A recorder is an instrument that converts one or more variables over time or changes in another variable into identifiable and readable signals. It can save the recorded signal changes for analysis. The logger's biggest feature is the ability to automatically record slow or non-periodic multi-signal slow-moving processes and transient level changes.
There are many kinds of recorders for environmental monitoring, such as soil temperature and humidity, CO2 concentration, atmospheric temperature and humidity, soil nutrients, light intensity, etc. Meanwhile, the recorder is also used in many aspects, such as the driving process of the car and others. Each of the loggers manufactured by Top Instruments is capable of performing periodic setups for recording. The record time of different types of records is not equal, for example, the recording time of the soil temperature and humidity recorder can be arbitrarily set, and the recording time of the rain recorder is: 2 seconds to 24 hours continuously adjustable. At the same time, the data storage of each recorder is different. For example, soil temperature and humidity recorders, moisture storage data: 5000 groups, and rainfall recorder data can store up to 60,000 data (two parameters are 30,000 groups, three The parameters are 20,000 groups, the four parameters are 15000 groups, and so on.
Loggers can be divided into paperless recorders and paper recorders, paper recorders with unique thermal printing methods and advanced microprocessor control technology to achieve unparalleled high recording resolution, high precision, and high reliability , versatile and easy to operate. Continuous recording and digital printing. Widely used in medicine, petroleum, chemical, metallurgy, electric power and other industries and research institutes. The disadvantage of having a paper recorder is that it is expensive. A large part of our company's sound field record is a paperless recorder. Its advantages are that it is convenient to carry, simple to operate, and stable in performance. However, it has certain limitations in measurement.
