Important Facts    
   
   


We have been producing, testing and supporting temperature-humidity loggers for many years.  Our flagship product is the DataWatch Elite humidity logger.

This unique instrument is unmatched by any product of its kind.  It is stable, holds its calibration longer than most humidity measuring devices and is very accurate.  The construction is solid, so you can expect years and years of reliable monitoring.

The DataWatch Elite Humidity logger is the best choice where accuracy and dependability are key requirements.  Best of all, the data is reported into a superior data handling software, DataWatch Elite software.

DataWatch Elite Temperature - Humidity Logger

The DataWatch Elite Humidity & Temperature Recorder measures and stores up to 8000 sets of high resolution humidity and temperature readings over 0% to 100% RH & -40C to +70C (-40F to +158F) measurement ranges. 

Using the DataWatch Elite Interface and Data Watch Elite Software, you can control all aspects of performance, including delayed start, sampling interval, number of readings, continuous or fixed number of readings and configuration of conditions to activate the ALERT indicator. Readings are downloaded using Data Watch Elite Software. So, which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as MS Excel.  

The on-instrument display is an informative "extra" that permits a quick review of results in the current recording session.  Screens cycle automatically so that you can recover information without the need to press a button or otherwise interfere with the operation of the unit...this can be important for situations where the unit is inside a case or enclosure designed to control the interior humidity level.

This screen shows the maximum humidity reading after the end (END is shown) of the recording session.  The battery icon indicates a low battery condition.  "HIGH" denotes the high alarm has been exceeded.  The logger icon shows that an alarm conditions has been triggered.
When the logger is set to "wake up" after a specified number of hours (with decimal hours), the display will show the "countdown" to the start time.
In this screen, the average temperature is displayed.  The logger icon indicates the "external temperature" is the subject of the reported data.
Again, here is an "END" display, as notified by the END next to the logger icon.  Shown is the total time that the logger detected an under specification condition.  The time over or under is reported in the units shown...in this instance, the time units are seconds.  No alarm indication is shown, so the time under is less than the alarm criterion.
This is a time indication of an over specification report at the end of the recording session.  A low battery indication is show, as well.  The HIGH alarm is triggered, as the time over exceeds the pre-set alarm setting.

The humidity sensor is protected by a plastic "cage" that prevents accidental touching of the sensitive sensor surface.  Contact us about specialized ways to avoid particulate contamination of the sensor when the DataWatch Elite Humidity Logger is used in dusty or rugged environments.

We supply all units with a prior calibration checkup.  Ask us about our recalibration service.  Recalibration is essential for maintenance of humidity sensing accuracy.   All units are warranted for 24 months. Learn more about DataWatch Elite Advantages.

Specifications  Product Sheet
Temperature Range  -40C to +70C  (-40F to +158F)             
Temperature Resolution  0.1C

Humidity Resolution 0.1% RH
Relative Humidity Accuracy

Humidity is resolved to at least 3% R.H. over the entire range.   Under most circumstances, this reading accuracy will be better.
Humidity and temperature normal operating range   Humidity accuracy is maintained to stated specifications in the Temperature Range specified (above).  We do not recommend usage outside this range, as restoration of normal function may not proceed on a predictable time course.
