DESCRIPTION

Designed for hydroponic, aquaponic, and greenhouse growers

The HI9814 features many advanced functions typically found in more expensive portable meters, including automatic calibration, buffer/standard recognition, and temperature compensation. A tutorial message on the screen, along with indicators for calibration status and stability, can be viewed on the large multi-level LCD display.
  • Compact and sturdy housing
  • Simultaneous reading of pH, EC or TDS, and °C
  • Specialized multi-parameter electrode
  • Optional green rubber protective case (HI710025)

The HI9814 comes with the specialized HI1285-7 electrode, which offers the following key benefits:

Pre-amplified pH electrode: prevents interference from moisture and electrical noise sources, including circulation pumps, motors, and grow light ballasts.
Amperometric EC/TDS sensor: EC/TDS readings are taken using a two-pin amperometric sensor, ideally suited for low-conductivity applications.
Integrated temperature sensor: pH and EC/TDS readings must be temperature-compensated to ensure accurate results. The integrated temperature sensor provides a rapid temperature reading, which is then used to adjust the pH and EC/TDS results for greater accuracy.
