HD-6A intelligent water activity measuring instrument characteristic: 1. The instrument has been calibrated by the Chinese Academy of Metrology as a reference device for transmission standards. 2. Complies with the latest international standards on water activity (ISO18787:2017 Foodstuff Termination of Water Activity) (which has replaced ISO 21807:2004) 3. Application of new imported sensors to ensure stable and accurate measurements 4. A brand new data processing model ensures accurate measurement across the entire range of the instrument and has extremely high stability in measurement data 5. The measurement time can achieve automatic, timed, manual, and scheduled functions, with extremely flexible and convenient operation methods 6. Historical data can be queried at any time based on sample name or measurement time 7. There are no restrictions on the measured object, and solid, liquid, block, and powder can all be measured The fastest measurement time is only 2 to 3 minutes. Technical parameters: Working environment: Temperature -10 ℃~50 ℃ Humidity 0-95% RH Measurement range: Temperature -10~50 ℃ Water activity 0~1.0000aw Measurement accuracy: Temperature ± 0.30 ℃, Water activity ± 0.0100aw (@ 23 ℃± 5 ℃) Activity repeatability: ≤ 0.0050aw Resolution: Activity: 0.0001aw Temperature: 0.01 ℃ Display mode: 7-inch high-definition display screen resolution: 1280 * 840 pixels Control method: Android system smart screen Endpoint control methods: automatic, timed, manual (can be determined based on measurement curve) Measurement time: ① Automatic determination of end time ② Timing: 5-60 minutes Appointment measurement: Three time slots can be set for automatic measurement of samples Data processing: ① The measurement interface can display measurement data, curves (can display measurement data 0.0001aw changes), and save data
② Automatically save the result data according to the set product name during measurement
③ Data can be queried based on sample name or measurement time and stored in an Excel file Data transmission methods: WIFI, USB flash drive Measurement data can be stored indefinitely Correction methods: multi-point joint correction, single point correction Measurement points: 1 point Power supply voltage: 100-230VAC 50Hz/60Hz Dimensions: 240mm × 210mm × 118mm Power: ＜ 15w
