These sensors measure temperature and humidity, then send the measurements to your PLC or controller to regulate heating and cooling equipment, alarms, and data recorders.

Touch the tip of your soldering iron for a fast, accurate temperature reading. Within about five seconds, you'll know how hot the iron is, so you can decide whether it's ready for your particular soldering material and application.

Also known as refractometers, these measure concentration with two or three drops of a solution.
