The CM-ISα-EG is an in-line refractometer specialized for ethylene glycol (EG)-based refrigeration and antifreeze systems, based on Atago's CM-800α platform. The system simultaneously measures EG concentration (0.0–90.0% range, ±0.4 accuracy), freezing point (-50°C to 0°C), and refractive index (1.32000–1.49100).

With ATEX/IECEx certification, the instrument can be safely deployed in explosive atmospheres (e.g., aviation de-icing, industrial refrigeration facilities). RS-232C or 4–20 mA output enables seamless integration with existing SCADA and automation systems.

Designed for facilities requiring continuous EG concentration monitoring in HVAC systems, chiller plants, process cooling, and industrial heat exchangers. The device lacks IP65 protection rating and automatic temperature compensation; additional safeguards are recommended in applications requiring these features.
