Tips on Buying a Data Logger

data logger

Data loggers perform an important function in maintaining the appropriate environment for people, goods and equipment.  They also serve to collect data from monitoring equipment such as weather stations or to observe vehicle and machinery performance.

These versatile electronic devices work by independently monitoring and recording specified environmental parameters from a fixed location over a chosen period of time.  They have the capacity to collect data on a 24-hour basis unattended, providing an all-inclusive, precise and real-time picture of the environmental conditions being observed.

With increased technological capacity, the collection of the data recorded by the data logger has moved from a manual task to rapid transference of information via an internet connection. Sensors placed in the equipment measure the conditions required, for example a temperature logger is used to monitor conditions for equipment and goods that are affected by heat and cold.

What should businesses look for in a data logger?


When purchasing your data logger, make sure to choose the device that meets the conditions it is intended for – protective cases and ruggedized equipment are available for harsh conditions.  For data collection in difficult conditions certain data loggers are designed to be resistant to problems such as program crashes and operating system instability that might affect a general-purpose computer. In milder indoor environments, a less hardy device will do the job perfectly. 

Memory card or real time transmitting

If your data logger needs to be left in a severe or remote environment that is out of range of a wireless connection such as a water tank or piping, a ruggedized USB stand-alone logger is probably your best choice.

For more convenient locations, web-based systems or Bluetooth data loggers provide instant data and analysis as well as providing alerts that can save massively on repairs and replacement costs for equipment.

Know your requirements

Data loggers are designed for different measuring capabilities. The devices can use just one input channel or reach up to 100 depending on the limitations of the power source. As well as temperature loggers, sensors can collect voltage, current, water pressure, hydraulic pressure, flow rate, speed, wind speed, wind direction, rainfall, solar radiation, GPS data and much more.

The parameters and data  you require will determine the sensor type and accuracy required.

How many sensors are required and the level of accuracy desired will determine the resolution of the data logger you need.

Power source

Because data loggers are left to do their job independently for long periods of time, they need an independent power source that is reliable and long lasting.  Lithium-ion cells provide an option for long lasting and versatile power.

Solar power is another option for data loggers that perform their task in remote locations and harsh conditions that may be hard to reach.

Before choosing a data logger from the vast variety of options, consider your requirements, location and budget.  Take some time to consult with an expert who can guide you to the device that will work best for your business.

You can buy a high quality data logger from most reputable distributors like global parts supplier, RS Components. With a range of types and models available, from temperature loggers to humidity data loggers, you’ll be able to find the perfect fir for your organisation.
