Gas Detection & Monitoring

The NDIR gas sensor is a high-performance gas detection solution that uses advanced non-dispersive infrared technology to deliver accurate and stable detection of combustible gases such as methane (CH₄), propane (C₃H₈), and isobutane (C₄H₁₀). It supports measurement ranges of 0 ~ 10% VOL, 0 ~ 15% VOL, and 0 ~ 100% LEL (optional). With high selectivity and no cross-sensitivity to other gases, this SISCO infrared gas sensor ensures reliable performance in critical gas detection and leak monitoring applications.

CO, temperature, humidity, altitude, and atmospheric pressure can be measured in this multi function air quality monitor. Clear digital display, loud audible alarm and visual warning indicator alert you immediately when dangerous levels are detected. Easy to carry and use, portable co detector good for bedroom, kitchen, rv, and climbing.

Home air quality sensor is a compact indoor air quality monitor. It features a high-precision sensor updating CO2, PM2.5, PM10, temperature and humidity every second. The OLED display supports slide and tap controls. This smart air quality monitor integrates Apple HomeKit with a multi-color air quality indicator.

The SISCO travel carbon monoxide detector is a practical and multi-functional monitoring device. Its core function is to detect methane/liquefied petroleum gas (LPG) concentrations from 0~8000 ppm and carbon monoxide concentrations from 0~999 ppm. It also features temperature and humidity monitoring capabilities, operates on AC 100~240V power, and boasts an intuitive LCD screen and multi-level concentration color bars. It is ideal for installation in bedrooms, living rooms, or vehicles, providing practical environmental safety alerts for daily travel and home life.

The SISCO portable carbon monoxide detector is a portable and practical gas detection device. Its magnetic attachment and lanyard hole design allow for flexible placement and portability. The battery lasts up to 5 days, meeting short-term continuous testing needs. The device supports one-button switching between Celsius and Fahrenheit temperature scales and allows for customizable carbon monoxide audible alarm thresholds. When levels exceed the limit, a flashing red and yellow light combined with a buzzer provides a dual visual and audible alarm. The operation is simple, and the prompts are clear, making it suitable for various daily testing scenarios.

WiFi air quality sensor adopts semiconductor and infrared particle sensors. It detects CO2, HCHO, TVOC, PM2.5, PM10, CO, and AQI. Measurement ranges cover CO2 400-5000PPM, HCHO 0-1.99mg/m3, TVOC 0-9.99mg/m3, and PM2.5/PM10 0-999ug/m3. CO2 sensitivity is 1PPM, while PM2.5 sensitivity is 1ug/m3. A smart WiFi APP allows remote monitoring, real-time data viewing, and history curve checks. It also supports alarm threshold settings through the APP.

IoT air quality sensor measures PM2.5 and PM10 with a range of 0~1000 μg/m3 and a resolution of 1 μg/m3. The laser scattering principle ensures ±10% accuracy. It outputs an RS485 Modbus RTU signal to a PLC, features a waterproof, wall-mounted housing, fast response ≤30s. Its wall-mounted design simplifies installation. It also has a 10- 30 VDC power supply, < 60 s warm-up time, and operates from -10°C to +60°C.
