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.
