The CAS touch! uses integrated high precision titrators, optionally with 1 or 2 titration systems (CAS-I touch! / CAS-II touch!) (Codes: 400105 / 400106), while also a version without integrated titration system is available for use with external or hand titration: CAS-E touch! (Code: 400104)

SAMPLE REQUIREMENTS:
- Min sample volume: 10 ml.
- Max sample conductivity: 11 mS/cm.
  (samples with much higher conductivity can be measured by special sample preparation).
