We are currently selling a Marine Blue colour Thermapen Classic thermometer at a very special price. This offer is only available on this website while stocks last - so get yours today!

The Thermapen Classic is fully configurable using switches in the battery compartment. Here you can choose to disable auto-off mode, choose  °C or °F scales and select 1° or 0.1° resolution.

The Thermapen® Classic is the best instant read digital thermometer you can buy. The Thermapen® Classic is used by many of the top restaurants and best known chefs worldwide. 

What it does?

The Thermapen® Classic is ideal for taking temperatures of cooked, re-heated and chilled foods such as meat joints, fish, soups, stews and pies. It incorporates a clear, easy to read display, with a precise read-out of temperature over the range of -49.9 to 299.9°C (-58.0 to 572.0°F).

Great looks. And brains, too.

The Thermapen Classic thermometer incorporates a reduced tip, stainless steel, food penetration probe that conveniently folds back through 180 degrees into the side of the instrument when not in use. The response time of any thermometer is dependant on many factors, the mass of the sensing tip, heat transfer and, most importantly, the state of the substance being measured. With both air and liquid, agitation is crucial to rapid response. The ETI calibration laboratory has tested the Thermapen® in a stirred water bath with amazing results. Each Thermapen® 3 reached 100% of the test temperature in an astonishing 3 seconds. The Thermapen 3 is available in a range of vibrant colours, so you can buy one to match your taste.


The casing is manufactured from a new washable "Biomaster" material that reduces bacteria growth and the egonomic rubber seal reduces the risk of the ingress of water or dust. As well as being water resistant, it is still 'probably' the fastest reading contact thermometer on the market today. The true temperature of a product can be tested in just three seconds.


What is Biomaster?
Biomaster additives are powerful broad-spectrum inorganic, silver-based biocides for use in plastics, helping to reduce hygiene risks. The concentration of silver, in the patented anti-microbial active agent in Biomaster, provides a release of silver ions on demand, which in turn safely inhibits microbial growth.


Why use a Thermapen® Classic.

Biomaster protection

Biomaster antimicrobial technology is incorporated into every Thermapen product during the manufacturing process, ensuring lifelong protection against the risk of bacterial cross contamination. As well as being harmful to health, outbreaks of food poisoning can damage brands, and the reputation of stores, food producers and restaurants.

The risk of food-borne contamination is widespread, existing in restaurants, bars, hotels, supermarkets, hospitals, schools, aircraft, cruise ships and your home. Anywhere where food is made, prepared or eaten.

Biomaster treated products have been proven to reduce the growth of food borne bacteria such as E.Coli, Salmonella and Campylobacter by up to 99.99%, so by choosing a Thermapen with Biomaster additive, you are protected 24 hours a day, every day.

What is Biomaster?

Biomaster Antimicrobial Technology is the leading range of safe, effective and permanent additives for the control of harmful bacteria, making any surface cleaner and more hygienic for its entire lifetime.

Proven to quickly reduce bacteria by up to 99.99% Biomaster is an effective means of reducing the growth of MRSA, E.Coli, Salmonella Campylobacter, Legionella and over 50 other species.

Incorporated into the body material of your Thermapen, Biomaster becomes an integral part of it, providing durable, lifelong protection against the threat of cross contamination. 

How does it work?

The active ingredient in Biomaster is silver. Silver has been used in its pure form for many centuries to prevent the growth of bacteria.

Incredibly durable, long lasting and highly active, when Biomaster is added during manufacture it is dispersed throughout the product casing, will not wash off and will last for its entire lifetime. Biomaster provides antimicrobial protection without allowing bacteria to develop resistance.


Biomaster has 3 different modes of action:




The Biomaster 3 stage mode of action does not allow bacteria cells to develop resistance, making Biomaster future proof and highly resistant against antibiotic resistant species such as MRSA.
