What is the Nexisense MS104K-S1 PortableGas Detector?
The Nexisense MS104K-S1 portable gasdetector is a high-precision, multi-functional gas detection device designedto provide early warnings of gas leaksor abnormal concentrations in industrial environments.It employs advanced electrochemical sensors andlow-power infrared technology to detect gasessuch as Carbon Monoxide(CO), Hydrogen Sulfide(H2S), Oxygen(O2),and combustible gases (EX). With its high accuracy,stability, and long service life,the MS104K-S1 iswidely used in fire fighting, emergencyrescue, petroleum and chemical industries,metallurgy, and power sectors.
WorkingPrinciple of the Nexisense MS104K-S1
Electrochemical Sensor Principle
The electrochemical sensorworks by exposing the gas toan electrolyte where a chemical reaction occurs, generating an electricalsignal. The strength of this signal is proportional to the gas concentration, enabling high-precision detection. Electrochemical sensorstypically have a lifespan of 2-3 years and are resistant to interference,making them suitable for most industrial environments.
Low Power Infrared TechnologyPrinciple
Low-power infrared sensors detect specificwavelengths of infrared light absorbed by gasmolecules. The concentration of thegas is determined bymeasuring the absorbed infrared radiation. Infrared sensorsoffer longservice life (5-10years) and high stability, makingthem ideal for continuous monitoring of gaseswith stable concentrations such as CO2and combustible gases.
Structure of theNexisense MS104K-S1 Portable Gas Detector
The Nexisense MS104K-S1 portablegas detector features a rugged, durable housing designed to withstand harshenvironmental conditions. The housing material ismade from high-strength, corrosion-resistantpolycarbonate, ensuring protection against drops, electrostatic discharge, andhigh-frequency radiation.
Shell Design
Thehousing design not only provides excellent mechanicalstrength but also offers water and dustprotection, with an IP68 protectionlevel. Whether in humid environments orareas with significant dust, the MS104K-S1 can continue tooperate reliably.
Display Screen and UserInterface
The device is equipped with a 1.7-inch LCD backlit display, showing real-timegas concentrations, alarm status, battery level, and charging status. The interface is simple and intuitive, with three buttons that allow quicksetup and operation, making it easy for field personnel to use.
Measurement Method of the Nexisense MS104K-S1 Portable Gas Detector
Diffuse Measurement
The Nexisense MS104K-S1 uses adiffusion measurement method, where gas is naturallydrawn into the detector's sensor formeasurement. This method does not requireadditional suction devices, making the detectorportable and easy to operate. Diffusion measurement ensures stable and accurate gasdetection, especially in environments where gasconcentrations change gradually.
PeriodicCalibration
To ensure the accuracy andlinearity of measurements, the Nexisense MS104K-S1supports multi-point calibration. Users canregularly perform target-point calibration to maintainthe accuracy of the device. Thedevice also features zero-point tracking toprevent zero-point drift caused by environmentalchanges, ensuring stable long-term performance.
