Product Description

The HI9814 is a portable, waterproof multiparameter meter designed for hydroponics, aquaponics, and greenhouse applications. It accurately measures pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature in nutrient solutions, helping ensure optimal plant health and growth.

  • This compact device features a 3-in-1 amplified probe (HI1285-7) with built-in temperature sensor, providing fast and precise measurements for essential water parameters.
  • Automatic calibration options for pH and EC/TDS make it user-friendly and reduce errors during setup.
  • Select between EC to TDS conversion factors of 0.5 (500 ppm) or 0.7 (700 ppm), covering a wide range of growing methods.
  • IP67-rated waterproof housing allows for use in challenging horticultural or industrial environments.
  • The LCD display with diagnostic icon for probe condition ensures consistent and reliable operation.
  • Quick Cal Mode simplifies pH and EC/TDS calibration with one solution, saving both time and resources.
  • Automatic shut-off after 8 or 60 minutes preserves battery life.
  • The instrument offers ±0.02 pH, ±2% EC/TDS accuracy, and 0.1°C temperature resolution for meticulous solution control.
  • Suitable for continuous field measurements, lab calibration protocols, industrial water testing, and greenhouse nutrient management.

Applications include hydroponics, aquaponics, greenhouse water and nutrient management, research, and agricultural quality control. Supplied with HI1285-7 probe, batteries, and user manual. Estimated weight: 0.196 kg. Dimensions: 154 x 63 x 30 mm.
