DH300 is microprocessor controlled dry bath incubator. Instead of traditional water bath device, the heat-conducting medium is high purity alumium. The exact desired temperature is easily set using the arrow keys on the sloped control panel while values are shown on the large digital display. No checking of a thermometer and readjusting temperature is necessary. The user calibration feature allows for easy calibration to in house standards when required. This product can be widely used in preservation and reaction of samples, DNA amplification, electrophoresis denaturation and serum solidification, etc. Features:  LCD displays.  Automatic fault detection and buzzer alarm function  Temperature calibration function.  Easy replacement and cleaning of block.  Built-in over temperature protection.  Optional power automatical recover and boot automatically run function.  Multiple safety protection .Safe and reliable with CE standard.  Customed blocks are accepted.  12-month warranty.
