The HSC-O-HDO series horizontal drying oven dries samples evenly from 10 °C above room temperature up to 250 °C. Choose forced-air convection (101 models) for fast, uniform drying or natural convection (202 models) for gentle drying of powders, and a stainless-steel (B) or galvanised inner chamber. Four sizes run from 43 to 225 litres, with PID control, a 9,999-minute timer and an over-temperature alarm.
Why labs choose it
- RT+10 to 250 °C, ±1 °C, 0.1 °C resolution.
- Forced or natural convection: uniformity ±2.5% (101) or ±3.5% (202).
- Stainless-steel chamber option (B models).
- Smart control. Two-stage PID, touch keys, LED display, timer with timing wait and auto stop.
- Safe. Over-temperature sound-and-light alarm; parameter lock and power-off memory.
- Four sizes, up to 25 shelf positions.
