Ashcroft CI Series bimetal thermometers are tamper proof, hermetically sealed thermometers that have a Maxivision® dial to allow readability from any angle without parallax error. The connections are located on the rear and lower areas of the unit. The CI series of Ashcroft® industrial bimetal thermometers are designed for applications where external adjustment or pointer reset are not desired. The hermetic seal prevents moisture from entering the casing, thus minimizing the possibility of fogging inside the case. The Maxivision® dial provides accurate temperature readings.
