Dickson* SK4 and SL4 Temperature Chart Recorders

Ideal for monitoring areas where proper temperatures are critical to products. They are designed for use in laboratories and storage facilities. They can be placed directly into the environment being monitored. Both the SL4 and SK4 units contain a spiral wound bimetallic strip transducer. Portable and easy to use, recorders feature a corrosion-resistant case. These recorders were designed for use in areas were recording long term temperature trends is most important. The SL4 models feature an easy to read digital display. SK4 models have no digital display.
