SC450G 4-laidis laidumo analizatorius
Naujo tipo SC450G 4-laidis laidumo analizatorius turi liečiamą ekraną bei yra patikimas aukštos kokybės analizės prietaisas. Be kitų pramonės šakų, dažniausiai šį modelį galime sutikti vandens valymo įrenginiuose. Jis turi 4 išėjimus, kurie gali būti užprogramuoti pagal įvairius poreikius, nuo aliarmo iki PID. Jutiklio tikrinimo funkcija yra standartiškai įtraukta į kiekvieną prietaisą. Meniu gali būti pateikiamas 8 skirtingomis kalbomis. Itin paprasto valdymo dėka, jutiklių kalibravimas atliekamas labai paprastai.

SC202 2-laidis laidumo analizatorius
SC202 analizatoriai yra skirti 2-laidėms sistemoms. Jie gali būti naudojami tiek ATEX , tiek paprastose aplinkose. Galimos kelios skirtingos komunikacijos: HART, Profibus-PA ar Fieldbus protokolai. Jutiklio tikrinimo funkcija yra standartiškai įtraukta į kiekvieną prietaisą. Be kitų pramonės šakų, dažniausiai šį modelį galime sutikti vandens valymo įrenginiuose. Pritaikomumas, maži montavimo bei priežiūros kaštai yra vieni iš šito prietaiso privalumų.
