Forced air incubator drying oven TR series

laboratoryfor sample storagefor general purposes

Overview
Electric drying ovens of the TR series provide uniform forced-air heating up to a maximum working temperature of 300 °C. Suitable for drying, sterilizing and warm storage; standard models available from stock with short delivery times.

Product details
Horizontal forced-air circulation ensures high temperature uniformity. Robust stainless steel chamber and housing combine corrosion resistance and ease of cleaning. PID microprocessor control with integrated self-diagnosis and data-logging options support process control and documentation.
