The HI9814 is a slim, lightweight, and waterproof portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single amplified probe. The meter operation is simplified with two buttons. One is used for on/off and for calibration while the other is used to switch between the measurement modes. The HI9814 has advanced features including an selectable EC to TDS conversion factor (0.5 - 500 ppm and 0.7 - 700 ppm).
3 in 1 amplified probe with pH, EC/TDS and temperature sensors
Quick Cal Mode to calibrate pH and EC/TDS with one solution
Conversion Factor (CF) selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
The HI1285-7 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. The pH portion of this probe is constructed with a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb. The EC/TDS portion of this probe utilizes two stainless steel pins for an amperometric determination of conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples. The design consideration for the HI1285-7 is ideal for measuring the pH, EC/TDS, and temperature in greenhouses, hydroponics, and other agricultural applications. The HI1285-7 is designed for use with Hanna’s HI9814 portable multiparameter meter.
