Onset's H08-006-04 Data Logger monitors four different 4-20 mA or 0-2.5 VDC signals simultaneously. This four-input logger reads and stores up to 32,520 samples divided among the number of inputs being recorded. The H08-002-02 has an internal temperature sensor as well as a single-point external input that will accept a 4-20 mA or a 0-2.5 VDC input. The H08-003-02 has both an internal temperature and humidity sensor. Each external input requires a CABLE-4-20MA, a CABLE-2.5-STEREO, or a TMC6-HA temperature probe. A BOXCAR or BOXCAR PRO software kit is required to operate the H08 data loggers.
