Product Description

The HI98143 pH and EC Transmitter is a professional industrial instrument engineered for simultaneous measurement of pH (0–14) and electrical conductivity (EC, 0–10 mS/cm), featuring a fully isolated 4–20 mA (passive) analog output. Designed for remote process control in water treatment, hydroponics, laboratories, and industrial automation, it provides highly reliable and noise-resistant transmission of measurement signals for integration with a wide variety of PLCs and controllers.

This transmitter offers simple, direct probe connections: a BNC interface for the pH probe and an NTC sensor-integrated direct wire for EC, supporting four-ring EC/TDS probes for improved accuracy and stability across the measurement range. EC readings are automatically temperature compensated from 0 to 60 °C, ensuring reliable results in fluctuating environmental conditions. pH measurement features manual 2-point calibration via front panel trimmers for offset and slope adjustments.

Dual parameter transmitter: Measures both pH (0–14) and conductivity (0–10 mS/cm).
High-accuracy signal conditioning with ±0.5% f.s. (pH) and ±2% f.s. (EC).
Current loop output (4–20 mA, passive) for interference-free remote monitoring and integration.
Direct probe connections and IP54 enclosure for robust, low-maintenance operation in demanding industrial settings.
12–24 VDC supply for compatibility with standard process control infrastructure.
Automatic temperature compensation for EC via built-in NTC thermistor.
Manual pH calibration via accessible panel trimmers.
Compact and lightweight: 160 x 105 x 31 mm, ~0.28 kg.

Ideal for process industries, laboratory monitoring, environmental engineering, water and wastewater plants, and hydroponics. For more Hanna pH, EC, and industrial transmitter solutions, browse the complete range in the EnvMart catalog.
