The foam volume of tooth paste is one of the few quality characteristics being recognisable for the user and has therefore a strong influence on the consumer's decision to buy the tooth paste again or not.
牙膏的泡沫量是消費者判斷牙膏質量好壞的因素之一，也因此很大程度影響著消費者決定是否再次購買。

Investigations of tooth paste foam have shown that the subjective feeling of the cleaning effect of tooth pastes with a high foam volume is bigger than of those with a low foam volume. Beyond this, the tooth paste foam reaches parts in the oral cavity where a conventional tooth brush would not get access to. As a result, the radius of operation of the tooth paste foam increases the higher the foam volume is. Besides the foam strength the speed of the foam development and the foam stability play an important role as well.
對牙膏泡沫的調查顯示，消費者在主觀上會認為泡沫多的牙膏比泡沫少的牙膏的清潔效果好。不僅如此，泡沫還能到達口腔中的某些部位而牙刷一般是不能刷到的。因此，牙膏是讓其能盡可能的產生更大體積的泡沫。并且，泡沫的發泡能力、發泡速度和泡沫的穩定性也很重要。

Common and inaccurate measuring methods for example the droplet method, insertion of air method and shower method cannot provide objective test results with regard to the foam's quality. A reproducible measurement with those methods is not possible, especially the measurement of the parameters foam development and foam decay, due to multiple subjective influences.
一般的不精確的測試方法例如羅氏泡沫法、充氣法和淋浴法，是不能提供客觀的測試數據來評定泡沫性能。用這些方法做測試很難具有重現性，特別是測試過程中的發泡性能和消泡性能，因為有多種主觀因素會引起測試結果誤差。

The SITA foam tester R-2000 and its patented Rotor-Foam-Method measure all data automatically whereby subjective influences caused by the user are excluded. If the device is started once, it is possible to carry out many measurement series without operating the device by the user again
德國SITA泡沫儀R-2000及其專利技術的轉子起泡法可以全自動測得所有數據，完全排除了人手操作的主觀影響。儀器一旦運行，可以不需要操作人員進行任何操作就能獲得多組測試結果。

The SITA foam tester R-2000 carries out reproducible and efficient measurements due to a fully automatic procedure starting with analysis of the sample feeding and the analysis of the foam volume up to the cleaning of the sample reservoir. This is especially beneficial when comparing tooth pastes with each other and for an optimization of the tooth paste's formulation respectively.
德國SITA泡沫儀R-2000從開始的樣品注入到泡沫逐步生成量分析到樣品罐清洗，整個過程都是自動的，因此得到的測試結果是可再現和可靠的。這是非常有利于不同牙膏之間的對比和牙膏各配方的最優化。

In order to simulate realistic operating conditions, the sample can be tempered while measuring. Furthermore, a serial port on the device allows a comfortable and automatic evaluation of the test results in combination with a graphic presentation of data on the computer. The SITA foam tester R-2000 guarantees a fast, efficient and reliable test performance in order to achieve valuable results for research and development tasks as well as for quality control.
為了模擬更真實的運行環境，樣品在測試過程中可作恒溫水浴。更值得一提的是，機器自帶的軟件，可方便自動地計算測試結果，在連接的電腦上繪出圖表。為了研發和質量控制能獲得有價值的數據，德國SITA泡沫儀R-2000確保為您提供了一個快速、有效、可靠的測試方案。
