DR Labs DR-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..
SALIENT FEATURES:
• Large back light LCD display shows mode indicator, TDS or EC value, temperature
