Digital Refractometer for Measuring Ethylene Glycol (0.0~90.0%) ATAGO PAL-91S

Digital Refractometer for Measuring Ethylene Glycol (0.0~90.0%) ATAGO PAL-91S

• Manufacturer: Atago – Japan

• Model: PAL-91S

• Catalog No: 4491

Product Description:

The ATAGO PAL-91S digital refractometer is designed for easy measurement of ethylene glycol in cooling solutions and other related applications. Ethylene Glycol is commonly used in automotive coolants, refrigeration systems, cooling coils, and other cooling equipment. As the concentration of ethylene glycol increases, the freezing point lowers, making it important to adjust the antifreeze solution’s freezing point for specific operational temperatures. This device automatically compensates for temperature fluctuations.
