Hanna Instruments – HI9810-6 Portable pH/EC/TDS Meter

The HI9810-6 Portable pH/EC/TDS Meter from Hanna Instruments is a reliable and cost-effective multiparameter meter designed for measuring pH, Electrical Conductivity (EC), and Total Dissolved Solids (TDS) using a single probe. With ±0.1 pH accuracy, automatic temperature compensation, and a durable water-resistant casing, it is ideal for agriculture, hydroponics, and greenhouse applications. The meter features manual one-point calibration, dedicated measurement buttons, and a large LCD for straightforward operation in field environments.

  • 3-in-1 Multiparameter Probe (pH, EC/TDS & Temperature)
  • Amplified pH Electrode for Electrical Noise Immunity
  • Automatic Temperature Compensation (β = 2%/°C)
  • Designed for Agriculture, Greenhouse & Hydroponics Use

Description

The HI9810-6 is a portable, water-resistant meter engineered to measure pH (0–14 pH), EC (0–6000 µS/cm), and TDS (0–3000 mg/L) accurately and efficiently. Featuring 0.1 pH resolution with ±0.1 pH accuracy, along with ±2% F.S. accuracy for EC and TDS, this meter provides dependable readings for nutrient solution monitoring and water quality management. Automatic temperature compensation (0 to 50°C) with a correction coefficient of β = 2%/°C ensures consistent measurements even when temperature fluctuates.

Equipped with the HI1285 amplified multiparameter probe, the meter integrates a double-junction gel pH electrode, EC/TDS sensor, and built-in temperature sensor in a single rugged probe with a 1-meter cable. The amplified electrode design protects against electrical interference from pumps, ballasts, and other equipment commonly used in hydroponic systems. With dedicated buttons for each parameter, simple manual one-point calibration via trimmers, and a large LCD display, the HI9810-6 offers user-friendly operation and dependable performance for professional growers and agricultural users.

Features

  • 3-in-1 Multiparameter Probe (HI1285) – Measures pH, EC, TDS, and temperature with a single amplified probe.
  • Amplified pH Electrode – Provides immunity against electrical noise from pumps and ballasts.
  • Automatic Temperature Compensation – 0 to 50°C with β = 2%/°C for accurate EC/TDS readings.
  • Wide Measurement Ranges – pH (0–14), EC (0–6000 µS/cm), TDS (0–3000 mg/L).
  • Manual One-Point Calibration – Simple calibration via offset trimmers for pH and EC/TDS.
  • Large LCD Display – Clear reading display with dedicated buttons for each measurement mode.
  • Water-Resistant Portable Design – Durable casing ideal for agriculture and hydroponic applications.
