Product Description

The HI991300 and HI991301 have been designed to offer pH, conductivity (EC), total dissolved solids (TDS) and temperature measurements in a slim, lightweight, and portable unit. From purified to brine water measurement, users can select the meter which will work best with the expected range of conductivity for greater precision. With just two buttons, users can select from a range of calibration buffers and even the temperature scale (C or F) that is most familiar. The housing is waterproof and rated for IP 67 conditions.
