Characteristics of HD-5 type

• The instrument has been tested by a certification body and obtained China National Accreditation Service for Conformity Assessment (CNAS) and CMA metrological certification（CMA）TheInternational Mutual Recognition AgreementRecognition of ilac MRA. China recognizes, international mutual recognition.
  

• useWaterproof keyboardIt eliminates the problem of instrument instability caused by contamination such as oil stains and dust on touch keys

• The application of new imported sensors ensures stability and reliability across the entire range

• The instrument has been calibrated by calibration equipment (the benchmark has been tested by the metrology bureau) to ensure the accuracy of the instrument measurementThe multi-point joint calibration method improves the measurement accuracy of the instrument across the entire range

• Specialized software can display and save measurement process data, measurement curves, sample names, measurement results, measurement times, and other data. It can also perform parameter settings, reading, and other operations on the instrument. Specialized software makes operations more convenient and data accumulation and analysis easier.

• It can record 5000 sets of measurement data and transmit them to a computer for storage.
  

• Configure RS232 data interface, USB interface, and micro printer.
  

• Reasonable Chinese interface, easy to operate

• There are no restrictions on the measured substance, and solid, liquid, block, and powder can all be measured

• The needle printer records and can store data for a long time.

• Measurement time 5-40 minutes

• After the measurement and calibration are completed, there will be a buzzing prompt
  

• Host warranty for 6 years

Usage of water activity meter:

1.install

Install the instrument according to the diagram (the plugs correspond one-to-one and cannot be connected incorrectly)

2.Measure directly with instruments

Crush the object to be tested and place it in a plastic container, then insert it into the sensor and cover the sensor.

Due to the intelligent processing of data, onlyPress the confirm button, and the instrument will automatically perform the measurement. After completion, the measurement results will be displayed and printed (due to the use of a waterproof keyboard, the instrument can work stably and reliably even in the presence of water or oil stains)

Due to the use of a new type of highly stable sensor and the calibration equipment used before leaving the factory, the new instrument can be used directly without calibration.

3.Using computers for measurement

Insert the data cable into the computerUSBOpen the measurement software, click the measurement button, and the instrument will automatically perform the measurement. The display interface will show the measurement process data, measurement curve, sample name, measurement results, environmental parameters, measurement time, and other data. After the measurement is completed, the above data will be automatically savedExcelIn the document
