Product Description
The Yamato DR-201-115V is a high temperature natural convection oven with a control range of 300 to 700 °C. That upper limit is what makes it a different instrument from a drying oven: at 700 °C you are doing ashing, binder burnout, heat treatment of small metal parts and ceramics work, not drying glassware.
It sits in the gap between a 260 °C laboratory oven and a muffle furnace — a chamber you can programme over 30 steps, with a stainless interior rather than refractory brick, in a 520 mm wide benchtop cabinet.
Key Features
- 300 to 700 °C control range, ±5 °C at 700 °C
- Reaches 700 °C in about 70 minutes
- 6 programme patterns with step weight, repeat, hold and skip
- Ceramic fibre and rock wool insulation
- Stainless steel chamber, 13.75 L
- Double K thermocouple
- Calibration offset, keypad lock and auto resume after power failure
