Hanna* Portable and Waterproof pH/Conductivity/TDS/Temperature Meters

Welcome the new generation of unparalleled versatility and simplicity in pH, EC and TDS measurements. The HI 991300 and HI 991301 offer you the combination of pH, electro-conductivity, total dissolved solids and temperature measurements. To increase precision, you can select the meter which will work best with your range of conductivity, from purified to brackish waters. The housing is waterproof and rated for IP 67 conditions. The multi-functional probe includes pH, EC/TDS and temperature in one convenient, rugged handle.

Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (b) from 0.0 to 2.4% for greater consistency and reproducibility. Also selectable are standardized buffer recognition values. To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the probe.

Meters are supplied complete with pH/EC/TDS/°C probe, batteries, instruction manual and a hard carrying case.
