Powder X-ray Diffractometer — APD 2000 PRO by GNR
The APD 2000 PRO is a powder X-ray diffractometer in Theta/Theta geometry with a 160 mm measuring circle. Its 2θ range runs from −5° to 160° (depending on accessories) with angular accuracy better than ±0.02°, driven by a 3 kW X-ray generator. It needs cooling water at a minimum flow of 4 L/min — Two Theta can supply a recirculating chiller alongside it.

Installation
Installation and cooling water
The APD 2000 PRO needs cooling water for the X-ray generator at a minimum flow of 4 L/min and 4–6 bar pressure; maximum power consumption is 10 kVA including the water chiller. Two Theta can supply a recirculating chiller alongside it.
