•Controlled via Gilson’s UniPoint™ System Software or choose stand-alone keypad control with the 151 and 155 models
•Stores up to 10 detection methods
•Choose from the following modes to specify detection conditions and basic operating parameters: 1.single wavelength
2.file
3.status
4.setup
5.dual wavelength (155 and 156)
6.scan wavelength (155 and 156)

This item has a broken top hinge on the door/control panel as per close up image, though the door can still be closed. It also requires a new Visible Tungsten/Halogen Lamp Assembly (VIS) which is available from Gilson (http://www.gilsonuk.com/catalogue/product/itemNo/100325) the Deuterium Lamp (UV) is starting correctly however so does not appear to need replaceing. With this in mind we are selling for spares/repair only and have priced accordingly.
