Contact with highly flammable liquids must be avoided. The ex-
changeable block may be hot.
The ventilation of the device must not be blocked. To ensure the
proper ventilation at all times please consider a minimum
distance of 10 centimetres on each side of the device.
Environmental conditions
The ideal area of operation of the devices is achieved at 80% relative air
humidity at most and lays b3°C - +50°C ambient air temperature.
This range should not be underrun or exceeded.
Temperature accuracy
Every HLC by DITABIS system is calibrated with a gauged high-precision tem-
perature measuring device to temperature accuracy and reproducibility. This
calibration is performed at a room temperature of +20,0°C at 10 different
temperature calibration points and oil as a reference liquid. HLC by DITABIS
reaches a very high accuracy by measuring the block temperature directly
inside the block. It can, however, not be avoided that the room temperature
affects the sample temperature in case of a large temperature difference
between room and block temperature. The anti-condensation plate reduces
this effect. We recommend using the anti-condensate plate BA 24 / BA 96 or
the tempering tub BT 01 / BT 02. When setting a process time, please note
that the sample temperature is always reached a little later than the dis-
played block temperature.
