette pour extraire et déposer le liquide sur la plaque de lecture. Excellent produit. Review: The TRZ 4-in-1 Antifreeze Refractometer is a must-have tool for anyone who wants to accurately test their vehicle's antifreeze. It’s simple to use and provides quick readings for Ethylene Glycol, Propylene Glycol, and freezing point—all in one device. The design is sturdy and the readings are easy to read, so I can confidently know when my car’s antifreeze needs to be replaced. This is a reliable, affordable option for car maintenance. Highly recommend for DIY mechanics! ## 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 | |---------------|-------| | ASIN | B073Q2LSG9 | | Item model number | RHA-100ATC | | Manufacturer | TRZ | | Package Dimensions | 20.6 x 8.4 x 5.4 cm; 320 g | ## 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 ### ⭐⭐⭐⭐⭐ Review *by B***. on 28 December 2023* Je fais du Kombucha et je voulais savoir si il y avait beaucoup de sucre.
