Anti-freeze Refractometer PCE-DRA 1 seconds and precise measurement results / Waterproof ABS housing IP 65 / large LCD display / with automatic shut-off / for ethylene glycol and propylene glycol Information about the anti-freeze Refractometer of this anti-freeze Refractometer PCE-DRA 1 is used for the quick determination of the anti-freeze content in aqueous solutions. With this digital coolant refractometer PCE-DRA 1, you can quickly and accurately determine the content of antifreeze in your plants and machines. This handy refractometer PCE-DRA 1 is used both in industry and in the automotive sector. Simply put a few drops of the liquid into the stainless steel sample well with the glass prism, close the lid, start the measurement and read the result on the display ABIN of the operating instructions for the vehicle or the system you will find information on the mixing ratio of the antifreeze. This should not only be observed in winter, but throughout the year, as additives for corrosion protection and maintenance of the coolant circuit are also included with the anti-freeze. Garages for motor vehicles often check the mixing ratio above the freezing point of the cooling water. For many areas, a coolant freezing temperature of – 27°C is recommended. Even in frost-free areas, the addition of "antifreeze" is necessary, as these not only reduce the freezing point of the cooling water, but also increase the boiling point. If you have measured values that are outside the recommended range, you can remove some cooling water and add either antifreeze or water as required. Then perform a new measurement using the Refractometer antifreeze. The PCE-DRA 1 digital refractometer can determine either the concentration or the freezing point of the mixture per measurement. If you want to check both, you make two measurements. Before starting the measurement, select the desired characteristic curve in the device menu: > S01 - Concentration of ethylene glycol in the coolant in volume percent, > S02 - Freezing point of the coolant with ethylene glycol, > S03 - Concentration of propylene glycol in the coolant in volume percent, > S04 - Freezing point of the coolant with propylene glycol. A distinction must be made between ethylene glycol-based freezers and propylene glycol-based freezers for the measurement. In motor vehicles, ethylene glycol (also monoethylene glycol, ethylene glycol, ethanol diol) is used predominantly. With this glycol, the freezing point of the cooling water decreases to about -10 °C to -40 °C at a proportion of 20 to 50 percent, depending on the manufacturer At higher levels of ethylene glycol, the freezing point rises again and is approximately -13 °Celsius when used undiluted. Propylene glycol (also monopropylene glycol, propandiol) is less toxic and is degraded faster. This is why it is used for cooling and heating systems in the food and pharmaceutical industries as well as for solar systems and heat pumps. The freezing point decreases with propylene glycol with increasing concentration to approx. -59 °C with undiluted application. If necessary, dose slightly if it is not sufficient and then perform a new test with the measuring instrument. The manufacturer has designed the refractometer anti-freeze to protect the glass prism from damage. The simple operation guarantees a user-friendly handling and almost excludes an operating error of the car refractometer. In order to conserve the battery of the meter, the manufacturer has equipped the antifreeze refractometer with an automatic shut-off function. When not in use, the refractometer switches off automatically after one minute. If required, the user can calibrate the car refractometer himself at any time, in which he gives a few drops of distiled water into the measuring recess and triggers the calibration by pressing a button. Application areas The task of a reputable manufacturer is to offer good quality and safety. The user wants a reliable product with a long service life. What was both wanting is to avoid errors and failures. The use of auxiliary equipment - such as a coolant refractometer in this case - reduces the risk of equipment failure and significantly reduces the quality during the manufacturing process. Modern high-performance equipment often causes the substances and liquids to heat up and the use of low-quality coolants and antifreeze can lead to failures and rapid wear. A portable coolant refractometer is an instrument that allows the operator and operator to strictly control the condition of the fluids used to support engine operation. Concentrations that are too low or too high can mean the end of the vehicle's running time for the engine and other parts of the vehicle. The system can become clogged by dirt, surfaces can overheat, various types of corrosion, leaks and many other problems are possible - this is the result of using antifreeze or coolant with unnecessary additives and bubbles. In daily life, the coolant refractometer is a reliable monitor that contributes to a long life of the vehicle with few problems.
