4.0 cu. ft. (113 L) holds 11 adjustable shelves (two included*)
9.5 cu. ft. (269 L) holds 12 adjustable shelves (two included*)
(*Additional shelves are sold separately)

Excellent Temperature Stability and Uniformity

High-quality construction and high-efficiency insulation provide temperature uniformity as precise as ± 0.5°C with excellent stability in the face of frequent air exchange.

Mechanical Convection for Precise Heating

Mechanical convection provides uniform heating, precise temperature control and fast drying using a blower that circulates heated air in a horizontal airflow pattern.

Precise Temperature Sensitivity

Highly responsive RTD sensor provides temperature sensitivity of ±0.1°C or better.

High efficiency insulation ensures uniformity ±0.5°C at 100°C and ±2.5°C at 300°C.

Turbo blowers for efficient drying are side mounted within the stainless steel chamber.

Conforms to Industry Standards

Complies with ASTM E145 Type IIA, ASTM D-2436, and UL 746B performance/uniformity standards.

Advanced Microprocessor PID Controls

Intuitive microprocessor PID controls deliver detailed information on current temperature set-points.

Over-Temperature Protection

Built-in 12-hour mechanical timer along with user-adjustable safety thermostat allows for power cut-out in case of over-temperature.

Energy-Efficient Design

High-limit safety with built-in circuit breaker protects the oven from power surges. A fiberglass door gasket prevents heat loss and low-density heating elements ensure long life.

Easy Cleaning

Stainless steel interior with a solid chamber floor ensures easy cleaning. All non-tip shelves can be quickly and easily dismounted for thorough cleaning.

Two Specialty Units

Model 605P: Extra baffle provides low air flow for precise drying and testing of materials with minimal disruption of volatile components.

Model 625S: Features a rear blowout panel with retaining cage and positive action front-door catches for volatile material testing.
