FirstCheck 6000 is launched for the first response market in the US. It’s the first PID instrument to combine complete multi-gas detection from ppb levels up to 10,000ppm combined with traditional multi-gas sensors for oxygen (O2), hydrogen sulphide (H2S), carbon monoxide (CO) and explosive gas (LEL) detection.

In addition, Hydrosteel 7000 is launched; this product is a fixed, totally non-intrusive device for the continuous monitoring of hydrogen flux corrosion at high criticality sites within petrochemical, gas production and petrochemical refining operations.


ION Science launches the PhoCheck 1000, a simple VOC detector for entry into the PID market.

A Smart Award is received for the development of a permanent Hydrosteel monitoring system after the success of the portable device.

PhoCheck 2000, 3000 and 5000 re-launched with a graphical format.

ISO 9001:2000 certification is achieved.


Dr. Frank Dean joins the Board of Directors after six valuable years of service as a Research Manager. Together with Mark Stockdale and Duncan Johns, they purchase the controlling interest in the company.

ION Science America’s is formed with Mr. Geoff Hewitt as CEO, a former VP of Sales and Marketing for HNU. HNU was the very first PID Company founded in the early 1970’s.

A worldwide patent on PID Fence Electrode was applied for–giving low-level stability in volatile organic compound (VOC) and relative humidity (RH) atmospheres.


The PhoCheck range of VOC detectors is extended with two new models; the 2000 and 3000 Ex. In addition, a new calibration device called the CalCheck is launched for easy calibration of gas leak detectors.

ION Science develops a new high-temperature collector that wins the company a Smart Award to explore the potential of a development for detecting corrosion under insulation.


ION Science launches the PhoCheck 5000 Ex, the company’s first PID instrument that detects volatile organic compounds (VOCs) down to parts-per-billion (ppb) levels.  Also launched this year is the Hydrosteel corrosion monitor, the world’s first truly portable hydrogen permeation in steel analyzer for the Oil and Gas industry.


Duncan Johns joins the company as Managing Director taking over from Mel Vinton. With a wealth of international sales and management experience within the gas detection industry, Duncan joins to strengthen the management team and increase sales internationally.
