SD Series Electrochemical Pocket Testers
SD Series Electrochemical Pocket Testers
- A handful of electrochemistry for all measuring cases
- The SD Series Pocket Testers fit comfortably in one hand and are suitable for environmental monitoring, industrial plant checks and pool use. Measure pH, redox, conductivity, salt or TDS on-site in seconds.
- Colour display for instant feedback
- A 3-colour backlit LCD provides immediate visual feedback: blue during measurement, green during calibration, and red for alarms when readings fall outside set limits.
- Designed for fieldwork
- IP67 waterproof housing, auto-hold function, stability indicator, 4 × AAA batteries for extended life (>2000 h), trouser clip and lanyard holder for mobile use.
- Easy maintenance
- Transparent lid doubles as a sample vessel for calibration or sensor storage. Simplified electrode replacement and battery change with break-proof locking mechanism.
