Honeywell 113228 Purple Peeper Phototube  
Written by AnubisTTP on 2007-04-11  

Description

This long narrow device is a special type of phototube, designed to detect UV light. Unlike most phototubes which have an argon fill, this tube is filled with neon, which can be seen through the tube's clear tip if the tube is ionized. The 113228 is used almost exclusively in Honeywell Purple Peeper and Mini Peeper industrial flame sensors. It can be difficult to find sockets for the small three-pin base.
