4-in-1 waterproof multi-parameter instrument for measuring pH, conductivity, TDS and temperature in one easy to use meter, utilising a single replaceable probe. This meter is available in two models with different EC ranges - select the meter which will work best with your range of conductivity, from purified to brackish waters. The Low Range model measures EC from 0-3999 uS/cm and TDS from 0-2000 mg/l and the High Range model measures EC from 0-19,99 mS/cm and TDS from 0-10.000 mg/l.
There are only 2 buttons, yet you can select from a range of calibration buffers and even the temperature scale (C or F) most familiar to you. The housing is waterproof and rated for IP 67 conditions.
Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4% for greater consistency and reproducibility. Also selectable are standardized buffer recognition values.
The multi-parameter probe includes pH, EC/TDS and temperature in one convenient, rugged handle. To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the probe.
The HI-991300 is supplied with pH/EC/TDS/T HI 1288 probe, with 1 m cable, batteries, rugged carrying case and instructions.
