 USE AND FUNCTION 

NB 5, NB 9 and NB 20 Water Baths accurately control the temperatures of samples and commonly 
used  in  microbiology,  research  and  industrial  laboratories.  They  offer  excellent  temperature 
control of liquid producing a uniform and stable heating environment for the applications. They 
provide temperatures between 5°C above the ambient temperature and 99.9°C for procedures 
where  temperature  uniformity  and  stability  are  important.  The  homogeneous  temperature 
distribution in the tank is ensured by means of the heaters which are placed around chamber. 

The baths are equipped with the timer and they are controlled by a PID microprocessor controlled 
system to ensure precise temperature control. Two digital displays situated on the user-friendly 
control panel display the temperature and time values. 

Microprocessor control system will shut down the temperature sensor and in case of malfunctions 
that may occur in the control system, alarm system will be activated and the user is warned visually 
and audibly. The study data are recorded in the memory and can be transferred to external USB 
memory.  At  the  same  time,  unauthorized  persons  have  been  blocked  permission  to  change 
parameters with improved password menu. 

All  components  which  are  exposed  to  liquid  are  made  of  high  grade  stainless  steel  to  resist 
corrosion. 

The NB Series Water Baths are manufactured according to the following standards: 
EN 61010-1, EN 61326-1, EN 50419. 
This device is in compliance with WEEE Regulation. 

If the warnings mentioned in this manual are not considered, NUVE will not be responsible from 
their results.
