Digital is optimal: LAUDA Digital thermometers
Calibration standards are required to calibrate thermostats. All LAUDA thermostats have a device for measuring and controlling the bath temperature which, dependending on the unit range, guarantees optimal stability of the temperature measuring sequence in accordance with the latest technological standards. LAUDA thermostats are used for applications differing in their demand, yet whatever it is you wish to thermostate, the ISO 9000 standard requires the testing of the measuring instrument. The requirements made on the measuring instrument to be used for calibrating LAUDA baths should be oriented towards compliance with the bath temperature in accordance with the specific product requirements. You will check more frequently and more thoroughly a bath used for calibrating thermometers than a bath you thermostate non-critical samples in test tubes with. Alongside testing of the current value of the baths, temporal and spatial stability and precision are important. You can, for example, test how precisely the set temperature has been observed when many vessels have been positioned in the bath.
