The EE 01TF volume resistivity tester is used for determination of volume resistivity on conductive and semi-conductive rubber according to ISO 1853, and plastic materials according to ISO 3915.

Removable sample holders allow several specimens to be conditioned in advance for efficient testing. The fixture includes a safety interlock that automatically disconnects the test voltage when the lid is opened. The sample holder and measurement probe are designed to provide defined contact force and area on the specimen. The probe positioning is clearly marked, and a probe holder allows the probe to be conveniently moved aside between measurements.

Example of standards:

• ISO 1853
• ISO 3915
• ASTM D991*

* ASTM D991 is not fully verified yet. For testing according to ASTM D991, see accessories below.

For a complete system you need:
EE 01Base + EE 01TF + EC 14

• The base instrument, EE 01Base:
  It can measure currents down to 10 aA (10 × 10^-17 A), charges down to 1 fC, and resistances up to 10¹⁸ Ω with high stability and accuracy. It is also capable of measuring the largest voltage range up to 200 V with an input impedance exceeding 200 TΩ. All this performance is built into an instrument that operates as simply as a digital multimeter.
• The volume resistivity test fixture, EE 01TF, which includes:
  – 3 sets of test piece holders (EE 01-III.03)
  – Electrode system with a controlled contact force and design required by the standards
  – A safety cage which disconnects the voltage when opened
  – Templates for calibration of resistivity
  – Required cables
• The resistivity software EC 14 controls the electrometer and test fixture for standardized resistivity testing. It provides current–time plots to determine electrification time, tools to verify measurement stability, and optional temperature monitoring using a thermocouple probe.
  
  
  • 
    The EC 14 Resistivity application can perform repeated or scheduled measurements to monitor how resistivity changes over time, for example when the material under test is exposed to temperature variations. Test data can be exported for use in spreadsheet software or LIMS systems.
