"We are currently using the DST400 series thermometer in a pipe thermowell to verify ice cream temperature as it is running. Knowing the temperature of the ice cream is crucial for achieving a quality product. We chose the PalmerWahl brand for its accuracy and dependability, customer service was very helpful when deciding which model would work best for us and in expediting the order. The calibrating software seemed complicated but was extremely easy to use. We are very satisfied with our purchase and I would definitely recommend PalmerWahl thermometers to anyone looking for a quality thermometer."
