Product Applications
These units are self-contained temperature recorders. The SK4 & SL4 recorders are portable, easy-to-use
and provide a permanent record of temperatures. These recorders have locking door and built-in slot for an
optional tie-down cable and lock.
The SK4 was designed for use in applications where recording long term temperature trends is most important.
The SL4 was built to give you the best of both worlds: a permanent record of long term temperature
recording combined with an easy-to-read, digital display.
