SPEC Sensors’ Screen Printed ElectroChemical sensor technology (SPEC Sensor™) revolutionizes the
current state of the art, enabling new applications in consumer and industrial safety monitoring. SPEC’s
printed sensors offer the performance of the best quality electrochemical sensors at a fraction of the
price. SPEC’s printed sensors are also ultra-thin and tiny, offering easy integration into wireless, portable,
and networked solutions. These sensors are ideal for health, environmental, industrial and residential
monitoring, because of their high performance, low cost and small size.

Temperature fluctuations have a predictable, easily compensated effect on the sensor signal. The figures
at below shows the typical Temperature dependency of 3SP_CO_1000 sensors under constant humidity
of 40-50 % RH. This is a very uniform and repeatable effect, easily compensated for electronically with
the appropriate thermistor, or in firmware.
NOTE: Ozone Sensors will have different but easily compensated variances.

Asia Pacific Chemical Sensors Market

Asia Pacific Chemical Sensors Market Chemical sensor is a device that converts chemical information into electric signals, whose magnitude is related to the concentration of the analyte. The information is deduced from chemical reaction of the analyte or from the physical properties of the system under consideration. It consists of a receptor and transducer, that operate in real time and are controlled by kinetic and thermodynamics of a chemical reaction. The increase in global energy usage and undesirable release of pollutants into environment has led to increasing use of chemical sensors which is driving the chemical sensors market. These sensors are extensively utilized for environmental conservation activities, thus ensuring better environmental conditions. Chemical sensors are considered as advanced tools which are used for identifying and quantifying analytes for various chemical industrial processes. These are extensively used in research laboratories, chemical and process industries, defence sector and other critical applications.
