Your new favourite food thermometer
The Checktemp4® features a foldaway probe which is safely housed within the thermometer body when not in use and automatically switches on the thermometer when unfolded, making it effortless to quickly measure the temperature of your food.
Hanna CAL Check technology ensures the thermometer circuit is checked for accuracy every time the thermometer is turned on, displaying the result on the large digital display and giving peace of mind that readings are accurate and true. Peace of mind in one, small package.
Any temperature, any time
With a wide temperature range of -50 to +300 and a 0.1 resolution, the Hanna Checktemp®4 offers the best accuracy of any folding probe thermometer across the critical food temperature range, providing results to an amazing accuracy of +/-0.2C. You can choose to configure your Checktemp®4 to display in Fahrenheit, if you prefer, and will then be provided with a range of -58 to +572F with an accuracy of +/-0.8F across the critical food temperature range.
Battery life? No problem
To save battery life, Checktemp®4 will automatically power off and enter a sleep mode after a timed interval which is uniquely user configurable from 1 min, 2 mins (default), 8 mins, 60 mins, or you can even disable this feature if you prefer. Only the Hanna Checktemp®4 offers you the choice! A built in motion sensor automatically ‘wakes’ the meter and switches it on as soon as you next pick it up, so it’s always ready to take your next food temperature.
No need to worry about slips, trips and spills
Unlike some folding probe thermometers which are splashproof to IP66, the Checktemp®4 is fully waterproof to IP67, which means it can be washed under the tap or even immersed in liquid, and just in case you accidentally drop it in the washing up bowl - it even floats to aid retrieval.
Additionally, the Checktemp®4 features unique silicon grips on both the front and the back of the thermometer casing to make it much easier to hold, less likely to drop, and to facilitate a secure ‘hold’ when put down on slippery surfaces, such as wet or greasy stainless steel kitchens, as found in professional kitchen preparation areas.
The technical details
Every Checktemp®4 is supplied complete with batteries which offer a minimum life expectancy of 4000 hours. A low battery icon in the thermometer display will alert you, and give you plenty of notice, when the batteries need replacing and we’ve designed the Checktemp®4 so that you don’t need to find a screwdriver to open the battery compartment, as we understand how frustrating it is to have to find one, especially in a busy kitchen.
A fast response Ø3 x 103mm food grade stainless steel probe is neatly folded back into the body of the Checktemp®4 when not in use, making it easy to carry in a pocket and ready for use as soon as the probe is unfolded. Checktemp®4 is one of the fastest folding food thermometers you can buy with temperature response times as fast as 3 seconds.
Easy compliance with HACCP
Choose from 6 colours in our Checktemp4® range, reflecting the HACCP regulations to keep food types separate and your kitchen clean, hygienic and safe. Whichever colour you choose, all Checktemp®4 thermometers can be used for all types of food and at all temperatures, with the versatility you need to safely prepare, cook and serve delicious dishes.
Don't need to comply with HACCP? You can use any colour Checktemp®4 for any food temperature you like. If you’re buying for home and want an all-purpose food thermometer that offers professional-grade accuracy, then choose the colour you prefer and make sure you clean the probe between measurements. Easy.
