The HygroLog HL-NT humidity, dew point and temperature data logger can be used with any of the HygroClip 2 probes. The HL-NT can monitor up to 7 probes as well as up to two external on/off contacts, such a a door contact.
When used together with the validated ROTRONIC HW4 software the HygroLog HL-NT data logger complies with FDA 21 CFR part 11 regarding electronic data records and electronic signatures (ERES).
The HW4 software can display the data from several data loggers on multiple PCs and can centrally record on one of the PCs the measurement data from several loggers. As a protection against power outages and network failures, HW4 can be used to automatically download the locally recorded data at regular intervals of time.

HW4 Professional with OPC Server: this version includes all features of HW4 Professional while also providing OPC tags that can be enabled for each individual device communicating with HW4. This allows exporting and integrating the HW4 data with with practically any OPC client (requires configuration / programming of the OPC client by the user).
HW4 Validated: this version offers the same functionality as HW4 Professional with OPC server. Additionally, the “HW4 e-compliance Package” is available. This extensive collection of documents (including template of qualification documents) is designed to support the “regulated user” by qualifying/validating HW4-based solutions. The most current validated release of HW4 is v 2.3.0.
HW4 Professional Trial Version: this is a fully functional version of HW4 Professional, including the OPC server functionality. A compressed installation file (zip) can be downloaded free of charge from the ROTRONIC website (click on "DOWNLOADS" in this page header)
Activation requires a product key which can be requested by filling a form on the ROTRONIC web site. A trial product key will be sent to your e-mail address. This must be entered in the registration form which appears when starting HW4 for the first time. After 30 days, the trial product key expires and HW4 can no longer be started.
HW4 Requirements (version 2.3.0 or higher):
Computer/Operating System Requirements:
The following are the minimum values required to install and run HW4 on a computer. It is highly recommended to exceed these values.
Processor: Pentium II, 450 MHz
RAM: 128 MB
Available hard disk space: 50 MB
Monitor: SVGA, 1024 x 768, 256 colors
Ports: one free serial (COM) port or one free USB port or Network Interface Card (Ethernet)
Operating System Compatibility:
Windows XP, NT4 with SP 6a or higher, Vista
Windows 2000 with SP 2 or higher
Windows Server 2003
HW4 v 2.3.0 or higher was written for the Microsoft .NET framework v 2 and requires this framework to be installed on the computer. The .NET framework offers significant improvements in the areas of networking and user security. When new software is being installed, the .NET framework also eliminates the potential problem of conflicting dynamic library files (DLL).
