Immersion thermostats for precise temperature control
LAUDA Universa immersion thermostats are designed for precise temperature control applications and combine advanced electronics with modular system architecture, modern connectivity, and integrated safety functions.
The system is suitable for temperature control tasks up to 200 °C and offers high temperature stability together with flexible networking and circulation performance.
Technical specifications
- Working temperature range: 30 °C to 200 °C
- Temperature stability: ±0.02 K
Precise and flexible temperature control
The LAUDA Universa platform uses advanced electronics to ensure precise control accuracy. An efficient vario pump with six adjustable performance levels allows flexible flow distribution for both internal and external circulation, providing adapted volume flow and pressure.
The modular design combines an interchangeable control head with a heating/cooling base, allowing the system to be adapted to current and future laboratory requirements.
Additional process control functions include:
- Programmer functionality
- Calibration options
- Weekly scheduler for time-controlled operation
An easily accessible front switch on the control head allows pump output adjustment during operation.
Adaptive bath edge ventilation
The system includes adaptive bath edge ventilation technology (patent application) designed to:
- Prevent icing and condensation
- Stop water from entering the bath
- Block vapors to help protect the electronics
These functions are intended to increase operational safety and support longer service life.
Connectivity and remote operation
Modern communication options are integrated as standard through Ethernet and USB interfaces, with eleven optional interface modules available for additional connectivity solutions.
Integrated Wi-Fi communication allows wireless connection with:
- PCs
- Tablets
- Smartphones
The integrated web server supports remote monitoring and control within the company network using the LAUDA Command app or browser-based access. Security features include PKI protection and two-factor authentication. Connection to LAUDA.LIVE enables cloud-based data analysis and remote maintenance.
User interface and operation
A 3.5-inch colour TFT display provides:
- Progression graph display
- Menu navigation in six languages
- Readable operating status icons
Operation is performed using cursor and soft keys for intuitive control.
Integrated safety features
The LAUDA Universa immersion thermostats include a comprehensive safety concept for reliable operation and sample protection.
Safety functions include:
- Float-based low-level protection
- Adjustable overtemperature protection with acoustic alarm
- Dedicated Tmax button for direct access to overtemperature protection settings during commissioning
- Automatic limit value adjustment through smart temperature control media management
