Data loggers are electronic devices designed to record data over time or in relation to location. Understanding how these devices work will help make your data logger selection process less daunting. Moreover, “choosing the right model and type is crucial for ensuring accuracy in your applications”, say data loggers Australia industry experts. For that reason, we offer you some tips on how to buy the right data logger according to experts’ opinion.
Measurement Accuracy
Regardless of your measuring application, understanding your measurement accuracy requirement is extremely important. For example, for monitoring the air-conditioning temperature in an office space, you may only need a temperature measurement accuracy of +/- 2 degrees, while for monitoring conditions in a research lab, you may need a far greater accuracy.
According to the data loggers Australia industry experts, accuracy specifications tend to vary between different types of data loggers, hence understanding well specific accuracy requirements will help you avoid paying for unnecessary accuracy. You should look for charts that indicate accuracy over a total measurement range, not just a single value.
Data Access Options
When looking for data loggers, it is a good idea to get familiar with the available options for accessing the collected data. With stand-alone data loggers, data is transmitted to a computer via USB interface. However, in many cases having to bring a computer out to a site may be unpractical. In that case, a pocket-sized device called ‘data shuttle’ can be the right solution. There are also wireless sensor networks that transmit highly accurate real-time energy and monitor data from different points to a central location.
Software Capabilities
Data loggers come with different types of data graphing and analysis software packages. Generally speaking, you should look for software that is Windows® and MAC-based. The software should allow you to easily and quickly perform tasks such as launching the data logger, configuring parameters and offloading data.
Durability
Just like with test and measurement equipment, when purchasing a data logger, make sure that the device is designed to withstand the conditions of the environment it will be used in. You should also ask for protective cases and other accessories for situations where durability and protection may be needed.
Battery Life
Usually, data loggers are extremely low-power devices. However, because they are used in diverse environmental conditions, their battery life can vary greatly. It is a good idea to choose a data logger that has a battery life of at least one year.
