DESCRIPTION
The LWL-DLT series of electric heating constant temperature drying oven adopts LCD multi-data operation display, with power failure memory, compensation function, and overheating alarm and prevention function. The operating temperature is room temperature +10~300 degrees Celsius, the PID temperature is accurately controlled and the temperature distribution accuracy is extremely high at +-3.0%, and T-type LCD touch screen program control can store 50 experimental programs, and single-stage temperature control and program temperature control can be mutually converted.
The volume is 30L, 45L, 65L,85L,125L, etc. to meet different needs.
FEATURES
1. High precision, high efficiency, safety and wide range.
2. Convenient operation, fixed value operation, timing operation and automatic stop.
3. Dedicated function keys realize temperature setting.
4.The auxiliary menu can realize over-rise alarm, deviation correction, and menu lock. ·
5.Insulated door technology, the outer door has low temperature and does not deform when used under high temperature conditions. ·
6.The pull-out tray partition design is convenient and quick to take and place samples.
7. L-type LCD multi-data full-screen operation display, power outage memory, power outage compensation; T-type LCD touch screen program controller, can store 50 experimental procedures, single-stage temperature control and program temperature control can be interchanged
8. The self-developed digital display over-rise preventer makes the temperature control more accurate, stable, safe and reliable.
9. overheating alarm, menu lock, overheating prevention.
