Important Considerations in Buying a Data Logger

Battery-powered data loggers are widely used by performance contractors, service technicians and engineers responsible for monitoring indoor air quality, evaluating HVAC/R (Heating/Ventilation/Air Conditioning/ Refrigeration) systems, and monitoring energy efficiency and usage. Data loggers, in most cases, are easy to deploy, and can be used as standalone devices without a PC. More importantly, the measurement accuracy offered by today’s most advanced data loggers rivals the performance of many higher priced, PC-based data acquisition systems.

However, not all data loggers are created equal, and with so many choices available today, it can be challenging to know which one is right for your application. Do you need to measure a range of conditions, or just a single parameter? Does your application require alarm notification when conditions go beyond a certain threshold?
