The Extech SDL150 saves data to an SD card in Excel format. It features a dual backlit display for oxygen concentration and temperature. It monitors dissolved oxygen from 0 mg/L to 20.0 mg/L, 0% to 100% oxygen, and temperature from 0°C to 50°C (32 to 122°F). Includes automated temperature correction from 0°C to 50°C via a temperature probe sensor included into the polarographic type oxygen probe. Offset adjustment is used for the zero function to provide relative measurements. The SDL150 can save 99 measurements manually and 20M readings using a 2GB SD card. User-programmable sampling rate. It includes a built-in PC interface, min/max and data hold functions, and an auto power down feature. Includes 6 AA batteries, SD card, probe, two spare replacement membranes, electrolyte, and hard
