Let's give you a quick idea of how to buy a smoke analyzer.

    Even though there are many brands of flue gas anatomy, both abroad and within the country, and you've been too busy to pick out the smoke anatomy, so why do you choose to import the smoke anatomy?

    Portable pneumatic anatomy units are currently available on the market, usually in combination with electrochemical and infrared.

    Here's a brief description of how to select a smoker:

    1. Sensors:

    The measuring units that are touched by the current dry flow flue gas profiler consist primarily of two sensors:

    1) Electronic chemical sensors:

    Strengths:

    a Small size: so handheld machine type, generally electrochemical.

    b Cheap: a flue gas anatomy machine capable of acquiring electrochemical sensors at a cheaper cost if the budget is lower.

    Deficiencies:

    a A slight deviation in accuracy: General error at > 5 per cent of the reading, only meeting national environmental standards.

    b Cross-disturbing: Electro-chemical sensors are simply disturbed by other gases, increasing miscalculation of results.

    c Life spans are short: life spans are usually 2-3 years, so replacement is always considered.

    2) Non-dispersible infrared sensors:

    Strengths:

    a Quantification is accurate: the general test results do not exceed 2 per cent of the full range and are capable of being used as a precise instrument for profiling.

    b There is no cross-disturbing: other gases will not be subject to testing of infrared sensors for measuring reasons.

    c Length of life: Infrared sensors generally do not have the concept of longevity, are used for a very long time, usually for more than 10 years, and do not require special protection on a daily basis, and are now gradually becoming dry stream sensors.

    Deficiencies:

    a Prices are slightly higher: prices are typically several to ten times higher than those of electrochemical sensors.

    2. Sampling systems:
