HANNA HI 99301 WATERPROOF EC/TDS/TEMPERATURE METER WITH AMPEROMETRIC TECHNOLOGY
HI 99301 is one innovative meter that combines measurements of conductivity, TDS (Total Dissolved Solids) and temperature. The housing is water-resistant and rated for IP 67 conditions.
The meter is provided with advanced features, designed for quick and easy field operation.
The multi-functional HI 76306 probe measures EC/TDS and temperature in one rugged unit. EC (or TDS) and temperature readings are displayed simultaneously. Moreover, symbols and messages on the LCD indicate the meter status and guide the user through operations.
At start-up, the meter shows the remaining battery percentage and when a low battery condition is detected, a battery symbol appears on the LCD to advise the user that only a few hours of working time is left.
The meters are also provided with BEPS (Battery Error Prevention System), which turns the meter off when the battery level is too low, to assure reliable readings. Calibration is a single point automatic procedure and measurements are automatically compensated for temperature variations. The compensation
coefficient and the EC/TDS conversion factor are user-selectable. All settings and calibration data remain in memory when changing batteries.
