Data loggers are small electronic devices used to track and store location-specific data via built-in or external sensors. They are typically battery-powered and equipped with internal memory, and have become the predominant method of monitoring in most contemporary industries, having increasingly replaced the electromagnetic chart recorders that originated back in the early 19th century.

Data loggers are used in a variety of industries and applications that require critical monitoring of environmental variables such as temperature, humidity, and pressure in order to produce and maintain a safe product. These include, but are not limited to, the healthcare industry, manufacturing, aerospace, and food/beverage production and storage.

Below we introduce you to the basics of data loggers, including why they are important, how they work, where they are used, and how to select the right data logger for your business.

Why Data Loggers Are Important

Data loggers are critical when it comes to demonstrating compliance with industry-specific regulations and standards. When implemented correctly, they provide data that can be used to either establish compliance or reveal hidden problem areas to address.

You can then further analyze the data using software to enhance quality and performance, track down problems before they become serious, and visualize data to illuminate trends and fluctuations. In addition, data loggers are key in conditions where there are quality and environmental controls in place, including highly sensitive, dangerous, or otherwise critical environments. Modern data loggers can also work in concert with cloud-based remote monitoring systems to keep you informed of your environment even when you’re not there.

Failure to use data loggers in a sound and systematic manner can, depending on the industry involved, result in time-consuming investigations, hefty fines, and expensive lawsuits. This can also impact those working in research, causing results to come under scrutiny and impact the reputation of individual research or research groups.
