Antifreeze fluid freezing point Tester user manual

First, the principle:

Antifreeze antifreeze Tester is a measurement of freezing point freezing point of precision optical instruments. The rationale is that the critical angle of total reflection method for measuring the refractive index of the solution, and calibration of the measuring liquid concentration and performance.

Due to its reliable, precision to meet actual needs, small volume, light weight, handsome in appearance, easy to use and so on, are widely used in the automotive industry.

Second, basic parameters:

 

 

&Nbsp; field description:

&Nbsp; the intermediate rod: (ETHYLENE GLYCOL)-ethylene glycol antifreeze fluid freezing point.

&Nbsp;               (PROPYLENE GLYCOL) propylene glycol antifreeze fluid freezing point.

The ruler on the left side: (BATTERY FLUID) battery fluid specific gravity.

&Nbsp;       1.15~1.20 rechargeable

&Nbsp;       1.20~1.25 power

&Nbsp;       1.25~1.30 sufficient power

The ruler on the right side: glass cleaning liquid freezing point

Three, attachment of instructions, screwdriver, straw, cotton flannel.

Four,     Note:

• &Nbsp; not in the relative humidity is greater than the 85% optical system for environment of medium-to long-term placement so as not to be affected
• Liquids and water don't get into the knob and eyepiece to avoid damage to internal components.

 

• Do not drop and collision, so as not to damage the instrument accuracy.

&Nbsp; Note: this type of instrument can measurement of ethylene glycol and propylene glycol, but cannot measure methanol Oh!

 

&Nbsp; This test instrument can measurement:

* Proportion of electrolytes

* Type of measurements of ethylene glycol antifreeze

* Type of propylene glycol antifreeze

* Test the freezing point of water

This instrument is temperature compensated type enclosing the temperature compensation devices

Guaranteed under 10oC~30oC environment temperature accurate measurement
