在食品安全,冷鏈運輸,工業,公共建築等領域，可能有必要測量涉及環境空氣的數值。除了溫度和濕度外，二氧化碳數值也可提供關於室內空氣品質的資訊。為了確保合理的室內空氣品質(IAQ)，您需要定期瞭解這些數值的變化情況。
還有可用來測試特定產品最佳條件的資料記錄儀。尤其經常使用溫度資料記錄儀，USB型資料記錄儀操作方便。
資料記錄儀
如果您想購買一個或多個資料記錄儀，在選型時有各種影響因素：
- 可以使用測量儀測量哪些數值？
- 測量值的準確度如何？
- 是否可以重複測量？
- 可充電電池的使用壽命有多長？
- 使用測量儀時是否產生後續成本？
- 測量儀附帶哪些軟體？

Ideal data loggers for every application
Data loggers - the reasons why they are so important
The question of whether data loggers should be integrated into a system or rooms depends on what the rooms are used for. Many people are active in schools, nursery schools and also in office areas on a daily basis. The rooms are often only very small in size. A high concentration of CO₂, incorrect humidity or temperatures that are too high or too low may have a strong influence on well-being. However, if it is possible for you to check these values, you can respond quickly. A temperature and humidity data logger therefore offers you the option of detecting when the humidity is particularly high or low. You get an alarm if the temperature rises too high. This means you can create an effective ventilation plan.
Particularly in industry, the data logger takes pressure off the constant checking of temperature and gas exposure in day-to-day work. You have the possibility of providing the data recorder with limit values. When buying the instrument, make sure that it gives you an acoustic warning when the limit values are exceeded. That may for instance be particularly important for a cold chain.
The accuracy of the measurements has a role to play for the instrument when you only have small margins in terms of the values. When goods are easily perishable or very sensitive, instruments must measure considerably more accurately than when controlling office areas. The service life of the rechargeable battery is also an important aspect. Data storage should also still be ensured even when the instrument no longer has a power supply. A complete data monitoring system is a particularly practical option. It is designed so that the data are transmitted directly to a terminal device. That gives it various advantages:
- precise checking of values
- time and cost savings
- transmission of data by radio or also via Ethernet
- acoustic alarm if the values are exceeded
Data recorder: the different versions
There are different data logger designs. Use of the data logger for temperature measurements is particularly well-known and frequent. However, there are also other versions which it may make sense to use. One of these is the CO₂ data logger. It is able to measure the gas concentration in the air. The CO₂ data logger can be of particular interest in areas where many people work, or also learn, in a small space. It indicates when it is sensible to ventilate the rooms.
UV intensity can have an influence on quality, in particular when storing goods, for example in logistics. Measurement is possible using a UV data logger which can be fitted in the rooms. Just like UV intensity, impacts and vibrations can also lead to damage, for instance during transport. The shock data logger can provide information about these activities in this area.
- It may make sense to use multiple dataloggers
- Measurements of temperature, CO₂ concentration or shocks are possible
- Detailed measurement results
The data logger's data transmission
You will find different data loggers at Testo, which means you can ensure the areas where you want to carry out measurements are equipped in the best possible way. The focus here should be on accurate measurement results, which are important for data analysis. The question of how the data can be transmitted for analysis is also an interesting one. The security of the data and the repeatability of the measurements are an important factor too. There are two different versions when it comes to data transmission and using the instruments:
USB data logger
The USB datalogger is very popular to use, because in most cases it can be quickly recharged and it provides optimum measurement data security. This form of data logger also already has a calibration certificate and a configuration file. This makes it possible to generate the data directly on a terminal device in a PDF file and then to print this out. The analysis can then be done straight away. The advantages of the data logger are particularly practical
- generation of PDFs on the terminal device
- very flexible operating time
- easy to use
- already includes a configuration file
WiFi data logger
The radio data logger is another possible version. It may make sense to work with wireless LAN, particularly when you want to use data measurement to check either several areas or larger ones too. The data are transmitted to a chosen terminal device and you can keep an eye on all the areas. This means you save both time and costs.
