If you’re ever here at Opto 22 (perhaps for our free training) you’ll see ICTD probes throughout the building where we’re using our own hardware to monitor and control the HVAC system, lighting, etc.
I know may of our customers use them for a variety of purposes, I hope folks will share here. Perhaps you might share more details about what type of environment you’re measuring temperature in, so other can provide more detailed opinions and suggestions?
This white paper (form 1767) describes various temperature sensors such as RTDs, thermocouples, ICTDs, thermistors, and infrared sensors, and the Opto 22 solutions for using them.
I hope that helps!
