About Us
We have been developing and marketing laboratory dissolved oxygen instrumentation since 1981 and are recognised as one of the leaders in this field. You will see our instruments in use in major laboratories throughout the world.
All our instruments are based upon microcathode oxygen electrodes, which were originally developed for use in the demanding conditions of clinical blood gas analysis, and which can be used, when required, without stirring of the medium.
The electrodes are used with accessories, which have been designed for specific laboratory applications.
Respirometry Research
We are one of the world's leading suppliers of precision respirometry and dissolved oxygen instruments for biomedical and aquatic respirometry.
Wastewater Treatment
We specialise in wastewater treatment instrumentation for activated sludge plants. With decades of experience with dissolved oxygen measurement, we offer a range of products and services for wastewater toxicity testing.
