Each logger incorporates a red and green LED, the flashing green LED indicates that the logger is active/logging and the flashing red LED indicates that your customised preset alarms have been exceeded. The WTB data logger incorporates an internal NTC thermistor sensor. This RF data logger records temperature over the range of -40 to 85 °C and can record up to 16000 readings. The RF ThermaData wireless data-logging system consists of a number of RF (wireless) data loggers, a RF base station connected to a PC and software which enables the user to upload data or download programme information to each logger. The RF loggers are housed in a waterproof, ergonomic case that is designed to meet IP66/67 protection. Each RF logger is a self-contained, battery powered unit that can receive, log, store and transmit data to the RF receiver. Options include internal and external temperature sensor/ probe/s. The external probes can be either fixed or detachable via a waterproof three-pin connector. The remote temperature probes are supplied with a one metre PVC/PFA (fixed) or PUR/PVC (detachable) lead. * All wireless loggers require 293-805 Base Station to operate.
