1. MET-LINK INTRODUCTION
Thanks for purchasing the new MET-LINK wireless for the Gill Maximet line of weather
sensors.
What is MET-LINK?
The MET-LINK handheld solution is comprised of a Gill Maximet sensor, a MET-LINK
wireless interface and a MET-LINK Android Application for your Bluetooth-enabled
Android device.
This new development allows the user to pair the Gill Maximet’s weather sensor
parameters to a useful and full featured tablet and phone application. The MET-LINK
system can be ordered with a GMX-500 with GPS option, GMX-300 or GMX-200. The
MET-LINK compact wind sensors have all the features of the Maximet Gill sensors but
are purpose built to minimize power demand and cost.
Simple to operate, upgradeable, and can be customized with a wide range of
accessories, MET-LINK is a compact field instrument. The sensor is connected to the
wireless module for quick field or process reading. Logged records can be exported
directly from the Android Application to email, Drobox or any number of data
destinations.
The MET-LINK interface module provides rechargeable power to the sensor and
manages wireless communication to a Bluetooth enabled Android device. Sensor can
be powered for up to 5 hours. The module is lightweight, compact, and can be attached
to a tripod.
The MET-LINK Android smartphone application has a large range of features that
support data visualization, data logging, and data management. Data can be viewed
locally (on device) or exported in excel format via Bluetooth, email or GPRS to external
data servers. Logged data is time/date stamped and location tagged for mapping.
MET-LINK can be customized and is upgradeable. The MET-LINK handheld solution
offers un-paralleled ease of use, accuracy, and a very competitive price.
Download the APP today and run in DEMO mode to become instantly familiar with
intuitive operations.
