The Ashcroft EI Series bimetal thermometers are engineered for demanding industrial applications requiring reliable, accurate temperature indication. The hermetically sealed, all-welded stainless steel case prevents moisture ingress, eliminating interior corrosion and coil freeze-up while preventing lens fogging.

The Maxivision® dial places the pointer on the same plane as the graduations, completely eliminating parallax error and allowing accurate readings from any angle. Silicone coil dampening (rated up to 400°F) provides vibration resistance and improves response time, extending instrument life in high-vibration environments.

External zero reset allows adjustment from outside the case, eliminating the need to open the thermometer for calibration. Connection options include rear, lower, and Ashcroft's Everyangle™ design for flexible installation. Available in 2", 3", and 5" dial sizes with stem lengths from 2.5" to 24".

Typical applications include:

• Industrial process piping and vessels
• HVAC systems and chillers
• Refrigeration and compressor monitoring
• Power generation and petrochemical facilities
