The Super-Fast Thermapen has become a favourite among restaurants, gourmet chef's / cooks and food quality managers worldwide. Literally thousands are in use everyday around the world. The clever foldaway probe and the simple pocket design replaces the more costly and bulky handheld thermometers and probes while using the same professional thermocouple technology. This new generation Thermapen features a robust, splash-proof design with waterproof seals to protect the thermometer from wet hands and kitchen mishaps. The SuperFast Thermapen thermometer incorporates the "Biomaster" additive that reduces bacteria growth and the ergonomic rubber seal reduces the risk of the ingress of water, dust or food. As well as being water resistant, it is still 'probably' the fastest reading contact thermometer on the market today. The SuperFast Thermapen 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. Numerous test kitchens and professional chef's have tested the Superfast Thermapen with amazing results - the SuperFast thermometer reaches 100% of the test temperature in under four seconds. The SuperFast Thermapen incorporates a larger digital display with a precise read-out of temperature over the range of -49.9 to 299.9ÃÂ°C with a 0.1ÃÂ°C resolution and an accuracy of ÃÂ±0.4ÃÂ°C over the range of -49.9 to 199.9ÃÂ°C, thereafter ÃÂ±1ÃÂ°C. Both low battery (icon) and open circuit indication are also displayed, when applicable. Each Thermapen is powered by two lithium coin cell batteries (supplied) with a minimum life expectancy of 1,500 hours.
