Free 303-159 fast response probe included with purchase!

Designed for the busiest food service kitchens, our new Therma Plus is a must have food safety tool. It’s rugged, waterproof, accurate, and easy to use.

With a case rating of IP66/67, this new thermometer won’t fail you if your staff drops it on the floor or in the sink. It’s waterproof and built from extruded aluminum with protruding rubber seals for impact resistance. And, there are only two buttons to press. All you need to know is how to turn it on and hold the current reading so you can write it down.

What about performance? The Therma Plus displays temperature on its big digit display with a meter accuracy of ±0.5°F from 32°F to 212°F. Each one is individually calibrated in an accredited lab and ships to you with a NIST-Traceable calibration report.

Each Therma Plus includes a Type K Thermocouple socket for connecting a huge variety of probes to match your exacting application. Choose a surface probe, general immersion probe for liquids, a penetration probe for frozen foods or meats, or a high temperature wire probe for smokers or ovens. Whatever the need we’ll find a probe that will work!

Suggested Type K Probes:



Plug-Mounted Fast Response Penetration Probe
This plug mounted fast response probe is designed for measuring temperature very quickly. This is the same probe as we use on the Super-Fast Thermapen and Fast Response Penetration Probe. Max temp: 482°F (250°C).
To Order
113-159 Plug-Mounted Fast Response Penetration Probe

 




Fast Response Meat Probe
Originally designed for measuring burgers, steaks and thin meat portions, this probe is often chosen for other purposes because it’s diameter is smaller than our handheld needle probe and it’s a bit quicker while leaving an even smaller hole. The 3.35" length allows you to reach the center of even a large burger when entering from the side, or it will reach the center of roasts for an extremely fast measurement. An optional detachable coiled or straight extension lead is also available. Max temp: 482°F (250°C).
To Order
113-151 Fast Response Meat Needle Probe

 



Miniature Needle Probe
Use this probe for very small samples or just speedy response times. The PTFE cable and sealed junction allow the use of this probe in ovens or other cooking processes. Readings take only 2-3 seconds to a full value. Max temp: 482°F (250°C).
To Order
THS-113-181 Miniature Needle Probe, 39" cable

 


Plug-Mounted Penetration Probe
Sharp penetration probe is mounted directly to an industry-standard miniature thermocouple plug. No cable included. Plug this probe directly into most thermocouple meters for a one-handed thermometer (meter/probe combination). Probe tip is swaged to a smaller diameter then sharpened for fast measurements and easy penetration. An optional detachable coiled or straight extension lead is also available. Max temp: 482°F (250°C).
To Order
113-161 Plug-Mounted Penetration Probe 5"
113-167 Plug-Mounted Penetration Probe 9"

 


Plug-Mounted Surface Probe
Features a 0.32" diameter cylindrical head with a stainless steel ribbon. The thermocouple sensor is welded to the back of the ribbon. Max. temp. 482°F
To Order
113-045 Plug-Mounted Surface Probe - Straight

 


Plug-Mounted Mineral Insulated Probe
Flexible, high temperature, stainless steel, rounded tip mineral insulated probe. Ideal for measuring high temperature liquids. Maximum tip temperature 2012°F.
To Order
113-213 Plug-Mounted High Temperature Mineral Insulated Probe

 


Plug-Mounted Air/Gas Probe
The stainless steel shaft is open ended with ventilation holes provided in the sides to expose the bare thermocouple sensor to the outside for faster measurements of air or gases. Ideal for environmental readings, cold storage or HVAC work. Max. temp. 482°F.
To Order
113-301 Plug-Mounted Air/Gas Probe

 


High Temp Alligator Clip Oven Probe
Stainless steel overbraid protects this probe along with a fiberglass inner sheath. An alligator clip allows you to place it right where you need it. 120" lead. Max temp: 950°F (510°C).
To Order
8468-22 High Temp Alligator Clip Oven Probe

 


High Temp Wire Probe
Fibreglass insulation with exposed junction. Use for ovens and appliance temps. Max. Temp 662°F
To Order
113-382 39" length
113-383 78" length
113-385 10' length

 



Fast Response Penetration Probe
We start with an 1/8" shaft and reduce the diameter to 1/16" at 1 inch from the needle tip. This gives you a compromise between durability and the better speed of a needle type probe. Used in liquids and soft semi-solids including rubber, plastics and similar materials. A complete reading takes only 4 or 5 seconds. Max temp: 482°F (250°C).
To Order
303-159 Fast Response Penetration, coiled cable

Right Angled Precision Surface Probe
This is the fastest and most accurate handheld surface probe we’ve seen. Readings generally take less than 5 seconds! The sensor is made from flat-spring ribbons of thermocouple material. Very popular in equipment servicing applications and in the plastics and packaging industries. The shaft has a right angle bend to improve access where the surface is hard to reach. Max. temp. 932°F
To Order
303-032 Right Angled Precision Surface Probe, coiled cable

 



Griddle Probe
Heavy duty weighted surface probe for measuring temperatures of hot plates and grills. Stainless steel armor protects the cable from hot surfaces. Uses the flat ribbon spring sensor design for speed and accuracy. Though designed for the fast food business, this probe is used by many other industries where it would be convenient to set the probe on a surface and leave it for extended measurements. Max. temp. 482°F
