Quick-Connect Thermocouple Probes for Surfaces
The probe tips come attached to mounting connections for fast installation.
Note: When installing probes with wire leads, the red wire is negative.
Hose-clamp and hook-and-loop probes fit around pipes, tubes, and cylindrical containers.
Magnetic probes mount on any flat, ferrous surface.
Clip probes attach to vents, oven racks, circuit boards, and other irregular surfaces.
Bolt-on probes mount on motors, machines, and other equipment for temperature readings in high-vibration environments.
Adhesive-back probes stick to your surface and have a slim profile that fits in tight spots.
