Data Logger
Data loggers are?electronic devices which automatically monitor and record environmental parameters over time, allowing conditions to be measured, documented.
A?data logger?is any device that can be used to store data. This includes many data acquisition devices such as plug-in boards or serial communication systems which use a computer as a real time data recording system. Nowadays, wireless transmitters are also capable of turning a regular smart phone (or tablets) into a?mobile data logger.
Most instrument manufacturers, however, consider a datalogger a stand alone device that can read various types of electrical signals and store the data in internal memory for later download to a computer.
The advantage of data loggers is that they can operate independently of a computer, unlike many other types of data acquisition devices. Data loggers are available in various shapes and sizes. The range includes simple economical single channel fixed function loggers to more powerful programmable devices capable of handling hundreds of inputs.
Choosing a Data Logger
When choosing a data logger the following parameters should be considered.

Input Signal
OMEGA offers data loggers that are compatible with most types of signals. Some data loggers are dedicated to a certain input type while others are programmable for different types of inputs. OMEGA offers a wide range of data loggers for several types of signals, including thermocouple, sound, pH, pressure and many more (see the "Types of Signal" for a list).
Number of Inputs
Data Loggers are available in both single and multi-channel designs. A?32 channels data logger?such as OMEGA OM-SQ2040 Series is capable of handling multiple inputs.
Size
In many applications space is a limitation. In those cases the size of the data logger may be a critical selection parameter. OMEGA's OM-CP family of data loggers are extremely compact and include models for most input types.
