Water activity meter

Notă: Because the data has been intelligently processed, so just press the confirm key, the instrument automatically measures, after the end of the display and print the measurement results (because of the use of waterproof keyboard even if there is water, oil stains the instrument can also be stable and reliable work) due to the use of a new high stability sensor, And the calibration equipment has been used before the factory (the accuracy of the calibration equipment can be traced to the National Bureau of Metrology) for calibration, so the new instrument can be used directly without calibration.

Water activity meter

Product characteristics
1. Products comply with GB/T17626, GB/T6587, GB2423 and other national standards
2, excellent measurement accuracy
3. Fast measurement speed, the fastest only 10 minute
4, intelligent software, automatic compensation of environmental parameters
5. The instrument is strictly calibrated
6. Imported high-precision sensor, long service life, precizie ridicata
7. Use the actual weight measurement precision WABun limited material water activity value, using the appropriate sample solution correction
8. It can be measured continuously when measuring different samples without recalibrating or placing the sensor for a few minutes
9. The measured object is unlimited, solid, lichid, lump, powder can be measured
10, the use of self-sealing structure, to avoid the rotary seal caused by the rolover problem
11, LCD Chinese character display, so that the operation process is more intuitive
12, Chinese menu, usor de operat
13, printer output, conducive to saving data, to ensure that the measurement results will not be lost
