Product Description:
YJJ CL2-A1 Chlorine Gas Electrochemical Sensor 0 - 20ppm for Portable Chlorine Gas Detector
Features:
I. Core Parameters (Electrochemical Cl₂ Sensor)
Detected Gas: Chlorine Gas Cl₂
Measurement Range: 0 - 20 ppm (ensuring accuracy range)
Short-term Overload: Maximum tolerance 50 ppm
Sensitivity: -350 ~ -750 nA/ppm (under 10 ppm chlorine gas conditions)
Response Time T90: < 60 s (typical value < 40 s)
Resolution: < 0.02 ppm (able to detect ppb-level minor leaks)
Zero Point Current: ±0.4 ppm equivalent value
Linear Range: 0 - 5 ppm with good linearity, full range error ±1.5 ppm
Environmental Conditions
Temperature: -20℃ ～ +50℃
Humidity: 15% - 90% RH (no condensation)
Air Pressure: 80 - 120 kPa
Service Life: ≥ 24 months (original factory 24-month warranty)
Long-term Drift: Zero-point drift < 0.05 ppm/year; Sensitivity annual drift < 10%
Physical Dimensions: Φ20.2 × 16.5 mm, Weight < 6g, Standard 4-pin A-series package
Cross-Interference: SO₂ interference is small, CO, H₂, ethylene, etc. interference are extremely low, suitable for complex working conditions
II. Product Principle
Fuel cell type electrochemical sensor, chlorine gas undergoes redox reaction on the electrode surface, outputting a weak current signal, the current size is proportional to the chlorine gas concentration, the rear-end circuit converts the current into concentration values.
III. Main Applications
1) Instrument Integration (OEM preferred)
Portable chlorine gas detector, single toxic gas alarm instrument
Fixed online chlorine gas transmitter, gas monitoring probe
Industrial online monitoring module, PLC gas collection module
2) Industry Application Scenarios
