Product Name: So2 High Accuracy Gas Sensor Air Quality Monitoring Model NO.: SO2/TC-1 Customized: Customized Certification: RoHS Sensitivity: High IP Rating: IP20 Material: PC Production Process: Integration Output Signal Type: Digital Type Conductivity Type: Volume Control Type Type: Electrochemical Gas Sensor Output: RS485/0.4-2V Detecting Range: Selectable Selectable After Sale Service: Yes Trademark: ASA Transport Package: Paper Box Specification: 46mm*35.6mm*44mm Origin: China HS Code: 8542330000 Product Description 1.Module Outline:The intelligent toxic gas sensor module is with high response speed, good repeatability, and narrow line error. Also, Fuanda Electronics intelligent technology has the world's most advanced solutions. The high-precision & low-temperature drift and multi-point calibration technology ensures the module measurement accuracy and linearity.The Module is designed with the digital output. It's unnecessary to re-calibrate if the user makes the module for binary development or direct use, which will reduce the development and application time cycle. There are two application interfaces: Diffusion, pump-priming.2.Main Feature:1)Can accurately detect low or high concentration gases;2)Adopted the best international amplifier and 24-bit ADC, with high precision, good resolution;3)Adopted the best international power processing devices to protect the module measurement accuracy and strong anti-interference;4)Used the multi-point calibration technology to protect the linearity on the high range;5)Adopted to the high-precision low-temperature drift of the device6)Two install types: Diffusion, pump-priming;7)Small size, can be adapted to customer direct application or the second development;3.Technical Parameter:Detecting GasSO2Detecting PrincipleElectrochemical(Without bias voltage:NO,ETO,H2O2)Detecting Range500 ppbSensor response time1 ppbResponse time<20 secondsPrecision≤±3%FS(Actual concentration, higher accuracy depending on the specific sensor)Repeatability≤±2%Line Error≤±2%Zero Drift≤±2%(F.S/year)Power Supply3.3-5.5 VDCOperating Current20mA~30mASensor work Temperature-20ºC-50ºCSensor work Humidity0-90%RH(no condensation)Sensor life>2 yearOutput SignalRS485 / 0.4-2VInstallTypePump-housing or Thread-housingTracheal tubeDiameterThe inner diameter of the trachea is 4MMRecommended gas velocity300-600mL/min4.
