Hanna Instruments HI7698293 Long Calibration Beaker for GPS Multiparameter Meters

The Hanna Instruments HI 7698293 long calibration beaker holds buffer solution during the calibration process. The sensor is designed for use with the HI 9829 or HI 98290 GPS multiparameter meter and a compatible digital probe in environmental monitoring. During calibration, the threaded beaker is screwed onto the probe body. Text prompts during quick calibration indicate when to empty the beaker, when to shake the probe, and when to reinsert the probe in the beaker. Two beakers are recommended for each buffer solution: one for rinsing the sensor, and the second for calibration.

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.
