Solids Gauges | McMaster-Carr

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.

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.

Thermocouple Probe Transmitters

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. These transmitters convert readings to analog signals and send them to devices such as remote displays and programmable logic controllers (PLCs).

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. Made of either stainless steel or nickel, the probe resists corroding in liquids and gases.

Thermocouple Probes

Thermocouple Probes with Armored
Cable for Liquids and Gases

To prevent wear and corrosion, an armored stainless steel cable protects the wiring that connects these probes to your temperature-monitoring device. The probes themselves are also made of stainless steel, so you don't have to worry about corrosion when you're measuring the temperature of liquids and gases.

Thermocouple Probes for Liquids and Gases

Made of stainless steel, these probes measure the temperature of liquids and gases without corroding.

Reduced-Tip Thermocouple
Probes for Liquids and Gases

Get the fast response times of a small-diameter probe without sacrificing durability. The thin tip reacts quickly to temperature changes while the rest of the probe is thick for strength.

Dual-Output Thermocouple
Probes for Liquids and Gases

Send temperature readings to two separate devices—these probes, also known as duplex thermocouples, have two thermocouples inside.

Noninsulated Thermocouple
Probes for Liquids and Gases

An economical alternative to insulated thermocouple probes, these probes measure the temperature of liquids and gases.

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 probes have a male NPT fitting.

Hazardous Location Threaded
Thermocouple Probes for Liquids and Gases

Safe to use while measuring temperatures near flammable gases or combustible dust, these probes have an explosion-proof head that’s FM approved.

Thermocouple Probes with Armored Cable for Solids

To shield the wiring from corrosion and wear in harsh environments, these probes have an armored stainless steel cable. Use their narrow tip to pierce pliable plastic, rubber, and other soft solids to check the internal temperature.

Thermocouple Probes for Solids

Pierce pliable plastics, rubber, and other soft solids to check the internal temperature. Also known as penetration probes, these thermocouple probes have a stainless-steel housing with a narrow tip.
