Real time spray droplet temperature measurement

A unique technology in the world

2 ranges of measuring devices

Created in 2017 by two researchers worldwide recognized as experts in the optical characterization of multiphasic media, RainbowVision offers devices for real-time measurement of temperature and size distribution of spray droplets.

Compact, portable, insensitive to vibrations, preset in laboratory, associated with a very intuitive software and processing code, these devices, very easy to use, measure the drop temperature in real time with great precision, in a wide range of temperature and pressure. The concept of measurement technique used is based on the analysis of the light scattered around the rainbow angle : GRT (Global Rainbow Technique).

This unique technology increases economic efficiency while reducing the ecological footprint of the spray industry.

Our products

GRT-XL

Dedicated to laboratory research, the GRT-XL works at room temperature, in a range of refraction index between 1.30 and 1.50, for drops between 10 and 300 µm within a working distance of 15 and 20 cm.

GRT-mini

Dedicated to in situ insertion in hostile environments, the GRT-mini is optimized for a single product (e.g. water), for drop sizes between 10 and 300 µm, within a working distance of 7 to 10 cm. Originally designed to work in freezing rain conditions (speed of flow between 7 km/h and 900 km/h, temperature of -40°C, ..), it can be adapted for other hostile environments.
