The OMYL-T11 and OMYL-T12 are temperature data loggers with internal temperature sensor that also accept external temperature inputs. These data loggers are available with standard memory of 100,000 readings (OMYL-T11, OMYL-T12) or expanded memory of 4 million readings (OMYL-T11-4M, OMYL-T12-4M). Integral Temperature Sensor Low Current Consumption High Accuracy
