INCINERATOR TRITIUM SAMPLER

摘要

PROBLEM TO BE SOLVED: To provide an incinerator tritium sampler having excellent long period stability dispensing with frequent calibration of a moisture amount measuring means and exchange of a detection element of the moisture amount measuring means accompanying it. SOLUTION: The incinerator tritium sampler arranges a cooling device 14 and a specimen water collecting weighing vessel 15a for collecting to dew-condense moisture in an exhaust at a suction side of a monitoring object exhaust, and arranges a moisture measuring part 12 and a flowmeter 18 for incorporating hygrometers or dew points afterward thereof. The incinerator tritium sampler calculates a collection moisture amount in the exhaust of a prescribed volume from moisture amount data collected in the specimen water collecting weighing vessel 15a and flow rate data of the flowmeter 18, calculates a residual moisture amount in the exhaust of the prescribed volume from the residual moisture amount data in the exhaust passing the cooling device 14 obtained with the moisture amount measuring part 12, and calculates an entire moisture amount in the exhaust of the prescribed volume by adding both.
