When is more data really better? When it is easy to gather and easy to analyze. And if recent trends are any indication, dataloggers of the future promise to be as user-friendly as a Star Trek communicator. Cheaper memory and faster, more compact components have already allowed manufacturers to design a generation of dataloggers with expanded data storage capabilities. The next generation promises to provide even greater storage capacity that will enable users to get more highly detailed information over shorter time periods (hours or days) and/or general trends over longer time periods (months and years).
Future enhancements will also include the means to more easily retrieve and analyze data. Until recently, the appeal of digital dataloggers was tempered by confusing wiring schemes and data retrieval procedures, and by blind dataloggers that could neither confirm nor deny that they were collecting valuable data. Today there are a variety of data downloading options, including RS-232, USB, and even cableless IR (infrared) and wireless transmissions. In addition, some manufacturers have developed software that eases you through all aspects of set-up and use, and collects data that easily moves to spreadsheet or graphics applications for further manipulation.
The most advanced dataloggers available todayprecursors to tomorrow's unitsutilize Spread Spectrum RF Technology, which uses special frequency bands of radio signals to transmit data over short distances between multiple dataloggers and a single receiver. This technology eliminates cabling and eliminates the need to collect dataloggers and download the data from each individually. Instead, the data from multiple remote units is automatically collected and stored simultaneously on one PC.
Next-generation dataloggers are also likely be available in solar-powered models. Most will also have additional signal inputs and direct sensor inputs, and will provide secured redundant collection with non-volatile memory. We're also likely to see a trend toward more intuitive software, and units that feature digital displays, alarm functions, and on the spot data recall and display.
Many of these same functions and technologies have already been incorporated into OAKTON® TempLog and RH/TempLog dataloggers, including:
- High-capacity memory (16,000 data points) that allows highly detailed short-term datalogging or long-term (up to two years) trend datalogging
- An LCD that shows current readings and can display recalled minimum and maximum readings
- A built-in infrared transmitter as well as a cable connection for communication with a PC or printer
- Direct temperature, pH or process sensor inputs for an additional channel of datalogging
- User-friendly software with intuitive, icon-driven features for easy datalogger set-up and data collection
- Unique flashing display alarm with high and low set points for all parameters that lets you know when to collect data indicating abnormal or unacceptable conditions
- Wireless transmitting options
