Whistobrook has been at the forefront of developing micro instrumentation for the past 20 years. We have concentrated on designing instruments to measure and log electrochemical sensors. These have included potentiometric, voltametric and conductivity sensors as well as temperature and location. Our first units, supplied in 2000, were designed as remote instruments to measure pH and send data via RF to a base station. Since then, we have designed units to be included in consumer products, as wearable instruments and as single use POC diagnostics. Recently we collaborated to design one of the world's smallest potentiostat with a LCD display and Bluetooth communication. Early units were around 30mm X 30 mm but with the latest chip and package technology, units are now as small as 10mm X 10mm.
Two channel potentiostat with wireless communications
Amulet handheld potentiostat
Whistonbrook was contracted to develop the potentiostat component of the Amulet portable potentiostat. The Amulet can be configured to carry out most electrochemical measurements. It includes a rechargeable battery, a lcd display and a Bluetooth transmission module to connect to mobile phones. A large memory capacity allows for measurements to be stored and downloaded at a later time. A variety of current ranges can be factory configured.
This potentiostat with wireless communications is the smallest micro potentiostat that we have developed so far. It measures just 10mm X 10mm and was developed with the University of Kent as part of a large Instrumentation contract to develop micro diagnostic tests.

Remote pH logger
These tiny potentiosats were developed to allow our clients to test various designs and methods in the laboratory before committing the final design to the prototype. The micro boards have connection for various sensors and a USB communication link to display and download test data to a laptop. Measurement current resolutions and ranges can be changed to cover most cases. Once the tests confirmed the circuit yields the best results, the design is transferred to the final prototype.
This tiny logger was developed for a client who only wanted to record data from an electrochemical sensor when the unit was moved. Data was then sent via RF to a base station allowing the logger to be completely sealed in a consumer product.
This logging instrument was designed to fit in the top of an aerosol can. When the can was used the logger was switched on and data recorded and stored in memory. After a few months the can was recovered and the data downloaded by a wired link.
This remote logger was one on the first fabricated by us in 2000 and was used to remotely measure pH and temperature in streams and lakes, sending data back to a data hub 100 metres away.
