Thermometers Direct

Thermometers Direct

We have one of the largest ranges of competitively priced thermometer ranges, these include thermometers from top brands such as ETI, Comark,  Braun, Zeal and many more.

Infrared Thermometer

Non-contact thermometer which use thermal radiation to measure the temperature of the surface it's directed to.
The non-contact option means that there is less risk involved as it allows for the operator to have some distance between themselves and the surface being assessed. These are used amongst many professions such as fire fighters seeking out hot spots in a call out, helping them identify the source of a fire incident.
Medical professions use a non-contact thermometer to measure patient's temperature when hygiene in paramount. Researchers use Infrared thermometers to monitor the temperature of a certain component when developing or monitoring manufacturing quality control situations and caterers can IR thermometers to observe food temperature.

Calibrated Thermometers

Calibrated thermometers allow you to obtain accurate temperature readings in a range of situations. Our comprehensive range of calibrated thermometers allows you to get readings that you can rely on.

To give you peace of mind in your industry’s technical tools or to meet your industry regulations, our Calibrated Fridge Thermometers can help you comply with HMRA regulations as they and the rest of our calibrated thermometers have been calibrated to the National Standards in an Independent Calibration Laboratory. Each calibrated thermometer is supplied with a calibration certification, which ensures that you’ll have written confirmation that you are receiving a reliable device.

Whether you are in the medical or catering industry or even require a calibrated for home use, here at Thermometers direct we have selected a wide variety of calibrated thermometers from leading manufacturers such as Comark and ETI in order to give you the best possible choice.

Each calibrated thermometer comes with a traced calibration certificate with at least 11 months history. If your industry requires a Full UKAS Certificate on the thermometers We now have a range of FULL UKAS Thermometers to purchase from the web site. If you have any questions about our UKAS calibration certificates or our products please get in touch and we’ll be happy to help.

Fridge and freezer Thermometers

Allow you to monitor the temperature at which you store food and medicines in order to maintain quality and comply with industry regulations.  Whether you work as part of a pharmacy, catering business, a retailer or are simply looking for freezer or fridge thermometer for home use we’ve chosen a wide range of fridge & freezer thermometers to suit your needs.

We offer a selection of both digital and analogue thermometers suitable for fridges and freezers. Our analogue fridge and freezer thermometers can be fitted and left in place; these include both dial and stick designs.

Digital Fridge & Freezer thermometer


Have a higher accuracy rate with the option of alarms to alert your attention to the incorrect storage temperature. When storing medical liquid and equipment, continuous regulation of the Fridge & Freezer temperature is essential for the nature of the products stored. You will also require a calibration certificate, which many of our thermometers can be supplied with.

Waterproof Thermometers

We have ones that fit in a pocket or larger hand held thermometers. We offer value for money thermometers at ThermometersDirect. These can be used to test running water for baths or even legionella temperature checking

Legionella Thermometer & Legionella Thermometer Kits

Here at Thermometers Direct, we understand the importance of the prevention of Legionnaire’s Disease, therefore, we have selected a large range of Legionella thermometers to help regulate water temperatures and test for risk.

Legionnaire’s disease begins to form when the storage of water is at the incorrect temperature. The bacteria associated with Legionnaire’s disease commonly forms and rapidly multiplies in temperatures between 20°C to 45°C as this is the optimum temperature for growth.

We’ve included a selection of digital waterproof thermometers, pocket thermometers and infra-red thermometers within our Legionella category to give you a precise insight of the storage of your water as well as its journey. Thermometers suitable for Legionella monitoring are available on their own and as part of legionella testing kits. If there is any trace of nutrients, in this this case rust, scale, sludge or even algae, the bacteria thrives.


Legionella thermometer/ Thermometers

You can mitigate the risk by monitoring water storage temperatures and test for hazards with our Kits
As a prevention measure we encourage the typical method of storing cold water below 20°C and hot above 60°C when stored and 50°C when distributed.   


Thermometer Accessories

Such as probe wipes, temperature log books, K-Type Probes just to name a few we also stock

We have many types of Thermometer, for many different uses a Thermometer is a Thermometer its job is to take temperature

a Thermometer does not know if its in a fridge, or a fish tank a Thermometer has lots of uses and just because it says fridge Thermometer on the Thermometer, it could be used in a room, in a fish tank it does not matter too much as long as the Thermometer is upto the task

I thought this was good until I purchased a SwitchBot bluetooth thermometer/hygrometer. The problem is that it cannot be user calibrated and you only know the absolute minimum and maximum temperatures. In reality, you need to know what is the temperature and humidity in your greenhouse hour by hour and to receive alerts to warn you to adjust ventilation. This kind of min/max thermometer was ok around 100 years ago, but for the same price you can do much better. I can check my greenhouse temperature (and humidity) from my living room armchair. Then decide if I need to pop out and open/close the ventilation or pop the shade over on hotter days. My other big problem is that the calibration is out by around 10C and cannot be adjusted. Sorry, but SwitchBot wins by a country mile.

Ordered this Thermometer to replace my previous one which I lost. (a gift to Neptune?). To take the sea temp when I swim. So far so good! and the scale is easier to read whilst treading water.
