The Ashcroft CI Series bimetal thermometers provide reliable, tamper-proof temperature indication for industrial applications where external adjustment or pointer reset is not required. The hermetically sealed, all-welded stainless steel case prevents moisture entry, eliminating fogging, interior corrosion, and coil freeze-up.

The Maxivision® dial design places the pointer on the same plane as the graduations, enabling accurate reading from any angle without parallax error. Silicone coil dampening (rated to 400°F) provides vibration resistance and improves response time, ensuring stable performance in demanding environments.

With rear and lower connection options, the CI Series offers installation flexibility while maintaining a completely sealed, tamper-resistant construction. Heavy-duty glass lens and IP65 protection ensure durability in harsh industrial settings.

Typical applications include:

• Industrial process monitoring where tamper resistance is required
• HVAC and refrigeration systems
• Compressor and pump temperature indication
• Power generation and chemical processing
