Water Quality Analyser
LS-PE138, Microprocessor based Multi Parameter Water Quality Analyser. Measures directly pH, EMF, Temperature, Electrolyte Conductivity (EC), Total Dissolved Solids (TDS), Dissolve Oxygen (DO) & Salinity, Colorimetric, Abs./%T and Turbidity in Water Sample one at a time.
SALIENT FEATURES
- Light weight, Portable and Easy to carry on field
- Unique DO measurement in Air saturated waters using Conventional Polarographic Probe.
- Programmable Calibration upto 3 points for pH with Memory Back-up.
- Userful for Potentiometric & Redox measurements.
- Automatic / Manual Temperature Compensation.
- Accurate & Highly Stable.
- Elegantly styled into a Briefcase for operational convenience in Field.
- Operates on Rechargeable Battery & Mains Supply.
