Portable EC/TDS meter high range
Hanna Instruments HI-99301 Portable EC/TDS/Temperature Meter — High Range
The Hanna Instruments HI-99301 is a portable, IP67-rated EC/TDS/temperature meter measuring high range conductivity in mS/cm and TDS in ppt, making it the ideal companion to the HI-99300 where higher conductivity and dissolved solids levels are encountered. The updated instrument features a larger, user-friendly LCD, on-screen tutorial messages for calibration and setup, a missing probe indicator, a rugged ergonomic casing, faster battery replacement and a bottom-mounted probe connection that keeps the electrode cable clear of the work area. The large multi-level LCD displays the primary reading, temperature and calibration guides simultaneously.
Single point automatic calibration with automatically temperature compensated measurements is standard, and both the EC/TDS conversion factor (0.45 to 1.00) and temperature compensation coefficient (0.0 to 2.4%/°C) are user-selectable. The BEPS Battery Error Prevention System alerts the user if low battery power could adversely affect readings, and battery percentage is shown on start-up. Each meter is supplied complete with the HI-763063 EC/TDS/temperature probe, calibration solution sachets, a 100ml beaker, batteries, a rugged carrying case, and calibration certificates for both meter and probe.
