IKA ETS-D5 electronic contact thermometer with touchscreen, –20 °C to +400 °C, 0025008371

The new IKA ETS-D5 electronic contact thermometer (MPN 0025008371) completely redefines precision, safety and ease of use in laboratory thermal analysis. Developed as a high-performance mechatronic control unit for demanding laboratory processes, this instrument takes over active, direct temperature control of the medium once connected. It controls the heating power of a coupled magnetic stirrer by intelligently switching the heating plate on and off, whilst the stirrer itself acts as a redundant monitoring unit for the preset safety limits. The ETS-D5 thus transforms any compatible workstation into a future-proof, high-precision control centre for reproducible experimental series.

Integrated safety architecture for risk-free processes

From a process engineering perspective, the ETS-D5 offers a comprehensive range of sophisticated protective functions that contribute significantly to laboratory safety and risk minimisation. The system features an adjustable sensor timeout, which is triggered immediately if the probe is inadvertently outside the liquid medium. Precise temperature drop detection reacts dynamically to unexpected thermal gradients, whilst setpoint monitoring (Delta T) immediately stops temperature control if the target value is exceeded by a critical margin. To prevent operator errors in multi-user operation, the maximum settable temperature can be strictly limited via a setpoint limit. In the event of a transient fault, the heating circuit remains permanently switched off to protect personnel and the sample matrix.

Optimised PID control and application-specific modes

The instrument’s control technology ensures absolutely stable temperature control without thermal overshoot. Coupled with a high-precision, interchangeable PT1000 temperature sensor of tolerance class A, the system covers a wide operating range from –20 °C to +400 °C. Three application-specific temperature control modes ensure maximum flexibility in day-to-day laboratory work: ‘Fast’ for ultra-fast heating cycles, ‘Precise’ for working at the minimum tolerance limit, and a specialised synthesis block mode that is perfectly tailored to the thermodynamic requirements of chemical syntheses. For highly sensitive organic or biological sample structures, the heating rate can also be precisely reduced in percentage increments.

Ergonomic touch-screen control concept and documentation

The instrument’s exterior breaks away from complicated analogue designs and features a user-friendly, clear touchscreen display for intuitive parameter configuration during continuous operation. The almost completely enclosed system reliably protects the internal electronic components from aggressive vapours and liquids in the harsh everyday laboratory environment. A future-proof, integrated USB-C interface also enables the rapid, error-free export of all transient measurement data to a PC, thereby ensuring seamless documentation, validation and traceability of your processes in accordance with modern GLP standards.
