The Lindberg/Blue M HTF55122A is a single-zone, split-hinge tube furnace for laboratory and industrial heating applications requiring precise temperature control and uniform heat distribution. Operating from 100°C to 1200°C (2192°F), this furnace accommodates 0.75-inch to 1-inch diameter process tubes in either horizontal or vertical orientation. The patented Moldatherm LGO heating element modules deliver superior radial and linear temperature uniformity with rapid heat-up and cool-down cycles, while minimizing maintenance demands through long-life, energy-efficient design.
The furnace features a compact cabinet with high-temperature resistant paint and a heat-reflecting element support assembly that creates effective insulating air spaces, reducing exterior surface temperature. A long-life Platinel II thermocouple with 10ft compensated lead wire and polarized plug enables reliable temperature sensing. Temperature control is achieved through an independent digital control console (ordered separately), featuring microprocessor-based PID control with single-segment, single-setpoint ramp capability. The control system displays actual temperature versus setpoint simultaneously in °C or °F, includes built-in adjustable high-limit overtemperature protection, and offers optional RS485 digital communications.
