Having outgrown their first factory, DDS move to their current premises in the village of Portchester, Hampshire on the South Coast of the UK. The new facility, located close to the historic Portchester Castle, enables DDS to expand production significantly and has a footprint which allows for future growth.

Relentless R & D

Development of DDS sensor products number 2 & 3 continues with ongoing R&D directed to CO and H2S. Our commitment to investment in automation begins with purchase of first automated sensor filling robot.

A leap forward in CO Safety

DDS launch a new CO sensor which thanks to simplified design, cost-engineered bill of materials and innovative new production techniques proves disruptive from the outset, quickly gaining market share.

H2S completes the set

With the launch of an H2S sensor, DDS begin to offer customers the full O2, CO & H2S suite of sensors commonly required in the industrial safety sector. The DDS triple-pack proves popular, gaining market share around the globe.

Automatic for the people

As global demand for DDS sensors increases, significant investment in automation is made to ensure volumes are met and lead-times are optimised. Automation is a critical thread which runs though DDS to this day - driving quality up, keeping cost down and allowing us to deliver in the high volumes the market demands.

Two's company

DDS launch the GS+4DT - the world's first viable dual CO/H2S sensor. Unlike rival sensors, this new design has extremely low cross sensitivity of H2S gas on the CO electrode, providing users accurate readings which are still best in class today.

A step in the White direction

Sensor industry expert Rob White joins as Global Sales Manager, bringing 15 years experience in the global sensor sector with E2V, City Technology and SGX.

Rob's leadership and expertise expands DDS' global reach and drives sales strategy going forward.

Democratising protection from CO

With CO still one of the largest global killer gases, DDS proudly bring to market their low-cost domestic CO range. The range brings instrument manufacturers unparalleled performance and sensor life at a price point which could only have been dreamt of previously.

Silencing the critics

DDS back up their claims by achieving UL approval on a host of CO sensors for domestic applications. UL certification provided 3rd party validation of the performance, safety and reliability of DDS CO sensors and contributed to the downward cost of achieving CO protection in the home.

Alan Rex joins as Operation Manager

DDS welcome Alan to the fold, bringing with him more than 20 years experience in manufacturing spanning the electronics, automotive and medical sectors, Alan's industry knowledge and management experience bolsters DDS' ability to increase volumes and improve quality over the coming years.

Martin Kelly joins as R&D Manager

Martin's appointment solidifies the position of DDS in the market and commences the formation of the most experienced team of sensor R&D experts in the industry.

A place in the sun

DDS achieve a major milestone with the launch of the GS+7H2S-DC - the DC suffix denoting 'Desert Climate'. This World first, the result of more than 2 years of testing, brings to market an H2S sensor with extreme resistance to High Temperature and Low Humidity.

Originally developed for the Middle East, the DC has since gone on to excel in the US and Asia also.

Lead-Free O2

DDS launch a pioneering new range of lead-free O2 sensors which offer fast, reliable oxygen measurement without the environmental and health risks associated with lead.

Not only do the new lead-free sensors present OEMs with the first viable alternative to lead but provide other upsides including fast response and sensor lifetime 3 x that of their lead-O2 counterparts. This new innovation from DDS
