Dissolved Oxygen Meters

Milwaukee Mi190 Extended Range Bench Dissolved Oxygen Meter

The Mi190 is ideal for testing Dissolved Oxygen in the pharmaceutical and food industry, as well as monitoring in water treatment plants. The user can choose to measure D.O. readings in mg/L or % of saturation of O2.
This mater can be used for ant type of water, as is allows measurements to compensate for temperature, altitude and salinity factors. The automatic logging interval can be used to perform analysis and store data into the memory.
All logged data can be downloaded to the user’s PC through an RS232 or USB serial port. Memory can store up to 50 samples. The Mi190 features an automatic calibration procedure at 1 or 2 points (at 0 and 100% of O2 saturation). The polarographic probe supplied with the meter (MA840/2) measure the current generated by the reaction of O2  with Ag.
