VIKING-EC250 laboratorijski konduktometar (Ekran na dodir, klasa 0.5)
VIKING-EC250 je profesionalni laboratorijski konduktometar s ekranom osjetljivim na dodir za rutinsku i naprednu analizu vode.
Mjeri provodljivost, otpornost, TDS, salinitet i temperaturu,
podržava nadzor ultračiste vode i određivanje conductivity ash.
5.0” kolor ekran na dodir, tačnost klase 0.5 i elektroda sa 4 prstena osiguravaju stabilne rezultate od vrlo niskih do hiperslanih uzoraka.
Ključne funkcije
- 5.0” kolor ekran na dodir za brzo i intuitivno upravljanje
- Tačnost klase 0.5 (bolja od uobičajene 1.0 klase)
- 4-prstenasta elektroda minimizira polarizaciju u rastvorima visoke provodljivosti
- 10 ugrađenih međunarodnih standardnih rastvora; podržani korisnički standardi
- 3 režima kompenzacije temperature (linearno / nelinearno / isključeno)
- 3 režima završetka mjerenja (auto / ručno / tajmer)
- GLP baza: 1000 mjerenja, revizibilno i pratljivo
- USB i RS232 izlaz; opcioni štampač

What’s Different? (Delta)
| Category | VIKING-EC240 SKU:PRO5360 | VIKING-EC250 SKU:PRO5361 | Comment |
|---|---|---|---|
| Measurement Modes | No Ash | Includes Ash + built-in sugar-industry method | Choose T503F if you need conductivity-based ash. |
| GLP Database | 1000 records | 2000 records | Double capacity. |
| Temp. Compensation | Linear / Non-linear / Off | + Pure-water | Handy for ultra-pure water workflows. |
| Ash Specs | — | Range: 0.000 – 2.000 %*; Res: Auto 0.001–1; Acc: ±0.5% | Likely a typo—practically ash % ≤ 100 %. |
Conclusion & Recommendation
- VIKING-EC240 / — Best choice if you do not need Ash determination. Same core performance, 1000-record GLP database, lower cost likely.
- VIKING-EC250 — Choose this if you need Ash (e.g., sugar industry conductivity-ash), work with ultra-pure water (extra “Pure-water” compensation), or want a larger 2000-record GLP database.
