GPS to pinpoint your data The LCi T is fitted with a GPS unit to record the exact position of every measurement taken when outdoors.
Latitude, longitude and altitude data are all recorded, displayed on a GPS menu screen, and integrated into the data file for review upon download of data.

GPS to Pinpoint your data The LCPro T is fitted with a GPS unit to automatically record the exact position of each sampling location.
For all measurements taken outside: Latitude, longitude, UTC(Coordinated Universal Time) and GPS alt (altitude) are displayed on screen within 30 seconds of obtaining a signal
