Should Your Data Logger Have A Display?

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!

    My perspective is based on a pharmaceutical analytical testing laboratory (room) or process room setting. Loggers with display is effective if/when an analyst needs to record current room conditions during a specified analysis/process. This is obviously like having a thermometer in the room. At least there’s no need to calibrate a secondary equipment (thermometer) if only requiring a data logger! This is a case where we argue the difference between monitor (reading) and controlling (reading and adjusting – like a thermostat).

    When used in stability chambers, who cares what the current display reading is. The absence of an alarm = all is within specification!

    In the end, if it is cheaper to build and sell loggers containing displays as the only purchase option, there’s no harm in “to much info”.

      Thanks for the comment Jeff! We couldn’t agree more on your last point. The only issue, is that including a display does sometimes cost more, they do tend to take up more battery life, and the creation of a display makes the product at the very least, slightly larger. For the most part, if cost and logger specs are the same, the display really can’t hurt you.
