High Performance Electrochemical Toxic Gas Sensors

For Industrial Applications


For more challenging Toxic gas detection applications in industry, Nemoto has a full range of cost-effective, high performance Electrochemical sensors. Nemoto Toxic Gas Sensors are widely used worldwide, and have an excellent reputation for accuracy, stability in the field, durability and long lifetimes in service.


Our flagship CO sensor for instruments intended for arduous industrial applications such as steelworks, mining applications, foundries, industrial portable multigas instruments etc. 3-electrode operation ensures the highest levels of linearity, repeatability and longevity.

70 nA/ppm, 0-1000ppm


A lower cost version of the NE4-CO sensor, designed for very cost sensitive applications such as Underground Car Park monitoring systems

50 nA/ppm, 0-1000ppm


Our first foray into the “Series 7” format sensor, Designed for general purpose use in fixed toxic gas Detection heads in industrial safety applications,

100 nA/ppm, 0-1000ppm


We think the best H2S sensor of its type available, with unsurpassed stability and unrivalled speed of response for all industrial safety applications

700nA/ppm, 0-100ppm


Similar to the popular NE4-H2S-100, but with an extended range to 200ppm for process control applications or in areas where high levels of H2S might be regularly encountered.

500nA/ppm, 0-200ppm


Similar to the popular NE4-H2S-100, but with an extended range to 500ppm for process control applications such as Biogas plants.

 200nA/ppm, 0-500ppm


For the reliable monitoring of Formaldehyde in various Industrial, commercial and residential applications.

Output 500nA/ppm, range 0-10ppm, resolves down to 0.02ppm


For the reliable monitoring of NO2  in various applications.

Excellent cost effective sensor, especially in applications such as Underground Car Park Monitoring systems.

 Range 0-30ppm. 600nA/ppm


There are some very good ammonia sensor out there but at very high cost. There also some lower cost but poor performing devices. We claim a sensor which works properly but for a reasonable price. Available in three output/range options, the standard NE-NH3 at  40nA/ppm (0-100ppm), the NE4-NH3-1000 at  8nA/ppm (0-1,000ppm) and the NE4-NH3-5000 at 4nA/ppm (0-5,000ppm).


For industrial safety instruments, emission monitors and portable flue gas analysers

Output 400nA/ppm, range 0-250ppm.


For the reliable monitoring of Chlorine in in Industrial applications including water treatment works, swimming pools, chemical and pharmaceutical plants.

Output 600nA/ppm, range 0-10ppm.
