Description
The HI9811-5 is a compact and waterproof portable meter engineered to simultaneously measure pH (0–14 pH), EC (0–6000 µS/cm), TDS (0–3000 ppm), and temperature (0.0–70.0°C). With 0.1 pH resolution and ±0.1 pH accuracy, along with ± 2% F.S. accuracy for EC and TDS, it provides dependable monitoring of nutrient solutions and water quality. Automatic temperature compensation from 0 to 50°C with a correction coefficient of β = 2%/°C ensures consistent EC and TDS readings under varying environmental conditions.
The meter features the HI1285-5 amplified multiparameter probe, integrating a pH electrode, EC/TDS sensor, and built-in temperature sensor into one durable probe with an 8-pin DIN connector and 1-meter cable. The amplified electrode design minimizes electrical interference from pumps and ballasts, making it ideal for hydroponic and greenhouse systems. Dedicated buttons for each measurement mode, manual one-point calibration via trimmers, and a large LCD display enhance ease of use, while the rugged carrying case ensures safe transport and storage.
