An Introduction is made of the working principles and technical specifications of digitalE601B evaporation sensors (AG11type ultrasonic，AG20type ultrasonic，FFZ01type digital，ZQZDV).Through comparing comprehensively the evaporation test data，the programming of total evaporation calculation，and the failure rate，the performances of the apparatus are discussed.The analysis results indicate that through improving the measuring environment and processing programs and reducing manual interventi〖JP2〗on， the antijamming capability of these new evaporation sensors under severe weather are improved，which makes allweather automatic precise evaporation observation possible and provides technical support for conducting automation evaporation observation in substitution for manual observation.
