Wireless Thermocouple Transmitters for Liquids and Gases
Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send real-time measurements to smartphones and tablets via Bluetooth, so you can easily confirm your processes are functioning properly. Good for route-based monitoring and preventative maintenance, they record measurements on your smart device and send alerts if equipment requires your attention. Use them to maintain a safe distance from your process or to stay out of a dirty environment. Install the app to set your parameters, choose how often you’d like to receive data, and monitor temperatures from up to 300 ft. away. Rated IP65, they’re protected against dust and washdowns.
Threaded-mount transmitters have probes to measure temperatures within pipes and tanks, producing more accurate readings than strap-mount transmitters.
Strap-mount transmitters can be installed almost anywhere with the included cable tie, so they’re good for equipment that might not have a threaded port available. However, because they mount externally, they are less accurate than threaded-mount transmitters.
Turn your transmitter into a portable monitoring system by adding a quick coupling (not included). This lets you make fast, temporary connections to various equipment in different locations.

Soldering Iron Tip Thermometers
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.
A metal alloy coating on the sensor's contact point resists corrosion and oxidation, so your readings will stay accurate throughout the life of the thermometer. And a sensor burnout alarm alerts you when the sensor is worn out and needs to be replaced.
Press the auto hold button to smooth out small, 1° to 2° fluctuations in temperature, which can be distracting when trying to read the display. Once the thermometer has a stable reading, it displays the average temperature instead of the exact temperature.
The max hold button displays the highest measured temperature, so you know your soldering iron hasn't become too hot for the job. It's especially useful when you're soldering sensitive components, such as printed writing boards (PWBs).
These thermometers have three standards markings: MET, CE, and EMC. MET means they meet U.S. and Canadian performance and safety standards. CE is the marking for European performance and safety standards. And EMC markings indicate the thermometers meet European standards for electromagnetic compatibility.
Some thermometers come with a calibration certificate traceable to NIST, which states that the thermometer has passed a test for accuracy.
