WHO WE ARE – Janetsons Oy

Janetsons Oy brings together more than 45 years of experience in process refractometer innovation, design, and application know-how. At the heart of the company is Jan Kåhre, one of the true pioneers in the field and the mastermind behind several of the process refractometers that are widely used on the market today.

With the new ThinProbe, Janetsons is taking refractometer technology to the next level. This latest innovation is a technological breakthrough that opens process refractometry to an entirely new market segment through its compact 1/2-inch probe connection. By enabling installation in applications and process connections that have previously been difficult or impossible to address with traditional process refractometers, ThinProbe sets a new benchmark for compact, high-performance measurement.

All Janetsons instruments are manufactured in Finland in accordance with ISO 9001 quality standards, reflecting the company's commitment to precision, reliability, and consistent product quality.

Officially launched at INTERPHEX 2026 in New York, the new ThinProbe is already setting a new standard in process refractometry and demonstrating Janetsons' role as a true innovator in the industry.
