Optical dissolved oxygen sensor

process

Handheld meters can range in form factor, desired parameter(s), and functions to enable measurements across different applications. For form factor, meters can be fully handheld without cables (an all-in-one option with a sensor built-in to the meter) or with cables where sensors can be easily interchanged. As an example, AlpHa’s optical dissolved oxygen handheld meter offers both laboratory and field / process sensors for multiple applications. The handheld meter offers characteristics of high precision and high stability: Resolution down to less than 1 ppb Built-in automatic temperature compensation Built-in automatic pressure compensation 1-point and 2-point calibrations for ppm and ppb measurement Salinity auto compensation with user input
