Information on the refractometer for antifreeze
The PCE-DRA 1 refractometer for anti-freeze agents is used to determine the anti-freeze content of aqueous solutions immediately. With this digital refractometer for anti-freeze agents you can quickly and accurately know the proportion of anti-freeze agents in
Just insert a few drops into the cavity of stainless steel samples with glass prism, close the lid, start measuring and read the value on the screen. You will find information about the proportion of the mixture in the vehicle or installation manual. This value should be mainta
The PCE-DRA 1 digital refractometer determines the concentration or freezing point of the mixture when measuring. If you want to obtain both values, you will need to make two measurements.
> S01 - Concentration of ethylene glycol in % vol. in the refrigerant,
> S02 - Freezing point of the refrigerant with ethylene glycol,
> S03 - Concentration of propylene glycol in % vol. in the refrigerant,
> S04 - Freezing point of the refrigerant with propylene glycol.
When making measurements, a distinction must be made between ethylene glycol and propylene glycol-based anti-freezing agents. Ethylene glycol (also known as ethylene glycol or ethanodiol) is mainly used in motor vehicles. This glycol reduces the
The manufacturer has designed the refractometer for anti-freeze so that the glass prism is protected from damage. The three keys of the refractometer ensure easy handling and virtually exclude any malfunction. In order to increase the battery life, the manufacturer has equipped the
Scope of application
The duty of a serious manufacturer is to offer good quality and safety. The user expects to receive a reliable product with a long service life. What both want is to avoid failures and breakdowns. The use of auxiliary tools, such as in this case an anti-freeze ref
