Description

The model CTR6000 resistance thermometry bridge is a high-performance DC resistance thermometry bridge. The CTR6000 provides the latest technology in DC measurement. This way of measurement has always been a hallmark of ASL instruments and the CTR6000 continues that tradition.

The CTR6000 series features a large graphic display, combining versatility with ease of use. As well as the flexible menu options on the display, the CTR6000 also includes buttons dedicated to select common functions. For multichannel applications, the CTR6000 can be used with ASL's switch box systems CTS9000.

Data can be recorded and stored on a PC through the ULog temperature measurement and data acquisition software.

The DC version provides a switched DC sensor current to simulate the advantages of AC measurement. In addition to measuring platinum resistance thermometers (PRTs), the CTR6000 also measures NTC thermistors.
