Pond Engineering’s K44L Furnace provides an affordable, compact system for comparison calibration of up to six thermometers from 90°C to 450°C. The innovative three-zone furnace offers the user-active control of the primary setpoint as well as the temperature gradient between the core and each of the guard blocks.

Core and guard-zone blocks of machined aluminum suspended in a fiberglass insulated envelope provide excellent responsiveness, while simultaneously requiring minimal power to achieve the desired setpoint. This configuration also provides excellent axial and circumferential gradient control while maintaining a wide setpoint operating range. Custom configurations with even higher upper operating temperature limits are available upon request. Rapid heating and stabilization times coupled with integrated user prompts and configuration functions make calibrations quick and simple.

Interactive controls on a sloping front panel increase usability in a stand-alone configuration. Optional remote interface (RS-232 or USB) allows users to integrate the K44L into an automated calibration system. Communication software is available for either interface, and allows users to monitor and configure the system from any remote computer with a graphical interface.
