Product Description
The Hanna HI8615LN ORP Transmitter is a two-wire, water-resistant instrument engineered for reliable ORP (Oxidation Reduction Potential) measurements in harsh industrial environments. Featuring a galvanically isolated 4-20 mA output, this transmitter ensures accurate signal integrity by eliminating ground-loop and electrical interference, making it ideal for long-distance transmission in process automation setups.
This ‘L’ variant (HI8615LN) stands out with an integrated backlit LCD display—allowing real-time monitoring of process parameters directly on-site. Calibration is user-friendly and supports both offset (±0.8 mA/±100 mV) and slope (90–110% ±0.8 mA) adjustments to maintain top accuracy for demanding measurement needs.
- Durable, water-resistant design with IP65 housing to withstand challenging process and laboratory environments.
- Highly accurate ORP measurement with a range of 4-20 mA / ±1000 mV and fine resolution (1 mV for L models).
- Industrial-strength galvanic isolation of output signal for enhanced safety and noise immunity.
- Supplies calibration points for both offset and slope to facilitate precise operation.
- Accepts a wide range of ORP electrodes with a standard BNC connector for installation flexibility.
- Easy-to-read, backlit LCD for clear operation status and data visualization (HI8615LN only).
- Power supply requirements: 20–36 VDC for HI8615LN, assure compatibility with most industrial power sources.
- Operates within 0 to 50°C and up to 95% RH non-condensing, suitable for diverse process settings.
- Compact form factor of 165 x 110 x 71 mm, weighing approximately 1 kg, offers simple panel or wall-mounting.
This ORP transmitter is widely used in chemical plants, water treatment facilities, food & beverage, manufacturing lines, research laboratories, and other industries demanding robust and accurate redox potential monitoring and control. Process engineers and lab managers benefit from the reliable, interference-free signal and easy field calibration, all in a rugged protected housing.
