Hanna Instruments HI991301 Portable Waterproof pH/EC/TDS Meter (High Range)
The HI991301 is a single probe that can measure temperature, conductivity (EC), pH, and total dissolved solids (TDS). Just two buttons are used to complete every operation, from setup to calibration. The meter has an IP 67 rating and is waterproof.
The HI12883 pre-amplified multiparameter probe has a sensor that is simple to clean and a cloth junction that can be replaced to extend the probe’s lifespan. The HI12883 includes a solid-state amplifier to protect against interference from transient electrical noise.
For increased consistency and reproducibility, user-selectable features include a variety of TDS factors from 0.45 to 1.00 and a range of temperature coefficients () from 0.0 to 2.4%. Additionally configurable are standardized buffer recognition values.
The bottom probe connection makes sure the electrode cord doesn’t get in the way, and these instruments sit comfortably in the palm of your hand. The primary reading, temperature, and calibration instructions are all displayed simultaneously on the big, multi-level LCD.
