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

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.

Thermocouple Probes with Armored
Cable for Liquids and Gases

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

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.

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.

Cut-to-Length Thermocouple
Probes for Liquids and Gases

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

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.

Threaded Thermocouple Probes with
Thermowell for Liquids and Gases

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

Remote-Mount Threaded Thermocouple
Probe Transmitters for Liquids and Gases

Remotely monitor the temperature of liquids and gases in hard-to-access, hot, and high-vibration areas.

Quick-Connect Thermocouple Probes for Surfaces

The probe tips come attached to mounting connections for fast installation.

Thermocouple Probes for Surfaces

Touch the exposed probe tip to your surface for a quick reading.

Hand-Held Thermocouple Probes for Surfaces

Often used with thermocouple thermometers, these probes have a handle for a comfortable grip.

Thermocouple Probes for Air

High-Temperature Thermocouple Probes for Air

Thick wire with ceramic insulation stands up to extreme air temperatures in forging, die casting, and heat treating.

Thermocouple Probes with Armored Cable for Air

An armored stainless steel cable protects wiring from corrosion and damage in humid conditions and harsh environments.

Heavy Duty Thermocouple Probes for Solids

The armored stainless steel cable resists wear, abrasion, and corrosion in humid and harsh conditions.

Thermocouple Probes with Armored Cable for Solids

To monitor the internal temperature of soft solids in humid conditions and harsh environments, these thermocouple probes have an armored stainless steel cable that protects wiring from corrosion and damage.

Thermocouple Probes for Solids

Pierce pliable plastics, rubber, and other soft solids to check the internal temperature.

Thermocouple Connectors

Add these connectors to thermocouple wire for easy attachment to thermometers and control panels.

Panel-Mount Thermocouple Connection Strips

Connect multiple thermocouple probes to an instrument panel.

Thermocouple Adapters

Convert round-pin male connectors to flat-pin male connectors.

Panel-Mount Thermocouple Connectors

Plug thermocouple probes into a control panel.

Threaded Thermocouple Connectors

Also known as feedthrough connectors, these mount through threaded tank openings to make connections between thermocouple probes and external equipment.

Thermocouple Signal Converters

Convert thermocouple probe signals to a 4-20 mA signal for use with switches and controllers.

Thermometers

Data-Logging Hand-Held Thermometers

Measure and store temperature readings and upload the data to a PC.

Fluke High-Accuracy Data-Logging Thermometers

Store up to 500 readings on these thermometers and determine temperature within ±0.75° F accuracy.

Fluke High-Accuracy Hand-Held Thermometers

Designed for laboratory applications, these thermometers determine temperature within ±0.75° F accuracy.

High-Temperature Panel-Mount Thermometers

Often used to remotely monitor probe readings in high-temperature applications, these thermometers have a housing designed for installation in instrument and control panels.

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.
