Hanna Instruments HI7609829-1 pH/ORP Sensor with O-Ring, For Multiparameter Meter

The Hanna Instruments HI 7609829-1 pH/ORP sensor with O-ring provides temperature-corrected pH and ORP (oxygen reduction potential) or "redox" measurements for water quality monitoring. It is designed for use with the HI 9829 or HI 98290 GPS multiparameter meter and a compatible digital probe. The sensor has a glass pH-sensitive bulb for pH readings, and a platinum sensor for ORP measurements. This sensor is field replaceable and easy to attach, with color-coded screw-type connectors, a double-junction connector, and a solid gel-filled reference electrode to increase resistance to contamination. The HI 7609829-1 sensor measurements are International Organization for Standardization (ISO) 7027 compliant.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right.

A multiparameter meter is a benchtop or handheld device that can take multiple readings on a single sample. It measures parameters such as the pH level (acidity or alkalinity of a substance), conductivity (the amount of salts or other compounds present in water), dissolved oxygen (DO, the amount of oxygen in a liquid), temperature, total dissolved solids (TDS, anything present in water other than the pure water molecule and suspended solids), salinity, resistivity, and oxidation reduction potential (ORP). Applications for multiparameter meters include water testing, pharmaceuticals, agriculture, winemaking, water-treatment plants, and aquaculture. Devices with a benchtop body are often used for indoor laboratory use or in a manufacturing setting; handheld, portable devices are typically used for fieldwork. Sensors are used with a meter to measure the parameters of a substance.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.
