Optical instrument for checking the freezing point of the coolant and washer fluid as well as the state of charge of the battery. Shows the freezing point of both ethylene glycol,
propylene glycol and washer fluid with three different scales showing in °C, as well as a scale for the specific gravity of the acid. The antifreeze and the specific weight of the acid are marked with
sharp light/dark line on the scale. The control of the specific gravity or the freezing point takes only a few moments regardless of the temperature of the liquid, only
a few drops are needed to do the test. The MT-414 comes with a custom box and suction pipette.
