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

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.

Thermocouple Probes for Liquids and Gases

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
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.

Cut-to-Length Thermocouple
Probes for Liquids and Gases

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

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 Probes with Armored
Cable for Liquids and Gases

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

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.

Thermocouple Probes for Surfaces

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

Quick-Connect Thermocouple Probes for Surfaces

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

Noncontact Infrared Thermocouple Probes for Surfaces

Monitor the temperature of hazardous, sensitive, and hard-to-reach surfaces without touching them.

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.

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.

Terminal Blocks for Thermocouple Wire

Connect thermocouples to extension wire or instrumentation.

Thermocouple Signal Converters

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

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.

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.

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.

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.

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.

Pipe-Mount Hazardous Location Thermometers

Mount this thermometer on pipes in environments with flammable gases, combustible dust, and ignitable fibers.

RTD Transmitters

Send temperature readings from RTD probes in containers, tanks, and pipes to switches and programmable logic controllers (PLCs).

Temperature and Humidity Chart Recorders

Temperature and Humidity Chart
Recorders with Calibration Certificate

Track ambient temperature and humidity over time with this recorder that includes a calibration certificate traceable to NIST that states it has passed a test for accuracy.

Remote-Reading Temperature Chart Recorders

Record temperature in hard-to-access areas. This recorder has a remote probe on a 15-ft. cable.

Remote-Reading Temperature, Humidity, and
Dew Point Chart Recorders with High/Low Alarm

Remotely record temperature, humidity, and dew point up to 10 feet from the display and set the alarm to sound and flash the display if temperature readings rise above or fall below a set range.

Charts for Temperature and Humidity Chart Recorders

Place these charts in temperature and humidity chart recorders to document readings over a period of time.

Remote-Reading Temperature Chart
Recorders with High/Low Alarm

To alert you of temperature fluctuations, this recorder sounds an alarm and flashes the display when temperature rises above or falls below the programmable temperature range. It has a probe on a 4-ft. cable for taking readings in hard-to-access areas.

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.
