Ultra fast water activity measurement of up to 4 product samples simultaneously

• AwQuick Mode - accelerated water activity measurement: the average time required to measure a product sample can be reduced to less than a minute by running 4 probes simultaneously
• Standard Mode: conventional water activity measurement with automatic detection of equilibrium and the option to record / graph the data
• Automatic capture of the end values to a text file to facilitate record keeping. Each record includes product description, probe identification, date and time. Includes 2 sizes of sample holders and disposable sample cups, humidity calibration standards, etc. HygroLab 2 indicator accepts a large choice of probes, suitable for the direct measurement of products in bulk and other applications

Calibration

The digital HygroClip probes can be calibrated and adjusted at one or more points with the HygroLab indicator: • For a quick check of the probe and eventual 1-point adjustment of humidity and temperature, you can plug a   freshly calibrated probe into any free probe input and adjust against this probe. • For scheduled maintenance, you can adjust temperature at up to 2 points and humidity at up to 4 point against   physical references. You may also make use of the full interchangeability of the HygroClip digital probes and rotate the probes with a calibration laboratory. The calibration laboratory can do any of the following:
Use the HygroLab 2 indicator to directly calibrate and adjust the probe Connect the probe to an MOK-03-WIN or B5-03-WIN cable and adjust the probe using a PC on which the HW3 software has been installed
	HW3 Software: software based probe calibration is both simple and precise: there are no hard-to-reach, hard-to-adjust potentiometers. HW3 offers a high level of flexibility in selecting the calibration reference, giving the user complete control over the calibration process. HW3 features the following calibration modes: • Humidity: 2, 3 or 4 points • Temperature: 2 points • 1-point adjustment function (offset) for both humidity and temperature When humidity calibration is done using the ROTRONIC humidity standards, HW3 automatically corrects the value of the standard to reflect the temperature of calibration (see note). HW3 also offers the possibility of printing a certificate of calibration. Note: the value of the standards does not depend on barometric pressure (altitude).
	Certified Humidity Standards: if you do not have access to a humidity generator, the ROTRONIC humidity standards offer a reliable and convenient way to generate a reference humidity condition during probe calibration. The ROTRONIC standards are shipped with an internationally accepted certificate, meeting in full the requirements of quality systems such as ISO9000. The standards are available in boxes of 5 glass ampoules of the same value, and can be stored indefinitely. Standards in the range of 5 to 95 %RH are non-saturated aqueous salt solutions. The 0 %RH humidity standard is made of small granules of a highly porous ceramic. A Material Safety Data Sheet is available for each standard.
	Calibration Devices: some of the probes used with the HygroLab 2 may require a calibration device to hold the humidity standard. This device is a small airtight container that fits on the probe and seals around the humidity sensor. During calibration, a known reference humidity is produced inside the calibration device by means of a humidity standard. Four calibration devices are available for the HygroClip probes: ER-15 for 15mm diameter probes ER-05 for 5mm diameter probes
