The Basic class is recommended for standard waterbath applications. An electronic PID process control with permanent performance adjustment and integrated self-diagnosis system ensures that the set temperature in the bath is achieved and maintained exactly.

• Temperature range: 10 °C to 95 °C plus boiling stage
• Temperature variation (time): < ±0.5 °C at 95 °C
• Double overtemperature protection: If the electronic heating control should fail, heating is switched off at a fixed level of 10 °C above the setpoint. In addition a mechanical temperature limiter, TB, switches off heating permanently if the maximum permitted bath temperature set at the factory is exceeded by 30°C, or if the fluid level is too low.
• A high-quality platinum temperature sensor Pt100 (DIN class A) in a 4-wire circuit (for stable long-term transmission of measurement signals)
• Programmable digital timer (1 min. to 99 hrs 59 min. with adjustment to the minute) for setting the Delay (delayed programme start) as well as Hold (residual operation time)
• Visual alarm if set temperature is exceeded by more than 10 °C and if heating is switched off by temperature limiter TB
