VWR pHenomenal OX 4110 H Dissolved Oxygen Probe

VWR pHenomenal OX 4110 H handheld dissolved oxygen meter, designed for the measurement of dissolved oxygen and temperature in water samples and aquatic environments. The instrument uses an OPOX 11-3 optical oxygen probe with an integrated temperature sensor, providing accurate and high-resolution measurements for laboratory and field applications. Its robust IP67-rated housing, portable design, and battery operation make it particularly suitable for environmental monitoring and field sampling.

The system measures dissolved oxygen concentration, oxygen saturation, and temperature, with automatic temperature compensation and manual salinity compensation. It also features data logging, sensor diagnostics, a waterproof USB connection, and functions supporting Good Laboratory Practice (GLP), facilitating data recording and traceability.
