ml4106

The ml4106 radio transmitter is one of a new range of advanced temperature and humidity radio transmitters. They allow wire-free monitoring of a site, with real time alarm notification and historical analysis of data. Each ml4106 unit reads its on-board sensors to provide accurate and reliable information about environmental conditions. This data is transmitted, at user-defined intervals, to the Radiolog for Museums system where it is filed for analysis.

The ml4106 has two sensors as standard: a precision temperature probe and a high quality humidity probe. These sensors can be mounted internally to the transmitter body, externally on the case or remotely on a probe. An additional surface temperature probe can be added to check the dewpoint margins. These sensors can be calibrated by the users or at Hanwell’s in-house calibration laboratory.

The ID number and transmission rate are set in the ml4106 using a simple software program (free to download) and a USB cable. Each unit has an LCD screen simultaneously displaying the most recent readings taken and the predicted battery life.

The ml4106 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 transmission rate set. An indicator on the LCD will warn when the battery is low, and the ml-4106 maintains a record of when the battery was last changed.

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 more discreet monitoring of public areas is desired.

The ml-4000 range has been designed to comply with the RoHS and WEEE EU directives, and carries the CE mark
