DHR
DHR – Handheld Digital Refractometer
SCHMIDT + HAENSCH DHR is a compact and practical handheld digital refractometer designed for fast measurement of liquid samples directly in the field. It provides accurate results in less than 2 seconds, with easy operation and automatic temperature compensation.
The DHR is suitable for measuring samples with different viscosities and, thanks to its robust design and IP65 protection, can also be used in demanding environments. Only a very small sample volume is required – as little as 0.1 mL of fruit juice.
