DO Meter | Dissolved Oxygen Meter | Oxygen Meter

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 meter can be used for any type of water, as it allows measurements to compensate for temperature, altitude and salinity factors. The automatic logging interval can be set to perform analysis and store data into the memory.

All logged data can be downloaded to your PC through an RS232 or USB serial port. Memory can store up to 50 samples. 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) measures the current generated by the reaction of O2 with Ag.

Mi-190 is supplied complete with MA840/2 DO probe with 2 m cable, 2 spare membranes, MA7041 electrolyte solution (30 mL), 12 VDC power adapter, probe holder and instruction manual.
