This 21CFR-compliant standalone data logger records and displays over 32,000 temperature readings from the supplied high accuracy thermistor probe. The data logger features an LCD and push-button which allow the user to cycle through the most recent, highest and lowest stored readings.
The logger enjoys all of the core offerings of the original EasyLog software, but with additional 21CFR characteristics including user permissions, encrypted data which cannot be edited, full audit trail and electronic signatures for all activity.
Easily set up the logger and view downloaded data by plugging the unit into a PC's USB port. Supplied with 1/2 AA battery and wall mount clip, glycol bottle thermistor probe, long-life lithium battery, traceable calibration certificate and software.
Application Info
The EL-21CFR-TP-LCD+ has been specifically developed to meet the data security required by the FDA's 21CFR part 11 regulations. As such it is suitable for use in applications where the integrity of the data is of the highest importance.
This standalone data logger measures and stores more than 32,000 temperature readings over a -40 to +125°C (-40 to +257°F) range with a resolution of 0.1°C (0.2°F).
The user can easily set up the logger and view downloaded data by plugging the data logger into a PC's USB port and using the free EasyLog 21CFR software. Data can then be graphed, printed and exported to other applications for detailed analysis. The encrypted data has full audit tracking to comply with the requirements of 21CFR Part 11.
The high contrast LCD can show a variety of temperature information. At the touch of a button, the user can cycle between the current, maximum and minimum stored values for temperature.
The data logger is supplied with a lithium metal battery which typically gives two years' logging life.
Calibration
The EL-21CFR-TP-LCD-PROBE-G comes with a calibration certificate issued at 2 and 8°C.
CONTROL YOUR LOGGER
Users can configure their loggers with the following parameters:
- Logger name
- Temperature measurement parameter (°C or °F)
- Logging rate (user selectable between 1 second and 12 hours)
- High and low alarms for temperature
- Immediate and delayed logging mode
- Probe type
Once users have recorded data, the built-in graphing software allows them to graph and annotate their data, or export it to Excel, PDF or jpeg formats.
CONTROL YOUR DATA
EasyLog 21CFR software ensures digital security and compliance:
- Assign individual
- users with specific permissions
- Full software & session data audit trails
- Receive email alerts for failed log in attempts
- Digital signatures added to all reports
- Add comments to specific readings
DISPLAY STATUS INDICATION
The EL-21CFR-TP-LCD+ features a high contrast LCD which shows logged temperature values using seven segment numbers, along with annunciators. The LCD can also show information regarding the loging status.
The LCD shows three different recorded readings, which can be cycled through using the built-in push button. The most recent logged temperature, maximum logged temperature and minimum logged temperature can be displayed.
To increase battery life it is possible, via the software, to turn off the display or have it active only after pressing the button.
LED STATUS INDICATION
The EL-21CFR-TP-LCD+ features two LEDs:
- The first LED flashes red to indicate that the EL-21CFR-TP-LCD+ is in an alarm condition. It will flash when the logged temperature has exceeded a Low or High alarm level.
- The second LED flashes green to indicate that the EL-21CFR-TP-LCD+ is not in an alarm condition.
Using EasyLog 21CFR Software it is possible to set the alarm to remain active even if the reading has returned to normal, in which case the alarm LED will continue to flash red. This 'Hold' feature in the software ensures the user is notified that at some point an alarm level has been exceeded, without needing to download the data.
Hold is enabled by default, and can be turned off via the control software. The red LED will then only flash whilst the logger is in an alarm condition. When the temperature returns to normal, the green LED will flash.
Using the control software it is possible to set a delayed alarm. In this mode the logger has to see multiple consecutive alarms before being activated.
The probes supplied with the EL-21CFR-TP-LCD+ uses a precision thermistor to sense the temperature. Alternative lengths and probe options are available. The probe type is selected in the control software and should match the label on the probe in use.
Alternatively, the probe length may be extended by the use of a suitable extension cable. We recommend twisted pair with high quality 3.5mm jack socket/plugs for best results.
The thermistor is externally isolated from the probe tip.
