X-LAS MkI Upgrade

Mô tả

To improve existing X-LAS MkI instruments (produced between 2004 and 2011) for customers, there is an upgrade service available which converts it into a X-LAS MkII with all the benefits of the new version, whilst retaining the original housing and mounting. The upgraded functionality includes digital electronics with an internal microprocessor and flash storage, integral display and keypad. A more powerful LED and the improved internal optics and electronics increase the maximum range to approximately 12 km.

The upgrade includes a GPS receiver for accurate time synchronisation and also includes calibration against the Kipp & Zonen reference instrument.

Contact ngoc@ansgroup.asia for more information.

Advantages of the LAS MkII and upgrade:

It is the only scintillometer currently available with a built-in display and control-pad, for easy configuration and installation. It has internal digital processing to make calculations in-situ, to store data, and show real time results on the built-in display.
No absolute instrument calibration is needed, but a certificate is supplied with each instrument detailing a calibration against the K&Z reference instrument, performed outdoors for 2 weeks.
Fast and continuous measurements over path lengths from 100 m up to 4.5 km.
Low maintenance, no moving parts.
Low power consumption.
Integrated lens heater to avoid freezing of the instrument or condensation on the window, and provide good data in cold environments.
Integral data logging.
Both digital output for direct PC connection, and analogue outputs provided. The serial or analogue outputs can be used for customised logging on external data loggers or networks.
Accurate time synchronised with GPS.
Evation software for downloading and processing flux data, provided free.
Optional meteorological sensor (wind speed, air temperature and pressure sensors) plugs directly in the sensor port.
