Extech Four-Channel Thermometer SD Logger SDL200

Extech SDL200 Precision 4-Channel Thermometer and RTD Data Logger

Capture and analyze critical temperature data with an advanced 4-channel system that exports directly to Excel, ensuring seamless monitoring for complex environmental and industrial applications.

The Extech SDL200 is a professional-grade monitoring solution designed to provide deep insight into thermal dynamics across diverse environments. By supporting six different thermocouple types and dual RTD probes, this versatile logger allows researchers to track four distinct channels simultaneously or focus on differential temperature changes (T1-T2). Whether you are monitoring delicate forest soil temperatures, industrial heating processes, or aquatic habitats, the SDL200 simplifies data management by logging up to 20 million readings directly onto an SD card in an Excel-ready format. Its user-programmable sampling rate and real-time clock ensure that every fluctuation is captured with precision, making it an indispensable tool for long-term field studies and laboratory analysis.

Key Features

• Multi-Channel Versatility: Supports 4-channel logging with thermocouples (J, K, E, T, R, S) and 2-channel logging with RTD probes.
• Effortless Data Management: Logs data directly to a 2GB SD card in Excel format for easy PC transfer without specialized software.
• Massive Storage Capacity: Capable of storing 20 million readings with real-time date and time stamps for long-term monitoring.
• Differential Analysis: Displays individual readings for all channels or the differential value (T1-T2) for relative temperature tracking.
• Programmable Sampling Rate: Allows users to set data capture intervals from 1 second to 3600 seconds to fit specific project needs.
• Advanced Measurement Tools: Features Min/Max tracking, Data Hold, and an offset adjustment for high-accuracy zero functions.
