Power supply: Built-in 3.7V rechargeable lithium battery
Dimension: 147x46x27mm
Weight: 115g (Including battery)
Features:
Quickly measure the concentration of coolant
Automatic temperature compensation
Brix and refractive index can be displayed
Refer to the refraction coefficient of coolant, for example: the refraction coefficient of grinding emulsion is 2.1, the reading value is 6%, so the actual concentration is (2.1x6%)=12.6%
