Vegetable processing methods There are methods such as canning, drying, pickling and quick freezing. The canning of vegetables is to put pretreated vegetables such as cleaning, peeling, cutting and blanching into sealed containers such as tinplate cans and glass bottles. A method of killing or inhibiting the growth of microorganisms in order to preserve vegetables for a longer period of time. Drying is a processing method that uses heat to dehydrate vegetables, that is, natural drying or artificial drying to increase the concentration of soluble substances in vegetables to a level that is difficult for microorganisms to use.

1. Correct the demand correction method, duration, and ease of use. There are two types of calibration methods—laboratory and on-site calibration. On-site calibration is the exhalation of the oxygen sensor. The oxygen reading of the instrument must be reduced and an alarm must be generated.
2. Reliability Gas detector The longer the sensor life, the better. In general, the sensor life is at least 2 years, and the flammable gas sensor is 2 to 5 years. The longer the average error time, the better. What is the accuracy and precision? The smaller the error, the better. The product warranty period is generally 2 years.
3. Applicability The identification and assessment of the hazardous gas at the site where the limited space operation is carried out shall be performed by the company's professional staff and experienced field supervisors or employees to determine whether the selected detector's sensor meets the requirements for use.
4. What is the value of the zero offset and full amplitude offset of the stability detector? The smaller the better.
5, convenience, light weight, small size, easy and comfortable wear, easy maintenance.
6, easy to identify numerical or pointer gas detector. In general, numerical models have the advantages of easy reading and less misjudgment. The display area is large enough, with background lighting and large fonts to facilitate reading and understanding. Whether the siren is large enough to distinguish it from background noise. It is generally effective at 90dB (A) or more. Whether the alarm flash can be recognized from various angles. Is it possible to continuously display the signal with changes in the measured gas concentration, and to stop the alarm after confirmation or countermeasures are taken.
Gas detector cannot be omitted
Did you notice the choice of gas detector? How to choose according to the environment? How to choose according to space? How to choose according to gas? Regardless of the reasons we choose, we must pay attention to the following points:
