Thermocouple Probes with Armored Cable for Air

An armored stainless steel cable protects wiring from corrosion and damage in humid conditions and harsh environments. The bayonet mounting connection securely holds the probe in place in high-vibration environments, and the included mounting adapter converts the bayonet connection to a threaded connection.
Note: When installing probes with wire leads, the red wire is negative.

Wireless Thermocouple Transmitters


Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send data 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'll send alerts if equipment requires your attention. 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.
