Features
The TB30 is a thermostatic bath with 30 litre bath contents. The bath fluid is heated via a micro-processor controlled heating element which guarantees precise temperature control. When working at ambient temperature, a cooling coil offers stable temperature when connected to a chiller or tap water.
Circulated fluid will lower the bath temperature thus enabling stable temperature control. The bath is equipped with fluid level detection and a levelling platform which can be easily adjusted.
The bath temperature can be set to a maximum of +120°C (248°F) in steps of 0.01 degree. The temperature reqadout is menu selectable between °C or °F. The overall system accuracy is 0.02°K.
The bath uses a vane to stir the bath liquid. A special baffle plate ensures maximum homogeneity.
The insulation of the bath and electronic design result in a stable working temperature of ± 0.02°. The display has a resolution of 0.01°C.
The bath conforms to CE regulation. It further is equipped with a mechanical and resettable safety thermostat.
