| Humidity Temperature Data Logger (HygroLog HL-NT) |
| Manufacturer: Rotronic |
| |
|
Product Overview
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 Software
|
|
|
The ROTRONIC HW4 software (version 2.3.0 or higher) is available in the following versions:
|
HW4 Standard Edition: for single users
- Unlimited number of instruments (depends on capabilities of PC and available ports)
- On-line display of the measured and calculated values (dew point or other) - limited to a single instrument at a time (instrument may have several probes)
- Automatic retention of the most recent data in a temporary on-line buffer
- Logging of measured and calculated values to the PC (can be done simultaneously with local data logging)
- Easy-to-read graphs and data tables
- Statistical data analysis: mean, standard deviation, minimum and maximum (off-line data only)
- Data print-out (table or graph)
- Automatic device / instrument recognition and identification
- Device/instrument configuration
- Adjustment / calibration of the HygroClip and HygroClip 2 digital probes
- Psychrometric Conversion Tool
- Built-in security to protect against manipulation of recorded data
HW4 Professional Edition: meets the requirements of FDA 21CFR Part II / GAMP and allows multiple users, with either administrator or standard rights. On each single port (RS-232, USB or TCP/IP), HW4 Professional can monitor up to 64 instruments connected together in a multi-dropped RS-485 network. The number of such networks depends on the number of available ports.
- All the functionality of HW4 Standard Edition
- Password protected log-in
- User Event Logging: automatically keeps track of user activity
- On-line display in a single graph of the data from multiple instruments and probes
- Overlaying of multiple log files into a single graph
- Self Event Logging: automatically records eventual software problems to facilitate troubleshooting
- Logger Event Logging: automatically records the data logger internal events and configuration changes
- Automatic creation of protocols detailing instrument configuration changes, log function programming and probe adjustment
- Extensive alarm functions and alarm reporting. Indication on the PC of an alarm condition, printing of a report or sending an e-mail (MAPI or SMTP)
- Automatic downloading and archiving on the PC of the files recorded locally by a data logger
- Automatic synchronization of the networked devices with the PC time
- Device protection against unauthorized configuration / programming changes
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).
