The ml4108 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 ml4108 unit reads its
onboard sensors to provide accurate and reliable information about environmental
conditions. This data is transmitted, at user-defined intervals, to the Radiolog
system where it is filed for analysis.
The ml4108 has three sensors as standard: an internal precision temperature probe
a high quality humidity probe and an additional remote surface temperature probe
to check the dew point 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 ml4108 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 ml4108 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 ml4108 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. Suitable for indoor use only.
The ml4000 range has been designed to comply with the RoHS and WEEE EU
directives, and carries the CE mark.
