Compact Conductivity Meter
- Horiba - LAQUAtwin B-771
- Conductivity：0 to 19.9 mS/cm (0 to 1.99S/m)
- Salt：0 to 1.1 %
- TDS：0 to 9900 ppm
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.
- Fresh water testing (rain, rivers, lakes, hot springs)
- Soil testing for improved agriculture and analysis of salt water damage
- Analysis of surface cleanliness prior to coating
- Improved paint adhesion.
- Salt/TDS Measurement
- Auto range change
- Temperature conversion(2%/℃ fixed)
- IP67 waterproof
- Auto hold
- Automatic power off（15 minutes）
- Conductivity Sensor S070
- Standard solution (Conductivity 12.9 mS/cm) Y071H
- Standard solution (Conductivity 1.41 mS/cm) Y071L
