Dissolved Oxygen Meters
Raptor Supplies brings you high-quality DO meters from brands like Oakton, Extech and YSI used to determine the amount of dissolved oxygen in a liquid. Extech SDL Series meters or data loggers feature a dual display that shows the oxygen concentration from 0 to 20.0 mg/L and 0 to 100 per cent, as well as temperatures ranging from 32 to 122 degrees F (0 to 50 deg C). These units store readings with the date and time stamps on an SD card (included) in Excel format that can be easily transferred to a PC and further come equipped with 6 AA batteries, a probe, a spare probe head with a diaphragm and a case.To provide years of sampling even in the harshest field conditions, YSI dissolved oxygen meters are best suited because of their 1-metre drop test assurance and IP67 waterproof & rubber-over molded case. The brand's EcoSense line of handheld instruments have polarographic or galvanic DO sensors that allow quick sampling and a One Touch Cal facility capable of calibrating within 3 seconds with just the push of a button.
