AZ Conductivity & TDS Pen

The AZ Conductivity & TDS Pen measures the conductivity, TDS (Total Dissolved Liquid), and temperature of your solution target.
This Pen is designed to be auto-ranging when powered on. Auto-ranging determines and selects a range, allowing control over the greatest resolution and accuracy.
The AZ Conductivity & TDS Pen can be easily calibrated by the user.   Its portable housing design means you can take this anywhere at anytime.
The AZ Conductivity and TDS Pen is the best water quality tester for professional measuring purposes, such as lab activity, water treatments, aquaculture and hydroponics.
