The 4HS+ CiTiceL hydrogen sulfide gas sensor from Week Technology Ltd. operates on a 3-electrode electrochemical principle, offering precise detection in the 0-100 ppm range with a maximum overload capacity of 500 ppm. Its sensitivity is rated at 0.7 ± 0.15 μA/ppm, ensuring accurate measurements for industrial safety and environmental monitoring applications. The sensor achieves a T90 response time of 20 seconds at 20°C, making it suitable for real-time gas detection systems.
This model features a baseline offset of less than ±0.5 ppm equivalent in clean air, with zero shift stability of ±0.4 ppm across a temperature range of -40°C to +50°C. Repeatability is maintained within ±5%, and linearity is consistent across the measurement range, which is critical for applications requiring reliable, long-term performance. Electrochemical sensors like the 4HS+ are standard for H2S detection due to their selectivity and low power requirements.
The 4HS+ CiTiceL sensor is designed for integration into fixed or portable gas detection systems, commonly used in oil and gas, wastewater treatment, and mining industries. Buyers should confirm compatibility with their existing monitoring infrastructure, as the sensor’s 3-electrode design may require specific interface protocols. The absence of a filter in this model simplifies maintenance but may require additional protection in dusty or humid environments.

Before ordering the 4HS+ CiTiceL sensor from Week Technology Ltd., verify its compatibility with your gas detection system’s voltage and communication protocols. Confirm whether the supplier provides calibration certificates and traceability to international standards, as these are essential for regulatory compliance. Request documentation for the sensor’s performance in extreme temperatures or humidity, if applicable to your use case.
Logistics details to confirm include the supplier’s preferred Incoterms, such as EXW or DDP, and whether they provide export-ready packaging for fragile electrochemical sensors. Lead times for specialized gas detection equipment can vary; clarify if the sensor requires pre-ordering or is available from stock. Payment terms should be negotiated upfront, with consideration for secure methods like letters of credit or escrow services.
Quality checks should focus on the sensor’s response time, sensitivity, and baseline stability upon delivery. Test the unit in a controlled environment to confirm it meets the 0-100 ppm range and T90 response time of 20 seconds. Request a calibration report and verify the supplier’s return or replacement policy for defective units. Ensure the sensor’s housing and electrodes are free from damage, as physical defects can impair performance.
