The HI 98140 and HI 98150 Waterproof pH/ORP/°C Meters feature "intelligent" electrodes and log-on-demand. The product's ABS housing provides the instrument with rugged, waterproof construction, and the slope, offset, date, and time of last calibration is stored automatically in the electrode itself, allowing the meter to utilize many different electrodes without recalibrating.
The device's extended pH range is 4-19.99 pH, and the dual level backlit LCD offers optimal visibility of measurements. Additional features include five memorized buffers, and the meter prompts the user when the electrode must either be reconditioned or replaced based upon the slope and offset measured.
