Extech SD200 3-Channel Temperature Datalogger

This instrument gives you simultaneous read‑out of up to three Type K thermocouple inputs (T1, T2, T3) via a large triple‑LCD display.The unit stores logged data on an SD memory card in a format compatible with Excel, so you can easily transfer and analyse your results on a PC.You can set the sampling interval to various speeds (5, 10, 30, 60, 120, 300, 600 seconds, or in “AUTO” mode where logging triggers when temperature changes by more than 1 °C) for flexibility in how you monitor conditions. The temperature range when using Type K probes is approximately −100 °C to +1300 °C (or −58 °F to +2372 °F) depending on the probe, giving you broad coverage across many applications. Power is supplied either via six AAA batteries or a universal AC adaptor, and the meter features additional functionality such as date/time stamps on logged entries, USB/RS232 output for connectivity, and a tilt‑stand or mounting option.

Features

• Simultaneous display of three Type K thermocouple channels (T1/T2/T3) on a triple‑LCD screen.

• Data logging to SD card (supports 1 GB–16 GB cards) in Excel (.XLS) format for easy PC analysis.

• Selectable sampling intervals: 5, 10, 30, 60, 120, 300, 600 seconds or AUTO mode.

• Wide temperature range for Type K probes: approximately −100 °C to +1300 °C (−58 °F to +2372 °F) with resolution 0.1° and accuracy ~±(0.5% +1 °C) for standard range.

• USB/RS‑232 interface for data transfer, plus the large display and multiple probe inputs for flexibility.

• Battery powered (six AAA) or AC adaptor option for longer term deployments.

• Memory card formatting, real‑time clock for timestamping readings, and “AUTO” logging based on temperature change for efficient data capture.

• Tilt‑stand and mounting kit included, making it suitable for both bench‑top and wall/fixture installation.
