The SMD1003E sensor is a high-performance, low-cost primary battery type electrochemical sensor that using advanced electrochemical sensor preparation technology. It can be adapted to high temperatures (70°C), low temperatures (-40°C ). The SMD1003E sensor complies with the various performance requirements of electrochemical carbon monoxide sensors in the US UL2034 and EU EN50291 standards.
SMD1003E has been miniaturized in design, making the sensor small in size and can be directly welded on the PCB, ensuring product life while greatly reducing product costs. This product is recommended to have a service life of 6 years and a one-year warranty. If there are any quality problems within one year, it will be returned or replaced for free.
It can be widely used in carbon monoxide gas detection and fire detection in civilian households in high and low humidity environments.
