The conductivity cell 16, as well as the cell itself, are directly connected to each other. riρ) Placed at the top of the order n or placed with one's head down! ! and this causes the reservoir to 12 b The milk flows through them without stopping, υLFI- and the conductivity It is also possible to allow milk to flow directly through the cell and be taken out at the end. 3 are preferably arranged in a looped manner as shown in the tube and cell, thereby The milk sample indicates that the level of incoming milk in tube 13 is below the level of the top of discharge tube 21. in place and therefore enter the cells until the snow between them and fills the cell. and flows through the cell. At this point, a new sample has been introduced into the cell and 1,000 times before extruding the sample until direct exchange or the device drains the sample. The sample remains in the cell 16 until it is tilted so that the sample is exposed. in this way Then, the drinker introduces the milk sample directly into the cell and the milk flows through the cell. No need to take readings at exact points (and perhaps his timing is not good enough) Read at your own pace, so as not to miss the reading due to lack of speed. Easy to get.

For each sample, the level of sample milk in tube 13 was reached. reaches the level of the discharge tube 21, each subsequent milk sample The air bubbles are forced into the conductivity cell prior to purge the sample. Such air bubbles between samples are preferable, but Do not mix in server 12b9 (it is mandatory if it can be introduced into the system) Not in. The above-mentioned distribution system is such that once a single sample is received, It is extremely useful for direct access from the system to the current system, and therefore the sample is Detection of the sample as it flows into the cell, through the cell, and out of the cell results in no mixing or It was found that there was virtually no contamination of the sample.

This eliminates the need to recycle the cells after each use or after each use. This will cause problems between samples, which could cause damage to the cup-shaped conductivity cell if not thoroughly cleaned. Mix and circulate contamination.

Having the same volume of milk in the cell each time a reading is taken will result in an accurate conductivity reading. It is 1 lower to get . For this reason, for each conductivity reading taken, the cell It is best to be completely filled with milk. Operation of the device shown in Figures 1-3 This is the conductivity cell 16, nipples 12c, z and reservoir 1. 2c of the tube 13 leading from the conductivity cell 16 to the conductivity cell 16. This is achieved by increasing the capacity of the server 12b. Thus, Den 4 It has a volume of approximately 2- to 12 Ccp/l/16 - 10,000 reservoirs = 1 to 12 Ccp. Two squirts of milk surround the volume and the opening into the nip/l/12C This gives the iDK foam-free milk a lot more than the standard one. 3 and cell 16.
