Ultrastable calibration chamber Air Bath, temperature air bath

Calibration chamber - ideal for reference resistors

The air calibration chambers are designed as a convenient and cost-effective way of maintaining the temperature of reference resistors in the calibration laboratory.

Despite its space-saving design, the chamber is large enough to accommodate several resistance standards. Height-adjustable shelves allow easy positioning of the resistance standards. Even bulky reference resistors such as an ESI type SR104 can be accommodated in the air bath, as the individual shelves can be easily removed.

The cables of the resistors can be easily inserted through two insulated openings on the side or front of the device. Individual requirements for additional openings and their properties can be taken into account.

Individual developments are our specialty - describe your requirements to us and we will make you an offer!

• Ethernet and USB interfaces
• Side and front openings
• Additional shelves
• Traceable calibration certificates
• Accredited calibration certificates in accordance with ISO/IEC17025
• Transport trolleys
• Customer-specific requirements

Properties of the air calibration chambers

First-class metrological performance - stability and uniformity

The chamber is cooled and heated by a thermoelectric Peltier element with internal thermistors as sensor elements.

The Peltier element is cooled by a fan that ensures quiet operation in automatic, temperature-controlled mode. An internal fan guarantees optimum air circulation for optimum temperature stability and uniformity.

Digital or analog - controlling the calibration chamber

The most important metrics can be read off directly via a user-friendly touchscreen interface on the front of the calibration chamber. The chamber is controlled and results can also be read directly.

The "TK-Tool" software (monitoring and data acquisition software) is available for extended progress graphs and documentation. A user-friendly interface enables control and logging with external programs.

The internal temperature is shown on an LCD display on the outside of the bath. Temperature limit values can be programmed via the LCD module. If the temperature falls below or exceeds these points, the power supply to the bath is interrupted.
