Full Description Specification Manuals

The HI-99300 is a portable, EC/TDS/temperature meter that measures low range conductivity in µS/cm and TDS in ppm. It is 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.

The 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-76306 EC/TDS/temperature probe resists clogging and is easy to clean.
