What is a multichannel datalogger?
A datalogger is an electronic device for recording data over time. Dataloggers are used to observe waveforms that are digitally processed and recorded; they can be designed to monitor one physical quantity or several quantities at once on several channels - so-called multichannel dataloggers.
A multichannel datalogger is therefore a device designed to simultaneously measure and record data from several different sensors or measurement points. Each channel of the datalogger is connected to a separate sensor, which allows monitoring of different variables such as temperature, humidity, pressure, voltage or current at multiple points at the same time. This makes it possible to monitor complex processes and analyze the interdependencies of the measured parameters.
The functioning of the multi-channel datalogger is based on the fact that it periodically takes readings from each channel and stores these values in internal memory or transfers them to a computer or cloud storage for further analysis. Some models also offer wireless communication, making it easier to collect data from hard-to-reach locations.
On our website, we offer Hioki dataloggers that have a maximum sampling rate of up to 1000 samples per second (1000 Hz), making them suitable for observing signals associated with slower phenomena. For faster sampling speeds, Hioki offers so-called Memory HiCorders. The fastest sampling is achieved using oscilloscopes (e.g. Tektronix), but these do not allow such long data recording.
