- Exceptional Long-Term Stability & Durability:
- Long-term zero-point stability ensures accuracy over time.
- Fast response time provides real-time detection of gas concentration changes.
- Superior linearity guarantees precise measurements.
- Anti-poisoning design enhances sensor lifespan.
- Leak-Free Electrolyte Design – Unlike traditional electrochemical sensors, the DS4 features a solid electrolyte, eliminating the risk of liquid leakage due to high humidity or material aging.
- No Warm-Up Required – immediate gas detection upon power-up
- Easy Service & Self-Recognition – Plug-and-play and hot-swappable design. Outputs identity information such as gas type and detection range, providing flexible usage. Precise factory pre-calibrated, supports secondary development calibration & factory reset.
How It Works
The DS4 operates at a fixed potential, where the target gas diffuses through a controlled barrier into the sensor cell, triggering an electrochemical reaction at the working electrode. Simultaneous oxidation and reduction reactions generate a current that is directly proportional to the gas concentration. A reference electrode, maintained by a potentiostat, ensures consistent operation, making the DS4 an accurate and stable gas sensing solution.
