T85/T85+
T85 and T85+ Double Beam Spectrophotometers.
T85/T85+
The T85, with a similar product identity to the T65, is a true Double Beam UV Visible Spectrophotometer with a wavelength range of 190 – 1100nm and a fixed Bandpass of 1.8nm (T85) ORa variable Bandpass of 0.5, 1.0, 2.0 and 4.0nm (T85+). The system is fully controlled via a large 10 inch Touch Screen and is fully compliant with CFR21 Part 11.
PRODUCT DESCRIPTION
T85 Double Beam Spectrophotometer has wavelength range of 190 – 1100nm with either a fixed 1.8nm bandpass (T85) or with a variable bandpass of o.5, 1.0, 2.0 and 4nm (T85+). The instrument is supplied with an 8 cell motorized cell changer as standard. The T85 and T85+ are full controlled via a large (10 inch) touch screen.
PG Instruments also have a NEW Computer or PC Tablet controlled software package designed specification for the T65 and T85 UV Visible Spectrophotometer range namely SPA-Win which operates with the latest versions of Microsoft Windows.
