Temperature Data Loggers and Recorders

Temperature Data Loggers allow you to monitor and record temperature values over a period in time. The data is typically viewed using software that, in most cases, is available as a free download. The data logger software gives you a time date stamp for each data point which is viewable as a graph, raw data file, or PDF report.


Data loggers are superior to traditional chart recorders as they are typically much smaller in size, don’t use consumables (paper charts), and because the data is recorded as a data file, there are no paper charts that have to be stored. Where typical chart recorders can only record up to around 30 days most digital data loggers can record anywhere from 6 months to over a year. Being an electronic file also makes it much easier to share your data with others.

Data loggers are available in a wide variety of styles, from simple direct connect USB loggers to wireless loggers that can send remote notifications of alarm events and automatically send data to a cloud service. There are temperature data loggers for outdoor use or even underwater. MicroDAQ, LLC offers a large selection of loggers ensuring that we probably have multiple options for almost any application. Our Technical Sales Representatives are available by chat, email, or phone and they are always happy to help you find the best solution for your particular application.
