On 26th of October IPM launched a continuous operation test. The laboratory tests will allow determining the exact life time span of the sensor before maintenance is required. The sensor is now being tested by an automatized laboratory setup under harsh environmental conditions with a very high sampling rate of one sample measurement every second. After a week of operation, the sensor is giving promising indications about a robust life time and about the quality of the technique developed at IPM. The system will be kept operational to extract more data before changing the sensor in the testing system.
