DEKRA Process Safety


Electrostatic Instrumentation is the most respected name worldwide for specialist instrumentation in the field of electrostatics. A list of our instruments can be found in the right hand index.

About Electrostatic Instrumentation

Established by renowned electrostatics research expert Dr John Chubb 30 years ago, JCI was acquired by DEKRA in 2009 and has become the market leader in the design, manufacture and supply of state-of-the-art electrostatic instruments, accessories and safety services.

Electrostatic Instrumentation has tens of thousands of hours experience in providing electrostatic solutions for our clients. We produce customised test equipment to solve electrostatic problems, undertake hazard assessments and electrostatic audits, and most recently introduced market leading JCI 140 field-mill technology to our new JCI 180 Lightning Warning System which was launched at Electrostatics 2013 in Budapest. Should the unthinkable happen, we are also here to provide a rapid response to incident investigation and, if necessary, expert witness services. Electrostatic Instrumentation also provides GLP compliant electrostatic testing and calibration services, safety consultancy and open-access and in-company training courses.

Electrostatic Instrumentation Range

Below, we have listed our entire Electrostatic Instrumentation range based on equipment class, making it easier than ever for you to identify the correct solution for your needs. If you cannot find precisely what you require, please take a look at our Custom Manufacture page, as we will more than likely be able to assist with a bespoke product tailored to your specific needs.
