Hydramotion are still in production, and have put in measures to adhere to all Government health and safety guidelines of home working and social distancing.

Many of our Viscometers are used in industries considered ‘essential’ by the UK Government, such as food, healthcare and pharmaceutical so we’re receiving orders as normal and processing them as efficiently as possible. We are absolutely committed to playing our part in the Coronavirus battle.

We continue to work closely with our supply chain to minimize disruption and maintain acceptable lead times; however, shipping and delivery times remain a challenge and are typically being extended. To this end, we continue to encourage our customers to place orders as soon as possible to ensure we can meet your lead time requirements.


Our mission is to take viscosity measurement from the lab to the places it’s needed most – on the line, in the field, at the site. And where the lab is still a feature, to radically alter the way fluids are tested and transform the throughput speed.

This manifesto is the basis of our range of products. A viscometer for every application, in any fluid and any location. Easy to set up and simple to use. Viscosity for everyone.

Viscolite - the truly portable viscometer

Discover the viscolite - our portable viscometer

The Truly Portable Viscometer

A genuinely light and portable instrument, with the trademark Hydramotion accuracy and reliability. The Viscolite works in any volume of fluid – just dip and read. It’s also incredibly robust so you can even stir the fluid with it whilst taking a viscosity reading!

With its long battery life and carrying case it is the perfect solution to viscosity measurement on the move, either in the field, the factory or lab.
