Waterproof pH/EC/TDS/Temp Meter - 4 parameters with a single probe
- Stability indicator and hold feature
- Over 1500 hours of battery life
HANNA instruments offers you a choice of 2 meters to meet your exacting requirements. 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. 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 water proof and rated for IP 67 conditions. The multi-parameter probe, HI 1288, 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 (beta) 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.
HI 991300 is supplied complete with pH/EC/TDS/T HI 1288 probe, with 1 m (3.3') cable, batteries, rugged carrying case and instructions. |
