Handheld Battery & Antifreeze Refractometer, ATC

The portable refractometer for antifreeze and batteries is an optical instrument designed for the rapid and accurate determination of the freezing point in glycol solutions and the density in battery electrolytes. Its Automatic Temperature Compensation (ATC) system allows for reliable results even under variable thermal conditions, ensuring consistency in measurements. This equipment incorporates several reading scales that allow the evaluation of different parameters in a single device. It allows the determination of battery charge density in a range of 1.15 to 1.30 kg/l (specific gravity), as well as the freezing point in ethylene glycol and propylene glycol solutions within an interval of -50 °C to 0 °C. The reading is done directly through the eyepiece, with clear and quick interpretation. Its compact and ergonomic design facilitates its use both in the laboratory and in field applications, without the need for specialized training. The metallic structure provides mechanical resistance and durability, ensuring stable performance even in demanding environments. The procedure for use is simple: a few drops of the sample are placed on the prism, the cover is closed, and the result is observed by orienting the instrument towards a light source. Calibration is carried out using distilled water, allowing the equipment's accuracy to be maintained quickly. The equipment is supplied with accessories that facilitate its use and maintenance, including sampling pipettes, a protective case, a transport pouch, an adjustment screwdriver, and rubber eye protectors. Its approximate dimensions are 30 × 40 × 200 mm, which allows for comfortable and safe transport. This refractometer is an essential tool for the maintenance of refrigeration and energy storage systems, as well as for applications in automotive, industry, and technical control, where the quality and properties of fluids need to be verified quickly and reliably.
