WNB7
Water Bath WNB7

The combination of corrosion-resistant stainless steel, precise electronics and multiple temperature protection guarantees the highest level of safety in the laboratory.

 

  • Memmert Water Bath WNB7 are electrically heated, with thermostatic regulation.
  • The microprocessor temperature regulation guarantees minimum temperature fluctuations (±0.1°C), short heat-up times and lowest possible overshooting of the selected temperature.
  • The target temperature value entry is achieved digitally and can be locked against inadvertent change.
  • The actual temperature is displayed on a clear LED-display.
  • The integrated digital clock, working independently of temperature, has a runtime of 1 minute to 99,95 hours.
  • All values are shown on the LED-display.
  • The self-diagnostic system integrated with the regulator enables quick troubleshooting in the case of errors.
  • Very easy cleaning.
  • Completely made of stainless steel.

Safety

Temperature control mechanical temperature limiter TB protection class 1 switching the heating off at approx. 30°C above max. the temperature of the bath
Temperature control in case of overtemperature due to failure, the heating is switched off at approx. 10°C above the set temperature (fixed value)
Autodiagnostic system microprocessor PID-temperature controller with integrated auto diagnostic system with fault indicator

Heating concept
