About Selecting Temperature Sensors

Bendable Thermocouple
Probes for Liquids and Gases

Bend these probes up to 90° for a custom fit.

Thermocouple Probes for Liquids and Gases

Thermocouple Probes with Armored
Cable for Liquids and Gases

Protect thermocouple wiring from wear and corrosion with an armored stainless steel cable.

Cut-to-Length Thermocouple
Probes for Liquids and Gases

Trim these probes to the exact length you need with a pipe cutter.

Threaded Thermocouple
Probes for Liquids and Gases

For easy installation in thermowells, tanks, pipes, and other closed vessels, these thermocouples have an NPT male probe connection.

Threaded Thermocouple Probes with
Thermowell for Liquids and Gases

The included thermowell protects the probe from vibration, corrosion, and shock in tanks and pipelines.

Heavy Duty Threaded Thermocouple
Probes for Liquids and Gases

To withstand harsh environments, a protective head seals out dust and moisture and thick probe walls reduce wear on the sensing element.

Thermocouple Probe Transmitters

Threaded Thermocouple Probe Transmitters
with Thermowell for Liquids and Gases

Measure the temperature of liquids and gases without damaging the probe on these transmitters. An included thermowell shields the probe from vibration, corrosion, and shocks in tanks and pipes.

Hazardous Location Threaded Thermocouple
Probe Transmitters for Liquids and Gases

Safely measure the temperature of liquids and gases wherever flammable gases, dust, and fibers are present.

Wireless Thermocouple
Transmitters for Liquids and Gases

Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send real-time 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.

Threaded Thermocouple Probe
Transmitters for Liquids and Gases

Send temperature readings from tanks, containers, and pipes to devices such as remote displays and programmable logic controllers (PLCs) without the need for a separate thermocouple transmitter.

Thermometers

High-Temperature Hand-Held
Thermometers with Calibration Certificate

These thermometers have a thermocouple probe that can handle extreme temperatures, and come with a calibration certificate traceable to NIST that states they have passed a test for accuracy.

High-Temperature Water-Resistant
Hand-Held Thermometers

The thermocouple probe measures temperatures up to 500° F, and the thermometer housing meets IPX7 for protection from temporary submersion.

Food and Beverage Hand-Held Thermometers

For use in food-processing applications, this thermometer meets NSF/ANSI standards and includes a thermocouple probe with a pointed tip to pierce dense meats and frozen foods.

Remote-Reading Magnetic-Back Thermometers

Remotely check temperature on the go. These thermometers have a magnetic-back display for temporary mounting and a thermocouple probe with a 5-ft. coiled cable.
