The HI-99300 is a portable EC/TDS/temperature meter designed for measuring low-range conductivity in µS/cm and TDS in ppm. Encased in an IP67-rated housing, it is highly durable and suitable for challenging conditions.

This instrument features single-point, automatic calibration and provides temperature-compensated measurements. Users can select the compensation coefficient and EC/TDS conversion factor within the range of 0.45 to 1.00, and the temperature coefficient can be adjusted from 0.0 to 2.4%/°C.

Compact enough to fit comfortably in the palm of your hand, the HI-99300 has a bottom probe connection to prevent the electrode cable from getting in the way. Its large, multi-level LCD displays the primary reading, temperature, and calibration guides simultaneously, with symbols and messages indicating meter status and guiding users through operations.

Upon start-up, the meter displays the remaining battery percentage. A battery symbol appears on the LCD to alert users when the battery is low, indicating only a few hours of operational time remain.
