Feature
Conductivity and TDS measurement. Autoranging & temperature compensation for higher accuracy.
Overview
Determine water conductivity with as little as 0.12 mL of sample.
The conductivity of rain water is a trusted guide to determining atmospheric purity. In agriculture, measuring the conductivity of soil allows farmers and agronomists to determine optimum fertiliser usage and check the ‘health’ of soil after salt water damage. The LAQUAtwin meter makes conductivity testing simple, anywhere.
Applications include:
Fresh water testing (rain, rivers, lakes, hot springs); aquaria; soil testing for improved agriculture and analysis of salt water damage; analysis of surface cleanliness prior to coating; and improved paint adhesion.
Functions
- Salt/TDS Measurement
- Auto range change
- Temperature conversion(2%/℃ fixed)
- IP67 waterproof
- Auto hold
- Automatic power off(15 minutes)
