OUTDOOR TEMPERATURE & HUMIDITY DATALOGGER HANWELL ML4109-OD

The ML4109-OD datalogger is one of a new series of advanced standalone temperature and humidity dataloggers.

 

This ML4109-OD datalogger is suitable for recording temperature, relative and absolute humidity in harsh environment such as inside tombs, caves, outdoor etc. especially when relative humidity reaches 100%.

This datalogger withstands heavy rain, snow, extreme cold, heavy sunlight and UV radiation, all of the above do not affect the recorded measurements.

 

Each ML4109-OD data logger reads its on-board sensors to provide accurate and reliable information about environmental conditions.The logging interval can be set for any period between 10 seconds and 24 hours, depending on the data requirements. An unlimited delay can be set so that logging only begins when the unit is in situ. The readings are written to its 2048K memory, which can either stop logging if it becomes full, or wraparound so that the most recent data is not lost. A unit set to log every 5 minutes will take more than 340 days to fill.

 

The probes are a precision temperature probe and a high quality humidity probe. These probes can be calibrated by the users or at Hanwell’s in-house calibration laboratory.

 

The datalogger is set-up and downloaded using an integrated software package, which automatically recognises the type of unit connected to the PC via the USB lead. Additional software add-ons allow the software to be run with advanced security features.

 

The datalogger is powered by a single 3.6V AA lithium battery, which can be fitted by the user. The battery life will be dependent on the logging interval selected. The datalogger maintains a record of when the battery was last changed. Replacing the battery when the datalogger is connected to the PC allows the logging session to continue uninterrupted.The moulded case allows easy access to the battery and USB socket, as well as having slots to fit onto secure wall brackets and a plain front panel to hide the LCD if desired.

 

The ml4000 range has been designed to comply with the RoHS and WEEE EU directives, and carries the CE mark.
