Introduction, types and selection of temperature and humidity data logger

Temperature and humidity data logger are widely used in all walks of life in the country, such as agricultural scientific research, food safety, pharmaceutical storage, chemical industry, environmental protection and other industries. The temperature and humidity recorder is mainly used for temperature and humidity monitoring and recording of food, medicine, and fresh items during storage and transportation.

What is a temperature and humidity data logger?

A temperature and humidity data logger is a temperature and humidity measuring instrument. Built-in temperature and humidity sensor or external temperature and humidity sensor probe. The recorder is mainly used to record the temperature and humidity data of refrigeration, vaccines, food and fresh food during storage and transportation, and save the data records in the equipment. Usually, temperature data loggers also have a PC data upload function that can be used for data viewing and analysis. The temperature and humidity recorder can perform curve analysis through the data platform, and save the output data as a PDF file.

How to choose the best temperature and humidity data logger? First, choose the built-in temperature and humidity sensor or an external temperature and humidity sensor to measure temperature data according to your own needs.

According to the classification of recording media, it can be divided into two types: paper and paperless.

1. Paper temperature and humidity data logger

It directly records the collected temperature, humidity and other data on the recording paper, which requires the use of recording paper, writing pens and other consumables, and the data is saved through the recording paper. Compared with the current electronic temperature and humidity recorder, the paper temperature recorder is bulky and inconvenient to use. It is necessary to check the recorded data through the recording paper, and only the approximate trend changes can be viewed according to the values ​​and curves on the recording paper. Due to the limitation of its mechanical transmission structure, the paper temperature and humidity data recorder can only be equipped with less functions such as alarm output, and there cannot be too many input channels, so it is rarely sold in the market.

2. Paperless temperature and humidity data logger

Adopt microprocessor, display screen and memory. Some industrial site environments are more complex, and traditional products cannot meet the needs. Paperless recorder with short thickness, high integration, rich colors, comfortable operation, complete functions, high reliability and good cost performance. Large recording capacity; recording interval from 2 seconds to 255 seconds. Products are widely used in petroleum and petrochemical, chemical, pharmaceutical, biological, scientific research, calibration, temperature and humidity measurement and other industries.

With the development of computer and Internet technology, the paperless temperature and humidity recorder has quickly occupied the market with its more accurate data recording, more convenient data storage, and more convenient data analysis functions.
