RHC040: Scanning capability, relative humidity control (20-85%) and nitrogen atmosphere

The Relative Humidity Kelvin Probe (RHC) systems are the ideal solution for monitoring samples in a controlled atmosphere for contact potential difference (CPD)/work function (Φ) measurements. The RHC systems have the ability to automatically control the relative humidity within the chamber from 20% to 85% 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.

The RHC030 and RHC040 come with nitrogen atmosphere control with the ability to go down to <1% oxygen within the system.

Latest materials and applications from publications
