Fine Oven Programmable 91L Overview The Fine Oven Programmable 91L (model DH412) from Yamato Scientific is a 91-liter mechanical convection oven engineered for temperature characte ristic testing, with an operating range of ambient +15 to 360°C. LabSupplies.com, an authorized dealer, supplies this unit as a genuine Yamato Scientific product. Precise temperature stability and uniformity anchor the DH412, while an adjustable air-speed function lets technicians tune circulation to the load. An exhaust damper drives quick chamber exhaust and cooling, and dedicated exhaust and cable ports support thermocouple routing and process venting. Constructed from chrome-free electrogalvanized carbon steel with a chemical-proof baked-on exterior coating and a stainless steel interior chamber, the DH412 runs on 220V power. Built in Japan, the oven measures 49 × 33 × 43 inches and weighs 365 lbs. Manufacturing is certified to ISO 9001:2015 and ISO 14001:2015. Key Features Programmable control: enhanced program operation supports up to 99 steps, 99 patterns, and a repetitive operation function for complex multi-stage profiles. Adjustable air speed: standard-equipped airflow control tunes circulation to match the load and improve uniformity. Improved control panel: upgraded visibility and operability simplify setup, with onboard displays for power consumption, CO₂ emission, and a heat timer. Fan motor error detection: built-in monitoring flags fan motor faults to protect the chamber and the process. Exhaust damper: the damper enables rapid chamber exhaust and cooling between runs. Access ports: dedicated exhaust and cable ports route sensors and venting without compromising the seal. How to Choose the Right Fine Oven Selecting a fine oven comes down to matching chamber size, achievable temperature, control sophistication, and site power to your testing workflow. Use the criteria below to confirm the DH412 fits your application . Capacity: the 91 L chamber sets how many samples or how large a fixture you can process per run; size it to your typical batch. Temperature range: an ambient +15 to 360°C span covers most characteristic and curing tests; verify your setpoints fall inside it. Control type: programmable operation with 99 steps and 99 patterns suits multi-stage ramp-and-soak profiles rather than single fixed setpoints. Voltage: the DH412 requires 220V; confirm a matching circuit is available at the install location. Footprint and weight: at 49 × 33 × 43 inches and 365 lbs, plan bench or floor space and verify delivery access. Safety features: fan motor error detection adds protection for unattended or extended runs.
