The Nexisense BTYQ-MS104K-S Portable Diffusion Gas Detector is a compact and highly accurate gas detection device, engineered for convenient on-site use. It supportssimultaneous detection of multiple gases, making it suitable for applications in industrial safety, environmental monitoring, chemical processing, and more. With long standby life and multi-mode alarms,it ensures safety forpersonnel inhazardous environments.
Definition
The Nexisense BTYQ-MS104K-S Portable Diffusion Gas Detector is a professional-grade portable gas detector designed to measure gas concentrations in ambient air. It features international-standard construction and utilizes advanced sensor technology to deliver real-time, high-accuracy readings formultiple gases.
Working Principle
This detector operates on the principle of diffusion-based gas detection. Gases naturallydiffuse into the sensor chamber where they are detected via electrochemical, catalytic combustion, orlow-power infrared sensors. The resulting signal, proportional to the gas concentration, is processed and displayed in real-time. Each sensor type isselected based on the target gas and its detection requirements, ensuring high precision and reliability.
Structure Analysis
Exterior Design
With a compact bodyand lightweight build, the BTYQ-MS104K-S is easy to carry and operate. Its casing ismade of high-strength material, designed to be dustproof, splash-resistant, and explosion-proof, ideal forharsh industrial environments.
Display & Interface
Equipped with a wide-angle dot matrixdisplay, it presents gas concentration, alarm status, and battery life at a glance. The interface supports both English and Chinese, improvingaccessibility for global users.
Sensor & Technology
Depending on the gas type and range, the device integrates different sensing technologies—electrochemical, catalytic combustion, or infrared. The sensor lifespan rangesfrom 2 to 5 years, and modules are user-replaceable for extended servicelife.
Measurement Method
The Nexisense BTYQ-MS104K-S Portable Diffusion Gas Detector utilizes passive diffusion toallow gases to enter the sensor for analysis. This structure simplifies maintenance and eliminates the need for external pumps. It supports gases such as CO, H2S, O2, and combustible gases (Ex).
Data Storage & Communication
The detector features large capacity data logging (up to 20,000 entries), with configurable intervals andmodes. It also supports infrared communication by default and offers optional wireless modules including Bluetooth and LORA.
Alarm System
Multiple alarm modes—audible, visual, and vibration—ensure instant alert upon over-limit detection. Alarm thresholds and modesare fully configurableto meet various application scenarios.
