Waterproof portable conductivity (EC) up to 20 mS / cm | S/M

The new and improved HI-99301. With it’s larger user friendly LCD, tutorial messages for calibration and setup, missing probe indicator, newer rugged ergonomic casing, faster and easier battery replacement and probe situated on the bottom of the instrument for ease ot use, the updated model is much more effiecent.
The HI-99301 is a portable, EC/TDS/temperature meter that measures high range conductivity in mS/cm and TDS in ppt. Both instruments are housed in a case rated for IP67 conditions.
This instrument offers single point, automatic calibration with automatically temperature compensated measurements. The compensation coefficient and EC/TDS conversion factor are user-selectable from 0.45 to 1.00 and temperature coefficient is selectable from 0.0 to 2.4%/°C.
This meter easily fits in the palm of your hand and the bottom probe connection ensures the electrode cable doesn’t get in your way. The large, multi-level LCD displays the primary reading, temperature and calibration guides simultaneously. Symbols and messages on the LCD indicate meter status and guides users 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 HI-763063 EC/TDS/temperature probe resists clogging and is easy to clean.
Ideal for: Boiler Water & Waste Water
