Product Description

HANNA HI 991300 PH/EC/TDS

The HANNA HI 991300 is a slim, lightweight, and waterproof portable meter that measures pH, conductivity (EC), total dissolved solids (TDS), and temperature with a single amplified probe. Ideal for agricultural, greenhouse, and hydroponics applications, this meter features a large, multi-level LCD that displays both the primary reading and temperature simultaneously. It offers automatic one or two-point pH calibration and automatic one-point EC/TDS calibration. The HI 991300 also features Automatic Temperature Compensation (ATC) for all parameters, a stability indicator, and a low battery indicator. The included HI1285-51 multi-parameter probe incorporates pH, EC, TDS, and temperature sensors in one convenient, rugged body.
