Thermoelectric Coolers
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
