Product Description
The Yamato DX-312C is a 28 L natural convection constant temperature drying oven for routine laboratory drying, curing, sterilizing and heat testing. Gravity air circulation moves heat without a fan, so lightweight samples, powders and filter media are not disturbed during the cycle.
Operation is deliberately simple: a digital PID controller with ▲▼ key entry, four operating modes and a calibration offset that lets you align the display to your own reference thermometer without a service call.
Key Features
- Natural convection heating — no fan turbulence over the sample
- Digital PID control with ±1 °C control accuracy
- Four operating modes: fixed temperature, auto start, auto stop and quick auto stop
- Calibration offset function for alignment to a reference standard
- Stainless steel interior with 6 steps of shelf positions
- Power failure compensation and key lock
