The SL1000 series are high performance data logger with 16 bit resolution and up to twenty four channels. The channels are programmable via software and can be configured via to accept mA, mV, low level DC voltage and thermocouple sensors. There are two memory options, giving up to 500,000 readings at sample rates from once per second to once per day in one second increments. There is an eight channel variant that can perform high speed data logging, where all eight channels are scanned in 1mS. The SL1000 series can be configured to log 'off-line' to it's own internal memory, or, if connected to a computer, 'on-line', where the data are stored on the hard disk of the computer.
