Model 3603-A, 3604-A, and 3605-A Thermo Units
Features
• High temperature (3604-A: 100 to 1,200°F), low temperature (3605-A: -40 to 250°F) and compact (3603-A: 100 to 600°F) models available.

• Unique dry well design and precision adapter chucks eliminate the need for messy thermal transfer oils.

• Excellent accuracy and temperature stability.

• Microprocessor control for safety and ease of use.

• 3604-A and 3605-A incorporate an IEEE-488/GPIB interface, enabling remote control and automation using a PC compatible computer.

• Rugged aluminum cases protect the units from harsh environmental conditions and include storage for adapters and accessories.

• Designed for simple field service and maintenance.

• 3604-A and 3605-A capable of automated standardization and calibration using KNC Model 3724 Automatic Thermo Unit Calibration Kit-saves time and effort.

• All models conform to rigorous U.S. Military specifications.

• Wide range of standard inch size and U.S. Military Specification adapter chucks available-contact KNC for custom adapter chuck sizes.
