Key Features

Hanna HI98143 pH and EC Transmitter for industrial water quality monitoring, supporting 4-20 mA (active) isolated output.

Supports direct connection for pH probes with BNC and EC probes with built-in NTC sensor.
Offers dual channel input for independent pH (0 to 14) and EC (0 to 10 mS/cm) measurements.
4-20 mA (active) current loop isolated analog output for reliable remote process control integration.
Automatic temperature compensation for EC/TDS via integrated NTC sensor from 0 to 60 °C.
Manual two-point calibration for both pH and EC, enabling precise adjustments via trimmers.
High accuracy: ±0.5% f.s. for pH and ±2% f.s. for EC readings.
Tough IP54 enclosure suitable for industrial and hydroponic environments, with operating temperature 0–50°C.
Compact form factor with dimensions 160 x 105 x 31 mm.
Powered by 12–24 Vdc, making it suitable for panel, wall, or field installation.
Ideal for water treatment, hydroponics, and industrial laboratory process monitoring.

Product Description

Hanna HI98143 is an advanced pH and EC transmitter engineered for professional industrial, laboratory, and water treatment process monitoring applications. Designed with dual input channels, it supports both standard pH probes (BNC connection) and four-pole EC probes (direct wire with NTC sensor), making it versatile for remote operation and automated systems. The HI98143 model delivers isolated 4-20 mA (active) analog output for seamless integration into existing control panels and process loops.

Suited for hydroponic facilities, water treatment plants, and laboratory automation, the HI98143 ensures accurate measurement and control of pH (0–14) and electrical conductivity (0–10 mS/cm). The transmitter integrates automatic temperature compensation for EC/TDS measurements, maintaining high precision across varying process temperatures (0–60 °C) via an internal NTC thermistor sensor. Manual two-point calibration (through trimmers) for both channels enables operators to fine-tune accuracy and offset as needed.

Reliable, blind transmitter for industrial monitoring of pH and EC in water treatment, hydroponic, and laboratory environments.
Dual channel support for independent pH and EC measurements, each with manual two-point calibration.
Available analog output options for multiple process integration scenarios; HI98143 offers active 4-20 mA output.
IP54-rated enclosure ensures protection in harsh industrial conditions with max 95% relative humidity (non-condensing).
High accuracy: ±0.5% f.s. for pH, ±2% f.s. for EC, with trimmer-based calibration to compensate probe drift and environmental changes.
Compact and robust design dimensions: 160 x 105 x 31 mm; weight: 280 g.
12–24 Vdc power supply for flexible installation and integration.
This model is especially useful for remote processes demanding reliable, isolated output signals and stable, long-term performance, including in-line water quality systems, central monitoring stations, food industry, and research labs.

Applications: Water treatment, hydroponics, agriculture, manufacturing, laboratory process control, and environmental monitoring. Explore more Hanna water quality transmitters, process analyzers, and sensors on EnvMart.
