About JCI Chilworth - a DEKRA Company,

The Global Experts in Electrostatic Process Safety

Established by renowned electrostatics research expert Dr John Chubb 30 years ago, JCI was acquired by Chilworth Technology 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.

JCI Chilworth 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 being 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. JCI Chilworth also provides GLP compliant electrostatic testing and calibration services, safety consultancy and open-access and in-company training courses.

As part of Chilworth-a DEKRA Company, JCI's client base now covers over 40 countries and includes manufacturing companies in the fine chemicals/pharmaceutical, bulk organics, food stuffs,paints, resins/plastics, dyestuffs, pigments, agrochemicals, soaps / detergents, oil/petrochemicals and the legal and insurance fields to name a few.dickie.jpg

With increasing emphasis within industry on safer plant and processing, the role of Chilworth as a centre for process safety expertise has never been more important.

Join great companies such as Glaxosmithkline, Unilever, BASF, Pfizer, Tate & Lyle, Nestle, BP and others in making Chilworth part of your safety team. Visit our dedicated stand at Electrostatics 2013 to see why JCI Chilworth are acknowledged by our peers as The Experts in Electrostatic Process Safety.  


New JCI 180 Lightning Warning System 

Dekra 0912 056.jpg

JCI Chilworth are delighted to announce the launch of our new JCI 180 Lightning Warning System.

The JCI 180 Lightning Warning System is an advanced, portable and cost effective solution using latest detection algorithms to forewarn of lightning build-up, even before strikes are seen or thunder heard. It detects storms remotely providing the warning needed to better safeguard people and installations.

 "We are very excited about the JCI 180 and the world class performance it brings to lightning detection" says Dr. David Firth at JCI Chilworth. "Leading organisations know that to achieve better people and infrastructure safety they need the very best in mobile, lightning warning detection." adds David.

Full details of this new system can be accessed via the main JCI index to your left.


Other Leading Electrostatic Instruments in the JCI Range

Other instruments are particularly important within the wider JCI product range include: 

JCI 140 Handheld Static Monitor

JCI 140 The JCI 140 handheld Static Monitor is an exceptionally high quality and high specification instrument. It is easy for anyone to use, and will show where static electricity is present, giving both polarity and magnitude. As such it is a key instrument in diagnosing the source of static problems and hence a first line of attack in systematically assessing such problems and then proposing solutions.

Although it is easy for anyone to use, the specification of the JCI 140 means it is also a very serious instrument for industrial and academic professionals in the field of electrostatics.

An analogue output and mains power supply make it suitable for extended monitoring where required, and a number of optional accessories extend its applications to such items as very high input impedance, high voltage voltmeter and a charge-measuring Faraday Pail. A high speed option increases the normal frequency response of -3 dB at 120 Hz to -3dB at 400Hz.

JCI 155v6 Electrostatic Charge Decay Analyser 

JCI 155v6The JCI 155 provides a unique all-in-one package capable of measuring the charge decay time for materials. This is a key and intuitive indicator of the susceptibility of materials to electrostatic problems and possible electrostatic hazards. It is also useful for Quality Assurance resting where materials are intended to address or control possible electrostatic problems and hazards. The unit can be placed directly on the surface to be tested, but optional bases and inserts ensures a range of material types including sheet, film, textiles, powders and liquids can all be placed in the optimum location for testing. If the active JCI 176 Charge Measuring Base is used,the JCI 155 will also measure capacitance loading.


JCI 131 Adverse Conditions Field Meter

JCI 131The JCI 131 Field Meter is a high specification fieldmeter, yet is designed for extended use in adverse conditions, including outdoors. It has been extensively used for monitoring around high voltage power lines, but is clearly very suitable for many other applications.

One such application is in the JCI 504 Lightning Detector. This gives advance warning of likely lighting activity by a combination of electric field measurements and radio detection of lightning activity. The radio detector allows lightning to be detected from some distance away, and the field measurement means that storm systems likely to give rise to lightning can be identified even before the first strike! Hence, it is effective even near to extensive plane areas such as seas and oceans, providing advance warning for lightning activity anywhere where electrical storms could potentially disrupt an activity or where lightning might represent a specific and avoidable hazard such as for golf courses, inland and shoreline watersports and track and field events.

A fast version of the JCI 131 is also available which is able to measure electric field at mains frequencies. An optional accessory base unit will even resolve alternating and near-DC fields, which is one of the reasons it is so suitable for use in the region of power lines.

All the JCI instruments referred to above have a range of optional accessories enhancing and extending functionality, which together with JCI's other electrostatic instrumentation makes for one of the most comprehensive ranges of exceptional quality instruments of their type in the world. Further information about the full range of JCI instruments can be found using the product index to the left.
