Apparently simple, the NB series of unstirred water baths is nevertheless controlled by a PID microprocessor system giving excellent temperature precision, assisted by the triple insulation, for this class of instrument. A timer enables set protocols to be observed. Most of the footprint of the water bath is usable to accept samples, since there is no pump, circulator or heater inside the chamber. A convenient drain permits fast discharge of the water. Their large displays are easily visible from across the laboratory. Designed for many general and special applications in microbiology, research and industrial laboratories. Three different useful volumes: 4, 7 and 15 liters Temperature range: Ambient Temperature +5°C / 99.9°C Excellent temperature control of liquid by programmable PID microprocessor control system Highly visible dual display for temperature and time Delayed start timer Seamless stainless steel tank for easy cleaning Excellent temperature uniformity and stability by triple insulation Footprint almost equal to the working area to save bench space
