FA-stLab type of water activity analyzer

FA-st Lab-type water activity analyzer Origin: France Instrument Description: Water activity is the characterization of foods consisting of water, can use water, or water content of the activity. But we can not put the concept of it and the moisture content of confused. Water activity concept used to describe the chemical composition of food due to the composition and leading to the possibility of strong variations of moisture in foods happen to a particular state. The water activity is used to ensure that an important means of testing chemical stability of food, personal care products microbial stability. Water activity testing will help improve product shelf-life and may cause damage to the notice of microbial origin. Main features: 1) A leak test cavity and a sturdy external structure; 2) sensor and the test chamber temperature uniformity; 3) to maintain a constant temperature; 4) the equilibrium time can be set before the test; 5) has automatic correction function; 6) Mirror pollution information alarm function; 7) automatically generate test results report card; 8) test results are accurate; technical parameters: 1) rapid measurement, all test samples can be completed within one minute; 2) rapid cooling mirror dew point technology; 3) Unique airtight system, independent of the size of the sample cup; 4) powder evaporation control; 5) dynamic measurement of water activity - time; 6) real-time display of water activity versus time curve; and 7) Built 240 x 128 LCD liquid crystal display; 8) optional floppy storage accessories; 9) an optional built-in printer, printing, the surface temperature of the relationship between water activity, sample number and time; 10) user-replaceable sensor, easy maintenance; 11) Instruments automatic calibration; 12) Accuracy: +/- 0.003; 13) measurement modes: online, standard, unstable samples, dynamics and continuous mode; 14) Testing time: Depending on the measuring mode, the fastest can be completed in less than a minute , the longest continuous testing for several days; 15) Precision: Depending on the accuracy of the range measurement mode and an infrared sensor for precision: +/- 0.002 to +/- 0.005; 16) Reproducibility: If the sample for each measurement When the can reaches an equilibrium state of reproducibility: +/- 0.001; 17) measuring range: the water activity of from 0.1 to 1; precision infrared sensor 18), the error is less than 2%; 19) having automatic calibration of the instrument function, with the standard liquid
