SRM Sheet Resistance Meter with Four Point Probe
The SRM-232 Sheet Resistance Meters are low-cost hand-held sheet resistance testing systems that include a meter and a four-point probe for use in measuring the sheet resistance of applied coatings such as conductive paints, EMI coatings, ITO on glass, etc. Applications for the instruments include measuring the sheet resistance of conductive paint on Low Observable Aircraft to verify uniform paint thickness, measuring the sheet resistance of EMI paint applied to computer chassis, measuring the sheet resistance of ITO on glass used in flat panel displays, and measuring many other types of conductive coatings. 127 internal data point storage capability. Light, portable, hand-held design. RS-232 interface for remote data transfer.	Four Models, $2000 USD ea. Call or email for a formal price quotation
