Abstract

Keksinnön suoritusmuotojen kuvaus koskee sylinterimäisellä mittapäällä varustettua prosessirefraktometriä, käsittäen mitattavaan prosessinesteeseen sijoitettavan, tiiviisti mittapäähän sopivan prisman (500), jossa (500) on myös kaksi sen (500) vastakkaisille puolille hiottua kiillotettua tasopintaa (501), toimiakseen refraktometrin peileinä. Prisman (500) pääty on prosessoitu kulmikkaaksi pinnaksi, jolla on sylinterin kanssa yhteinen akseli, aikaansaaden kulmallisen sulkupinnan (501b) prisman pinnan ympärille mitattavaa nestettä (502) vastaan. Keksinnön erään suoritusmuodon mukaisessa sylinterimäisellä mittapäällä varustetussa refraktometrissä (REF) on lisäksi mittapään kärkiosaan (502) sisäänrakennettu lämpötila-anturi (510). Keksinnön erään suoritusmuodon mukaisen mainitun prosessirefraktometrin (REF) mittapää on sovitettavissa läpimitaltaan 12 mm tai ½” prosessiliityntään.
