Although the storage module has been retired for many years, some replacement parts remain available (see Ordering Info). The SM192 was a battery-backed RAM storage module that stored both datalogger data and programs. It could store up to 96,000 low-resolution data points. Up to eight datalogger programs could also be stored in the module (program storage reduced available data storage). Although the SM192 has been retired for many years, replacement parts remain available (see Ordering Info).
