Formerly Horiba B771
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）
Also known as:
Conductivity meter, EC meter, compact conductivity meter, compact EC meter, pocket conductivity meter, pocket EC meter, HORIBA EC meter, LaquaTwin conductivity meter, waterproof conductivity meter

*1 When the measured value is out of the measurement range, the displayed value blinks. It should be used only as a guide.
*2 Selectable between one-point and two-point calibrations. High conductivity standard solution (12.9mS/cm) is sold separately.
*3 IP67：no failure when immersed in water at a depth of 1 meter for 30 minutes. But the product can not be used underwater.
