ROOKS
• Производитель: РУКС
• Catalog no .: ОК-03.0027
The ROOKS refractometer is a precise instrument for testing the electrolyte density and the freezing point of the coolant and the washer fluid.
The refractometer is a measuring device for testing the content of separated fractions in solutions and for testing their physical properties, based on the refraction of light . Спасибо за это, это точно определяет percentage of acid and alcohol (propylene and ethylene) in an aqueous solution.
The refractometer measures:
- electrolyte density, on the basis of which The state of charge of acid batteries is determined,
- freezing point of хладоагенты based on ethylene and propyl glycol,
- The freezing point of the Washer fluid which contains alcohol.
The refractometer examines a drop of solution placed on the расширитель prism, which has different light spectra, depending on the concentration of individual factors.
It has 3 separate scales :
- for battery testing (кг / л), glycol G13 (C),
- этилен G11 / G12 (C),
- washer fluid (° C) .
the product is made of semi-precious materials of the highest durability.
The refractometer must be calibrated with distilled water at 20C.
