Overview
SKYEAGLEE SK/MIC-800-NO-Y/2000 Portable Nitric Oxide Detector is a high-performance Handheld Gas detection device. The instrument adopts imported High Accuracy Electrochemical sensor, combined with professional circuit design and ultra-low power 32-bit ARM processor, to ensure fast, accurate and stable detection of nitric oxide gas. The instrument is equipped with a 3.5-inch full-color TFT display, supports Chinese and English graphic menu operation, built-in micro sampling pump, and has explosion-proof, waterproof and dust-proof design, suitable for a variety of industrial environments.
Features
1. Imported High Accuracy Electrochemical sensor to ensure accurate and reliable measurement.
2. Use High Accuracy Low Temperature Drift Amplifier and Stable Power Processing Circuit to Ensure Long-term Stability.
3. Equipped with a 3.5-inch full-color TFT display, it supports Chinese and English graphical menus and real-time trend detection.
4. With large-capacity Data storage function, it can store up to 300,000 sets of data, and the storage interval is adjustable.
5. Support USB interface for high-speed data transmission, which is convenient for data download and printing.
6. Built-in imported long-life micro sampling pump, providing low, medium and high adjustable cleaning air circuit functions.
7. Through explosion-proof certification, Explosion-proof level is Exia II CT4, and the shell is designed with a two-color mold that is non-slip, waterproof, dustproof and explosion-proof.
8. With self-calibration, zero/multi-point calibration, temperature and pressure compensation, one-button factory reset, self-programming alarm parameters, STEL/TWA calculation and other functions.
9. Provide two Operating Modes of Normal Detection and Patrol, the gas circuit has an automatic cleaning function, and automatically prompts the fault and Sensor status.
Principle
The detector uses a pump-suction Sampling method, and the environment gas is sucked into the inside of the instrument through a built-in micro-sampling pump. The gas contacts the Electrochemical sensor at the core of the instrument, and the Sensor generates a corresponding electrical signal based on the concentration of nitric oxide. The signal is amplified by a High Accuracy, Low Temperature Drift amplifier, processed by a stable power processing circuit, and finally calculated and converted into a gas concentration value by a 32-bit ARM processor, which is displayed on the screen in real time. The instrument has temperature and pressure compensation functions to correct the impact of different environmental conditions on the measurement results.
Applications
Industrial safety monitoring, environment monitoring, confined space operation, chemical production, metallurgy, fire emergency, municipal pipe network maintenance
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will warm up for about 30 seconds.
2. Select mode: Select "normal detection mode" or "patrol mode" through the menu.
3. Set the sampling gear: Select the low, medium or high level of the sampling pump as required.
4. Start detection: The sampling tube is inserted into the area to be tested, and the instrument automatically samples and displays the real-time concentration.
5. Data viewing and export: You can view historical data, STEL/TWA values through the menu, and connect to the computer through the USB interface to export data.
6. Calibration and settings: Regularly perform zero or multi-point calibration through the menu, and can program alarm parameters and other functions as required.
Notice
* Please use it within the valid period of instrument calibration and perform Sensor calibration regularly.
* Avoid prolonged use in extreme temperatures (beyond the -30~ 50 ℃ working interval) or high Humidity condensing environments.
Instruments are explosion-proof, but must not be disassembled or charged in hazardous locations beyond the Explosion-proof level.
After use or when not in use for a long time, it is recommended to clean the gas path.
Pay attention to the fault information prompted by the instrument and deal with it in a timely manner.
Avoid strong impact or immersion of the instrument in liquids.
* When replacing Sensors or performing repairs, it needs to be operated by a professional.
