Refractometers – Handheld – Analog – MASTER-BR

MASTER-BR Handheld Analog Refractometer is a compact, durable, and easy-to-use handheld instrument designed for accurate measurement of glycol concentrations and freezing points. It is widely used in automotive, industrial, HVAC, and laboratory environments where monitoring coolant performance is essential for system efficiency and protection against freezing.
This analog refractometer is specifically calibrated for ethylene glycol and propylene glycol solutions, making it ideal for applications such as engine coolant testing, refrigeration systems, and heat transfer fluid analysis. It allows users to quickly and reliably determine both concentration levels and corresponding freezing temperatures without the need for complex equipment or laboratory conditions.
The measurement range for ethylene glycol (E.G.) is 0 to 70% concentration and 0 to -50°C freezing temperature, while the same range applies for propylene glycol (P.G.), also from 0 to 70% and 0 to -50°C. This makes the MASTER-BR Handheld Analog Refractometer highly versatile for a wide variety of coolant monitoring tasks across different systems and industries.
It features a minimum scale division of 5% for concentration and 5°C for temperature, allowing for straightforward readings that balance ease of use with practical accuracy. Its handheld design ensures portability and convenience, making it suitable for on-site testing, maintenance checks, and routine quality control inspections.
Manufactured by Atago, a globally respected name in refractometry and optical measurement technology, the MASTER-BR model is built with reliability and long-term performance in mind. Its robust construction and simple operation make it a trusted tool for technicians and engineers who require fast and dependable results.
