Description
The HI99300 Low Range EC/TDS Meter is designed for measurements in pure and low ionic strength water applications. The specialized HI99300 probe features EC/TDS and temperature in one convenient, rugged probe for low range EC measurements from 0 to 3999 µS/cm and TDS measurements from 0 to 2000 ppm.
- ±2% EC/TDS Accuracy
- Perfect for water quality testing in manufacturing and environmental industries.
Low Battery Indicator
The included batteries provide 500 hours of continuous use. When the battery level is below 10%, a warning symbol will blink to indicate low battery condition. When low battery power may affect your results, the meter will shut down to avoid erroneous readings caused by low battery level.
Two Measurement Modes
HI99300 offers two measurement modes: EC and TDS. Users can easily switch between measurement modes with a simple press of the MODE button. EC measurements range from 0 to 3999 µS/cm; TDS measurements range from 0 to 2000 ppm.
