Should Your Data Logger Have A Display?
Below two parties provide evidence on why you should, or should not get a temperature, or temperature and humidity data logger with a display . . . a verdict follows.
The Case For The Display:
The case for using a data logger with a display begins at the source, the actual data logger. When you place a data logger in an environment, don’t you want to know what temperature it is reading? Why wouldn’t you? Purchasing a data logger that has a display is an investment in your application and employees. Displays allow your employees to read data at the source, and displays provide a visual ”alert” when things go wrong in your facility. Having that peace of mind, is worth it every time.
The Case Against The Display:
Our colleagues presenting The Case For The Display would have you believe that the display is essential, not costly, and at the very least, only a benefit to your facility. We would agree with them on one point: that having a display is nice. But, it does not come without costs. Displays cost more money, and they use more battery. Also, data loggers with displays are typically larger than those without. Finally, what is a data logger really used for? Logging data. Viewing data at the source is what a thermometer is for. Downloading, viewing, and analyzing the temperature data of your facility is what is truly important.
Finally, with WiFi monitoring on the upswing, displays will become obsolete.
The Verdict: A Hung Jury
The jury could not come to a conclusion, because the decision is unique to each company! Think about the two cases presented above, and make the decision based on what your facility needs!
