Handheld VOC detector PID photoionization detector investment promotion

Description :

　　Industry applications of VOC detectors:

　　Refining and petrochemicals, manufacturing of chemical raw materials and products, manufacturing of chemical raw materials and drugs, manufacturing of synthetic fibers, surface coating, printing, shoemaking, furniture manufacturing, artificial board manufacturing, electronic component manufacturing, textile printing and dyeing, plastic manufacturing and plastic products, life service industry, etc.

　　Characteristics of VOC detector:

　　1. Continuous sensitive measurement: PID can detect organic compounds in real-time at concentrations as low as PPb (parts per billion). Specially suitable for the health and safety needs of modern petrochemical, labor hygiene, environmental monitoring and other departments;

　　2. Fast: PID has a fast response time, usually less than 3 seconds, suitable for quick emergency needs;

　　3. Portable measurement: The instrument is small in size and light in weight, and can be carried to any location that needs to be tested. The built-in powerful suction pump can suck up the gas to be tested that is difficult for personnel to reach;

　　4. High safety: The instrument is inherently safe and does not require hazardous carrier gases such as hydrogen;

　　5. Wide adaptability: capable of detecting the vast majority of organic substances within the concentration range of 1 ppb to 10000 ppb;

　　6. Non destructive measurement: Since PID only ionizes organic matter, it will recombine after the organic components leave the detector. Therefore, users can use the powerful suction pump of PID for sampling operations and further laboratory analysis of the tested samples;

　　7. Sensors will not be poisoned: Unlike most other principle based detectors or sensors, PID detectors that use optical principles will not be damaged by high concentrations of the tested substance.

　　Product features of VOC detector:

　　1. The magnification factor of the display value can be set, and it can be restored to normal after restarting;

　　2. High precision, high resolution, fast response;

　　3. The whole machine has a small volume, light weight, waterproof, explosion-proof, and shockproof design;

　　4. High precision, high resolution, fast response;

　　5. Safe and portable device with built-in micro gas pump;

　　6. Digital LCD backlight display, sound and light, vibration alarm function;

　　7. Data recovery function, eliminating worries caused by misoperation;

　　8. The shell is made of special materials and processes, which are not easy to wear and tear, easy to clean, and bright as new after long-term use;

　　9. The upper and lower limit alarm values can be set arbitrarily, with built-in zero and target point calibration functions, built-in temperature compensation, and easy maintenance;

　　10. Using high-capacity rechargeable lithium batteries, it can work continuously for a long time.

　　The use of VOC detectors in confined spaces:

　　When using VOC detectors in confined spaces, attention should be paid to flammable and harmful gases, such as reaction tanks, sewers, ship cargo holds, underground facilities, and other environmental environments. Before entering a sealed environment, testing must be conducted. In this situation, it is necessary to choose a detector with a suction pump, because in a closed environment, due to the lack of air circulation, gas diffusion is slow, and the gas distribution in different parts varies greatly. For example, combustible gases have a lighter mass;

　　Most of them are distributed in the upper layer of enclosed spaces, where carbon monoxide has a mass similar to air and is generally located in the middle layer of the enclosed space. Heavier gases such as hydrogen sulfide are located at the bottom of the enclosed space. In addition, considering the hazardous gases in enclosed spaces, a built-in suction pump should be used for non-contact long-distance detection of multiple gases. At the same time, it is easy to carry and does not affect workers' work, so as to ensure the safety of personnel entering enclosed spaces;

　　In addition, after entering a sealed environment, it is necessary to continuously detect the internal gas to prevent leakage and changes in hazardous gas concentration caused by temperature and other factors.
