Greetings!logo old

It has been a busy year so far at Dickson, updating our existing products, as well as releasing brand-new instruments to simplify and enhance your monitoring experience. We understand how important it is to have the most accurate data, exactly when you need it, even when your instrument is due for calibration. It is our goal to take the hassle out of re-calibrating your Dickson Data Loggers! To make this a reality we have developed what we call a Pre-Calibrated Sensor, or PCS for short.

The Pre-Calibrated Sensor is:

  • User Replaceable - rather than taking the time to return your unit to Dickson for re-calibration, you can simply purchase a new pre-calibrated sensor to replace your existing sensor. 
  • Affordable - Save money by not paying for shipping back your instrument and taxes.
  • Convenient - You will never be without your monitoring device or lose any critical data. When you get the replacement, simply remove the old sensor and pop on the new one!


PCS and DicksonOne Logger

This new sensor is simple, quick, and cost effective.  Feel free to email or call today to find out more information about our PCS compatible instruments! The PCS is a temperature or temperature & humidity sensor that is calibrated in our accredited laboratory and is compatible with our new Touchscreen and WiZARD2 Wireless and Ethernet Data Loggers.
