National/local policies: At the end of 2019, new limit     standards were introduced, and government departments such as occupational defense institutes also increased supervision. And at the beginning of 2020, the country began a new year of occupational health surveys, increasing the requirements for monitoring. Higher quality control requirements are put forward for on-site sampling.

In order to facilitate the wearing of individual samplers, and to achieve rich management functions, in response to strict quality control requirements. Design intelligent wearable accessories, and use IoT boxes to realize functions such as data upload, collaborative control, and trajectory tracking of occupational health individual sampling; Cooperate with the sensor module to realize the application of safety supervision leakage detection, fire safety and other fields.

Product positioning: mainly for the market for government supervision units and large-scale Grade A occupational health units, such as: CDC, occupational prevention hospitals and other departments.

User positioning: This sampler can collect samples of harmful gases in the air for a short or long time for environmental monitoring stations, health and epidemic prevention, labor protection, CDC, engineering quality indoor testing, scientific research units, colleges and universities, industrial and mining enterprises environmental protection personnel.

User experience: Individual sampling, the instrument needs to be carried on the body, and the enrichment tube is placed in the respiratory belt for sampling, short-term sampling for 15min, long-term sampling for 1 hour. This instrument adopts ultra-small design, which is more suitable for personnel to wear and is suitable for, and has the characteristics of light weight and long battery life. And fine control of the low range range, basically cover the organic gas collection flow requirements, more convenient to use.

Application scenarios: mainly used in occupational health personal poison sampling work, sampling needs to be worn on the individual, follow the movement of the person and move, and in most cases need to be worn by multiple machines. The sampling line should be placed on a personal breathing belt to simulate a human breathing scene. And during the wearing process, it should not affect the normal work of workers. For more management needs, equipped with IoT boxes.

The instrument uses a flow range of (10~300)ml/min, a resolution of 1ml/min, strong load and endurance, explosion-proof certification, and has passed various harsh environmental test tests, and optional intelligent straps to achieve data management.

Safety supervision leak detection: The multi-functional intelligent strap and pump suction sensor module can carry out manual navigation leak detection, and alarm can be made when the leakage point is encountered.

It has an automatic calibration function and can be adapted to different flow calibrators.

The strap should have anti-static, flame retardant and other characteristics, suitable for wearing in explosion-proof occasions.

The harness line should be hidden and the air intake should be close to the breathing belt.

The strap should cooperate with the host to achieve anti-disassembly function, and the abnormal disassembly status of the IoT box can be recorded:

Positioning capabilities. (Movement trajectory recording function)

Abnormal status recording and saving function

There should be LEDs to indicate connection and working status

Multiple IoT box networking collaborative control function

Supporting APP, data monitoring and control functions.

Up to 4 individual samplers can be connected simultaneously and data status can be controlled and monitored collaboratively.

Data can be uploaded to the platform for easy data traceability management.

Multiple simultaneous automatic calibration can be realized and calibration records can be formed.

Meet the Ex Ib II bT4 Gb explosion-proof and coal safety explosion-proof requirements, and the sensor module is small in size and should be mounted on the strap

Up to 8 types of gas sensors can be mounted, which can be freely matched and should be versatile
