DescriptionThis handy little Pocket Thermometer is great for spot checking temperatures accurately and quickly. The clear easy-to-read dial with pointer directly driven by the precision sensitive bi-metal helix coil gives an accurate reading every time. With head and stem of stainless steel and plastic crystal and no mercury or glass, this thermometer is virtually unbreakable. The pocket case is constructed of plastic which allows it to be securely fastened to the pocket, preventing loss, yet keeping it easily accessible. Should the need ever arise for resetting the pointer, an external adjustment feature permits simple zero reset in seconds.
