  • Resistance
  • 4-20mA signals

Record Anywhere

The standard logger’s 8 differential (16 single-ended) universal analog inputs connect to many different sensor types. The SQ2020 data logger also features 2 high voltage, 4 pulse rate/counter inputs and 8 digital event/state inputs taking measurements at a high 0.05% precision. 4 alarm/relay outputs connect to alarm lights or sirens to notify users on alarm conditions.

For convenient data collection, Squirrel data loggers feature USB and RS232 connectivity, and onboard RS232 communications features can also be connected to a PSTN or GSM modem.
