HI 9147-04
Oximeter with galvanic sensor and backlit display, cable 4 meters

Oxycheck is a portable meter DO water resistant to manual calibration; possesses a fixed probe and executes the compensation of temperature and salinity.
HI 9147-04 has an inductive system of charging the battery which prevents any possible infiltration of water.
DO readings are automatically compensated for the effects of temperature data on the solubility of oxygen and on the membrane permeability, thanks to the internal sensors to the probe. The salinity compensation allows to determine the DO even in salt water and can also be used as altitude compensation.
The instrument is constructed with sturdy water resistant material which makes it suitable both to measurements in the field or in the lab.
probe is equipped with a galvanic sensor that, unlike the polarographic, no need for times of polarization when the instrument.
