Smart TDS & Conductivity Meter (3 point calibration)


Galaxy TDS-100 is an auto-ranging microprocessor Conductivity/TDS Meter for measuring the conductivity & TDS of liquids. It’s 3 point digital calibration & auto buffer recognition makes it a favorite among lab users. It is widely  used in environmental & ecological studies for monitoring the purity and concentration of liquids.
