Benefits at a Glance
·         Patented safety multi-function head for simultaneous positioning
·         Draining system
·         Thermal protection shield
·         5-test station metal heating block
·         Air and steam flow calibration sets (optional).


Convenient Operation
·         The multi-function head was designed for the safe and simultaneous positioning of all 5 pre-adjusted inlet tubes. No manual handling and assembling of the hot conical jet tubes is required. After one turn only, all tubes are in their resting, pre-heating or working position. The position of the handle assures that neither steam nor hot air is hazardous to the operator.
·         Safe withdrawal of condensed water from sample beakers and the compensation of uncontrolled steam eruptions is assured by an efficient draining system.
Over-temperature protection cut-off.
