The newest meter line from Thermo features a large, backlit graphic LCD for measuring dissolved oxygen in percent saturation or concentration along with temperature. Additional features include electrode status, time, date and calibration data.
Plain language screen prompts and AUTO-READ makes taking measurements easy. Non-volatile memory stores up to 1,000 data points with time and date stamp. Easily transfer data or update meter software via the USB and RS-232 ports.
Calibrate using air-saturated water, water-saturated air or a Winkler titration. Meter accepts both traditional polarographic sensor or the new RDO sensor that eliminates flow dependence, warm up time and membrane/electrolyte changes. Temperature compensation is automatic and salinity and pressure compensation can be achieved manually.
Meter kit includes087010MD RDO probe with 3 m cable, stainless steel probe guard, calibration sleeve, protective meter amror with electrode holder, carrying case, 4 AA batteries and meter software.
