Are you looking for a reliable and versatile thermometer logger for your projects? The Extech SDL200 Four-Channel Thermometer Logger might be the perfect solution for your needs. With its ability to handle multiple thermocouple types and RTD probes, this logger is both powerful and user-friendly. Let’s dive into its features and performance to see if it meets your expectations.
Features and Capabilities
Multi-Channel Datalogging
The Extech SDL200 shines with its multi-channel datalogging capability. It supports four different channels, which means you can monitor up to four separate temperature points simultaneously. This is incredibly useful for applications that require comprehensive temperature monitoring.
Supported Thermocouple Types
One of the standout features of the SDL200 is its compatibility with six different thermocouple types: J, K, E, T, R, and S. This level of versatility ensures that you can use the right type of thermocouple for your specific needs, whether it’s for industrial applications or laboratory experiments.
RTD Probe Compatibility
In addition to thermocouples, the SDL200 also supports 2-channel datalogging with RTD (Pt100 Ohm) probes. RTD probes are well-known for their high accuracy and stability, making them ideal for applications where precision is crucial.
Display Options
The temperature readings can be displayed in various formats. You can choose to view individual channel readings (T1, T2, T3, T4) or differential readings (T1 – T2). This flexibility allows you to tailor the display to your specific monitoring requirements, making data interpretation easier.
Datalogging and Memory Storage
One of the most convenient features of the SDL200 is its built-in datalogging function. The device date/time stamps and stores readings on a memory card in Excel format. This makes it incredibly easy to transfer your data to a PC for further analysis. The stored data is neatly organized, so you won’t struggle with complicated file formats.
Offset Adjustment
The device includes an offset adjustment function that can be used for zeroing, enabling you to make relative measurements. This can be particularly handy when you need to compare readings without any baseline noise, enhancing the overall accuracy.
