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 liquid, 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.< br> 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.
