Product Description

The HI8614LN pH Transmitter with 4-20 mA galvanically isolated output is a robust and water-resistant industrial instrument designed for precise pH monitoring in process control, water treatment plants, and other demanding environments. Compatible with high impedance pH probes featuring BNC connectors, it includes a special high impedance amplifier to ensure that the output is directly proportional to the input, regardless of load or cable length. The HI8614LN model stands out with its optional backlit LCD display for real-time readings, offering user-friendly operation and field diagnostics.

Water-resistant, two-wire design ideal for long-distance signal transmission and remote process monitoring.
Analog 4-20 mA output is galvanically isolated, reducing interference and improving measurement reliability across installations.
Supports fixed and automatic temperature compensation from 0 to 100°C, using a compatible probe such as the HI76608, for consistently accurate readings in variable process temperatures.
Industrial-class enclosure with IP65 rating protects components from dust, process splashes, and harsh environmental conditions.
Offers high accuracy of ±0.02 pH and ±0.02 mA, appropriate for critical laboratory, process, and water quality applications.
Offset and slope (86% to 116%) calibration options allow for precise tuning to specific site requirements.
Dimensions of 165 x 110 x 71 mm (6.5 x 4.3 x 2.8 inches) allow for easy integration in control panels or field mountings.
Operates within 0 to 50°C ambient temperature, with relative humidity up to 95% (non-condensing).
Power supply requirement is 20–36 VDC (HI8614LN), suitable for standard industrial power systems.
Industrial, water and wastewater treatment, food and beverage, chemical processing, and laboratory automation are some key application sectors.

This transmitter is ideal for customers seeking reliable, isolated pH signal output with advanced compensation, easy calibration, and durability in industrial use. The set includes the pH transmitter and documentation. For more process instruments, browse the EnvMart Measuring & Testing Instruments category.
