Extech EC701 vedenlaadun mittauslaite johtavuudelle, TDS:lle, suolapitoisuudelle ja lämpötilalle

Monitoring water quality across multiple parameters can be cumbersome with separate instruments, but the Extech EC701 consolidates conductivity, TDS, salinity, and temperature measurements into one portable, waterproof device. Its flat-surface electrode is replaceable and easy to clean, making it suitable for field and lab use.

Who is it for

This meter is ideal for environmental technicians, aquarium hobbyists, hydroponic growers, and water treatment professionals who need reliable, on-the-spot water analysis without carrying multiple tools.
