Relative Humidity Kelvin Probe (RHC) system. Relative humidity system model: RHC020 with 3-axis scanning. The RHC systems are the ideal solution for monitoring samples in a controlled atmosphere for contact potential difference (CPD)/work function (Φ) measurements. Our RHC systems can automatically control the relative humidity within the chamber from 20% to 90% using the easily programmable software. As well as RH control, the RHC020 and RHC040 Kelvin Probe systems come with the KP Technology Scanning Kelvin Probe platform, perfect for plotting the effect of corrosion over the surface of a sample and providing more insight into corrosion protection and resistance. System Specifications: Tip material / diameter: 2 mm stainless steel tip Work function resolution: 1 - 3 meV Sample scanning: 50 x 50 mm Relative humidity control: Automatic: 10 - 95% Measurement environment: Relative Humidity only Optical system: Colour Camera Oscilloscope: Digital TFT oscilloscope for real time signal Test sample: Au / Al Reference sample Breadboard footprint: 900 mm x 600 mm Chamber Dimensions: 400 mm x 400 mm x 500 mm (80 litres) Control supplied: PC with dedicated software Detection system: Off-null with parasitic capacity rejection Warranty: 12 Months
The surface photovoltage spectroscopy modules are the perfect all-in-one solution for in-depth studies of light sensitive materials such as organic semiconductors, solar cells or light sensitive dyes. The modules offer a comprehensive range of measurement modes including DC and AC surface photovoltage studies utilising the built-in optical chopper. Total digital control of all parameters including light intensity and wavelength (400 - 700 nm: SPS030 or 400 - 1000 nm: SPS040) gives the opportunity to investigate and characterise the surface photovoltage and surface photovoltage spectroscopy properties of samples. The latest materials and applications highlighted in published papers includes, gold films, perovskite solar cells, titanium dioxide nanotubes, dye sensitised solar cells, hybrid organic/inorganic photocathodes and tungsten trioxide. Download the product brochure for more information on the Surface Photovoltage range, including technical specifications, example measurements and add-on options. - SPS030 - SPS040 - SPV020
