This product is mainly used in car cooling water inspection. You can check the temperature (freezing point) of the condensation of your cooling water. 2. You can also check the freezing point of the windscreen water. 3. Can check the proportion of the battery liquid, instead of using a hydrometer. Safe and reliable. 4, AdBlue: Urea concentration Dimensions: 20 x 7.5 x 5.5 cm. Function 1: Measurement of the freezing point of automotive antifreeze based on ethylene glycol or propylene glycol (G11, G12, G13). Measuring range: -50 to 0 ℃.Function 2: Measurement of the specific weight of battery acid and quickly indicates the charge status of the battery. Measuring range: 1.10 to 1.40 kg/lFunction 3: Measurement of windscreen washer fluid based on ethanol or isopropyl alcohol. Measuring range: -40 to 0 ℃Function 4: Measurement of urea concentration in automotive diesel exhaust fluid (DEF). Measuring range: 30% to 35% Easy to use Easy calibration Zero calibration with the distilled water at 20 °C, automatic temperature compensation between 10 °C and 30 °C (ATC) Quick measurement Place 2, 3 drops of the sample on the main prism, close the plate and look through the viewing window to read the value. Adjustable eyepieces Adjust the eyepiece group optical system: 4-8 times the reinforcement system, continuous manual focus. Can adapt to all eyes. To cover myopia and hyperopia, you do not need to observe the measurement data with glasses. One instrument, many uses, extended mechanical life. An antifreeze refractometer is an important tool for measuring and monitoring the properties of antifreeze to ensure that cooling systems operate properly in motor vehicles and industrial facilities, prolonging their service life. It is an indispensable tool for the repair and maintenance of cooling systems and helps to ensure the quality and performance of antifreeze. Scale easy to read, durable and reliable quality This precision instrument features a high quality optics with extremely even focusing. The entire optical system design precision, five groups of optical lenses with high-quality materials and chrome-plated film processing, light transmission rate of more than 94%. You could use the refractometer in case of low light and read it accurately. Automatic temperature compensation between 10°C and 30°C (ATC) Maintenance Distilled water can be used as a calibration liquid. This product does not need to be calibrated frequently. However, the prism and transparent parts must be kept clean and dry. Accurate measurements are required. Do not place the device in a damp working environment. Do not immerse the device in water. If the device fogs, it means that there is water in the device. You can solve the problem by storing the device in a dry environment for a few days. The device is wear-resistant and corrosion-resistant. It can measure acidic and alkaline as well as other corrosive liquids. However, it is not recommended to measure these liquids for a long period of time. Residues should be cleaned immediately after measurement.

Review: Seems reasonable. - If your a glasses wearer you will have to remove to use the viewfinder successfully, but this is the same for all of these. Seems to be of pretty good quality as much as anything nowadays is. i.e. It's not totally crap masquerading as a tool. The optical clarity seems good and you get a small screwdriver to adjust calibration with water. How accurate? I don't know this, I left my laboratory at home. It does seem to work well enough for the purposes of checking coolant, screen wash, adblue and battery acid. Must be used in daylight for accurate readings and since it's all down to how daylight refracts through the liquid I don't believe the daylight knows whether it's going through a posh refractometer or not. The pastic flap thing is ok but may be the thing that could break on it. But if looked after I don't see any reason for it to not keep working fine. It does not come with a hard case for protection just a pouch inside a cardboard box. You get 4 plastic pipettes also in the box. I have no others to compare with but this does what you would want it to do and the optics part are crisp and clear.
Review: very very good - really good so easy to use my miss can use it and she blond (lolol) really net very simple just look and the very clear blue line tells you the tep how strong the antifreeze is right down to -40 my miss had go and use this has well all in very good very neat comes in nice case 10-10

### ⭐⭐⭐⭐⭐ Basic but does the job
*by U***K on 29 October 2024*

It appears to do what it claims - assess levels of freeze protection in your heating system etc. I don't have any lab results to compare to the readings it gives but I haven't had any frozen radiator problems in my static caravan/cabin when I top up the system and this reads protection down to -13 degrees C and the winter temperatures reached that. There are no batteries, no moving parts and I can see this lasting a very long time indeed if you take care of it.
