Humidity and temperature affect resistivity so they must be tested. The MTR-1000 tests resisitivity, humidity and temperature of all conductive, antistatic and static dissipative surfaces.
The PFR-153 Floor Resistance Test Kit
was designed exclusively by PROSTAT for measuring resistance of
flooring in accordance with ESD Association Specifications.
Complete test kit contains everything
necessary for testing to ESD S4.1-1997. Includes rigid carrying
case, 2 five pound weights, electrodes and leads.
