Extech SDL150 Dissolved Oxygen Meter Datalogger with SD Card

The Extech SDL150 Dissolved Oxygen Meter/Datalogger is a professional-grade instrument designed for accurate monitoring of oxygen levels in liquids. Ideal for laboratory, environmental, and industrial applications, this handheld meter measures both dissolved oxygen concentration and temperature simultaneously, ensuring comprehensive analysis in a single device.

With a dual backlit LCD display, the SDL150 shows real-time readings of oxygen levels and temperature for immediate interpretation. The built-in datalogging function enables storage of up to 99 manual readings and 20 million readings on the included 2G SD card, allowing for long-term monitoring and data review.

A polarographic oxygen probe with automatic temperature compensation ensures precise measurements across a broad temperature range. Additional features such as Min/Max capture, Data Hold, and user-programmable sampling rates make the SDL150 a highly adaptable tool for a variety of field and lab scenarios.
