Produkt-Neuheit

At Sensor+Test 2025, we are excited to introduce the DS4 Digital Gas Sensor, a groundbreaking advancement in gas detection technology. Designed to meet the needs of modern industrial applications, the DS4 leverages printed solid polymer electrochemical sensing technology to deliver precise, reliable, and intelligent gas sensing capabilities.
Key Features & Advantages
The DS4 Digital Gas Sensor is engineered with cutting-edge features in a standard sized housing to ensure high performance and seamless integration into various systems:
• Advanced Sensing Technology: Utilizes solid polymer electrochemical sensing with a three-electrode arrangement (working, counter, and reference electrodes) for continuous and stable gas concentration measurement.
• Smart Integration & Connectivity: Equipped with a powerful microprocessor, high-precision ADC, and intelligent algorithm, ensuring optimal data acquisition and processing.
• Comprehensive Testing & Calibration Solutions:
o Single Digital Gas Sensor Evaluation Kit: Facilitates individual sensor testing with UART to USB data transmission.
o Bulk Evaluation Kit: Supports batch testing and calibration of over 25 sensors via RS485 to USB transmission, allowing large-scale sensor evaluation.
o 4S Flow Cap: Enables compatibility testing and calibration for individual or multiple sensors through diffusion testing.
• Low Power Consumption, Sleep Mode & Wide Power Supply Range: Operates efficiently within a 3.3V to 12V DC range (recommended 5V). Users can customize sleep and wake-up modes. nA power consumption, therefore, suitable for low-power battery or IoT applications.
• Reliable Performance in Extreme Conditions: Functions across a wide temperature range (-40℃ to +55℃) without temperature compensation.
• Exceptional Long-Term Stability & Durability:
o Long-term zero-point stability ensures accuracy over time.
o Fast response time provides real-time detection of gas concentration changes.
o Superior linearity guarantees precise measurements.
o 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.
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.
Gases We Offer
The DS4 is available for a wide variety of gases: AsH3 (Arsine), CH4S (Methyl Mercaptan), Cl2 (Chlorine), CO (Carbon Monoxide), ETO (Ethylene Oxide), H2 (Hydrogen), H2S (Hydrogen Sulfide), HCHO (Formaldehyde), NH3 (Ammonia), NO2 (Nitrogen Dioxide), O2 (Oxygen), O3 (Ozone), PH3 (Phosphine), SMELL (Odor), SO2 (Sulfur Dioxide), TVOC (Total Volatile Organic Compounds), and more.
Revolutionizing Gas Sensing for Industrial Applications
The DS4 Digital Gas Sensor is not just a sensor—it is a complete, intelligent gas detection solution. Its compact design, smart data processing, and robust performance make it ideal for integration into IoT networks, environmental monitoring, leakage detection, industrial safety systems, and beyond.
