Overview

The sulfuryl fluoride detector is a portable high-precision intrinsic safety product used to detect the concentration and residual concentration of fumigation gases (such as sulfuryl fluoride, bromomethane, etc.). It adopts non dispersive infrared spectroscopy analysis technology (NDIR), which can avoid interference from other gases and is widely used in the evaluation of the effectiveness of customs quarantine fumigation treatment.

Product Details

Spectros seriesSulfuric fluoride detectorIt is a portable high-precision intrinsic safety product used to detect the concentration and residual concentration of fumigation gases (such as sulfuryl fluoride, bromomethane, etc.). It adopts non dispersive infrared spectroscopy analysis technology (NDIR), which can avoid interference from other gases and is widely used in the effectiveness evaluation of customs quarantine fumigation treatment. The sulfuryl fluoride detector is a professional instrument used to accurately measure the concentration of sulfuryl fluoride gas in the environment. The following is an introduction to the equipment:

Sulfuric fluoride detectorTechnical principles and types:

1. Electrochemical sensor: achieves quantitative analysis through the proportional relationship between current intensity and gas concentration, suitable for various industrial environments, and has the characteristics of stable signal and high accuracy.

2. Infrared spectroscopy (NDIR) technology: using sulfuryl fluoride molecules to detect the characteristic absorption of specific wavelengths of infrared radiation, with high selectivity, can effectively avoid cross interference from other gases, and is suitable for wide range detection in complex fumigation sites.

3. Thermal decomposition conversion technology: For example, the DP-GF1900 instrument first converts sulfuryl fluoride into sulfur dioxide through a high-temperature furnace, and then detects it through sensors, improving the accuracy and applicability of detection.

Core functions and performance parameters of sulfuryl fluoride detector:

1. Multi mode sampling and detection: Supports various sampling methods such as diffusion and pump suction to meet the needs of different scenarios. Some models are equipped with built-in sampling pumps that can actively extract gas for analysis.

2. High precision and fast response: The typical resolution can reach 0.01ppm (low range), with short response time and fast recovery time. Some models can achieve an accuracy of ± 1ppm.

3. Alarm and data transmission: It has sound and light alarm function, supports local LCD display and remote transmission, and can be connected to PLC, DCS system or cloud platform through wireless or wired means.

4. Explosion proof and protective design: It generally has explosion-proof certification and is suitable for hazardous areas; High protection level, suitable for dusty and humid environments.

5. Additional functions: Some models integrate temperature and humidity measurement, data storage, Bluetooth printing, and other functions to improve on-site operation convenience.

Sulfuric fluoride detectorMain application scenarios:

1. Monitoring of the entire fumigation process

-Dosing stage: Check the uniformity of high concentration sulfuryl fluoride distribution to ensure insecticidal effect.

-Leakage monitoring: Monitor the surrounding environment during fumigation and sealing to prevent gas leakage.

-Safety confirmation after venting: Verify whether the residual concentration is below the occupational exposure limit to ensure personnel safety.

2. Grain storage and port quarantine: used for fumigation treatment and residue detection in grain warehouses, containers, archive warehouses, and other places to prevent the spread of pests and bacteria.

3. Industrial safety and environmental protection: Monitor toxic gas leaks in chemical production, or use it as an environmental safety assessment tool in emergency accidents.

4. Scientific research and laboratory applications: Evaluating the effectiveness of fumigants in plant quarantine research or for environmental simulation experiments.
