High Performance Thermoelectric Coolers C4877, C4878 Series

The C4877 series and C4878 series are thermoelectric coolers constructed

with enhanced electrostatic and magnetic shielding (C4877 Series). This

minimizes the influence of external noise on the photomultiplier tube and

thus significantly improves photometric accuracy. These coolers offer user-

friendly functions such as easy temperature control and pilot lamp blank-

ing. The C4877 series is designed for use with 51 mm (2") or 38 mm

(1-1/2") diameter head-on photomultiplier tubes, and the C4878 series for
