New miniature electrochemical gas sensors for industrial safety

Mar 25 2021 Read 211 Times

DD-Scientific recently unveiled a new range of high-performance products designed for industrial safety applications. The DceL suite of products deliver industry leading robustness and performance for the measurement of toxic gases and oxygen but are provided in an ultra-compact package which can enable detector size reduction.

The newly launched products were inspired by numerous discussions with DD-Scientific customers who have become accustomed to the high quality of their products but were seeking further miniaturisation. According to Martin Kelly, R&D Manager, “Our customers are committed to providing greater ergonomics and increased functionality in new instrument developments. The DceL has been developed to meet their needs; the smaller size of the sensors allows much greater flexibility to provide smaller gas detectors or provide additional space for longer battery life or other features.”

Traditionally, reducing the size of electrochemical sensors results in a compromise on performance or longevity, but the DceL has been designed to overcome these limitations. The internal volume of the sensors accommodates the same ratio of electrolyte found in larger DD-Scientific sensors and the use of existing electrode technology ensures the same responsiveness to gas and low drift performance throughout their working life. The sensors have been subjected to extreme environmental conditions over long periods of time with no reduction in speed of response or linearity.

The DceL range includes sensors for the most commonly measured toxic species such as carbon monoxide, hydrogen sulfide, nitrogen dioxide, sulfur dioxide and ammonia. It also includes two options for oxygen sensing; a traditional two year lead based oxygen sensor which generates its own current or a novel lead-free version which can provide working lifetimes greater than five years. The range also includes DualTox technology with one sensor capable of measuring carbon monoxide and hydrogen sulfide simultaneously.

The sensors are manufactured in high volume on DD-Scientific’s automated production lines with many of the processes carried out using robotic equipment. All sensors are fully tested with their target gas prior to despatch with sophisticated quality controls in place to ensure customers receive their products in perfect working order.

All of the products are backed by the world leading technical support for which DD-Scientific has become highly reputed with assistance available at all stages of evaluation. If our customers or partners need integration, application or electronic circuitry advice, DD-Scientific’s highly experienced team of scientists and engineers are on hand to provide timely and accurate help.

The DceL’s launch is further evidence of DD-Scientific’s commitment to continued innovation driving our customers competitiveness. To learn more about the DceL range of sensors or any of our wide range of high performance products, please visit.
