PURPOSE:To facilitate the sampling of a plurality of samples by turning a rotary base to connect a plurality of sample introduction channels arranged thereon sequentially to one sample introduction path provided on a fixed base after a plurality of sample containers are connected to the respective sample introduction channels. CONSTITUTION:When sampling the oil of a transformer, twelve sample containers 15 filled with a sample oil are mounted on a holder 16 and connected to a hose nipple 6 with a plastic tube 17b. Thereafter, a system communicated to a sample outlet 3 is rendered vacuum making it ready preparations. According to a command from a control section, a proper sample container 15 is selected and a clutch pin 12a is inserted into a pin hole of a gear 10 with a solenoid 13. The rotating force of a motor 8 is transmitted to a gear 9 and a geneva gear 11 through a pin 12b to rotate a rotary base 4 by 1/12 of a turn intermittently. This permits the communication of a sample introduction channel 5 communicated to a specific sample container 15 to one sample introduction path 2 of a fixed base 1 thereby sampling a sample oil from a sample outlet 3. |
