"Temp'n'Glow",thenewsecretamongnixie

enthusiasts,isaNixietubethermometerfortheslim,beautifulIN‐16tubes.



Fast,secureinstallationwithoutanyadjustmentarethefeaturesofthiskitas

wellasitsmodernlook.



Butthetechnologyisstateoftheart,too.

Asmartmenusystemmakesoperationeasy.

Adjustablechangeinterval,errordetectionandmanyotherfeaturesarestandardon

"Temp'n'Glow".



Ahigh togo

lightistheso‐called"CathodePoisoningPrevention".Thisfeatureallowsthedigits

throughcertainperiods(slot‐machineeffect).

Thiswillprotectthecathodedepositsandasaresultofthatyourtubeslivelonger.

7 Special Notes on the IN-16 tubes

ThereareseveralvariantsoftheIN‐16tubes.OnehasaholewithØ4mminthespacer,theotherhasnot.

Hereyoucanseethisdifference:



Withhole:withouthole

 



fyoufitanyunderbodylightingtubes,thisdifferenceisnotimportanttoyou.However,ifyouinstallan

underbodylighting,youhavetorefertothefollowing.



Ifyouusetheversionwithaholeinthespacer,thereisnoneedtochangeanything,becausetheLED

exactlyfitsintothishole.

Butifyouusetheversionwithoutthehole,thenyouhavetodrillaholeofØ4,5mmintothemiddleofthe

spacer.Todoso,slideawaythespacerfromthetubeanddrillthehole.
