The Ashcroft EI Series bimetal thermometers have a hermetically sealed case to prevent entry of moisture, interior corrosion, and coil freeze-up. As with other Ashcroft industrial bimetal thermometers, it has a Maxivision® dial which eliminates parallax by placing the pointer on the same plane as the graduations. The connection locations are rear, lower, and Everyangle™. The Silicone coil dampening (up to 400°F) provides vibration dampening and improves response time. The unit is made of an all-welded stainless steel construction and is IP65 protected.
