Hanna Instruments Water Analysis Division has released the HI 991300 and HI 991301, offering the combination of pH, electro-conductivity, total dissolved solids and temperature measurements.

To increase precision the user can select the meter which will work best with your range of conductivity, from purified to brackish waters. There are only two buttons, but the user can select from a range of calibration buffers and even the most familiar temperature scale (°C or °F). The housing is waterproof and rated for IP 67 conditions. The HI 1288 multi-parameter 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 (ß) from 0.0 to 2.4% for greater consistency and reproducibility. Also selectable are standardised buffer recognition values. To guard against interference from transient electrical noise, a solid-state amplifier is integrated into the probe.

The HI 991301 is supplied with a pH/EC/TDS/T HI 1288 probe, a 1m cable, batteries, a rugged carrying case and instructions.
