About Selecting Temperature Sensors

Extended-Life Hand-Held Thermometers
with Calibration Certificate

For a longer service life than thermocouple probes and more consistent readings over time, these thermometers have a resistance temperature detector (RTD) probe. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Data-Logging Hand-Held Thermometers

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

Extended-Life Data-Logging Thermometers

For more accurate and consistent readings than thermometers with thermocouple probes and a longer service life, this thermometer has a resistance temperature detector (RTD) probe.

Fluke High-Accuracy Data-Logging Thermometers

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

Water-Resistant Hand-Held Thermometers

A water-resistant housing and rubberized keypad stand up to washdown conditions and outdoor use.

Fluke High-Accuracy Hand-Held Thermometers

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

RTD Probes

RTD Probes for Liquids and Gases

Obtain more precise and reliable liquid and gas temperature measurements than thermocouple probes.

Threaded RTD Probes with
Thermowell for Liquids and Gases

To protect the probe from vibration, corrosion, and shock, these RTD probes come with a thermowell.

Cut-to-Length RTD Probes for Liquids and Gases

Use a pipe cutter to trim these probes for an exact fit.

RTD Probes with Armored Cable for Liquids and Gases

For long service life in harsh conditions, these RTD probes have an armored stainless steel cable to protect wiring from corrosion, abrasion, and impact.

Threaded RTD Probe Transmitters with
Digital Display for Liquids and Gases

View temperature readings and adjust settings directly on these RTD probe transmitters.

Threaded RTD Probes for Liquids and Gases

Often used to measure temperature in water lines and low-pressure steam lines, these RTDs have an NPT male probe connection for easy installation in pipes, tanks, and thermowells.

Threaded RTD Probe Transmitters
for Liquids and Gases

Send temperature readings directly to programmable logic controllers (PLCs)—with a built-in transmitter, these RTDs don’t require a separate signal converter. They’re threaded, so they’re ready to install into containers, tanks, and pipes.

Sanitary RTD Probe Transmitters with Digital Display

Check the temperature of liquids in hygienic applications such as food or pharmaceutical lines and tanks.

Thermocouple Probes

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.

Bendable Thermocouple Probes for Liquids and Gases

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

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.

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.

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 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.

Threaded Thermocouple Probes with
Thermowell for Liquids and Gases

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

Thermocouple Probes with Armored
Cable for Liquids and Gases

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

Thermocouple Probes for Liquids and Gases

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.
