Description

Description

  • Key performance benefit: Measures surface resistance to classify materials as conductive, dissipative, or insulative across a wide range of 10³ to 10¹² ohms, enabling accurate ESD surface verification in controlled environments.
  • Material & construction: Features built-in parallel resistivity probes fitted with conductive rubber for reliable surface contact. Compatible with external probes, including 5 lb disc probes, handheld probe, two-point probe, and concentric ring probes for expanded testing flexibility.
  • Risk reduction/compliance benefit: Enables systematic verification of ESD control surfaces, including workbenches, floors, chairs, carts, clothing, and packaging materials, reducing the risk of undetected non-compliant surfaces within an EPA.
  • Protection level: Measurements performed with external electrodes meet the requirements of ANSI ESD S20.20 and IEC 61340-5-1.
  • Comfort & usability: Automatically selects between 10V and 100V test voltage based on material being tested. The LED display provides immediate pass/fail classification. Stores up to 9,801 readings internally with USB data export and includes report-building software.
  • Safety & compliance assurance: Meets ANSI ESD S20.20 and IEC 61340-5-1 when used with external measuring electrodes.

FAQs

When should the built-in probes be used versus external disc or point probes?

Built-in probes are suitable for quick spot checks on flat, accessible surfaces. External probes, such as the 5 lb disc electrodes, are recommended when formal compliance testing is required, as measurements taken with external electrodes meet ANSI ESD S20.20 and IEC 61340-5-1 standards. Use external probes for documented audits and program verification.

What types of surfaces can the meter reliably test?

The meter is designed to test a broad range of surfaces, including workbenches, floors, chairs, carts, garments, and packaging materials. Any surface requiring ESD classification within your EPA can be evaluated, provided the appropriate probe type is selected for the surface geometry and material being tested.

How does the auto-adjusting voltage feature improve testing accuracy?

Different materials require different test voltages to produce accurate resistance readings. The meter automatically selects between 10V and 100V based on the material being tested, eliminating manual voltage selection and reducing the risk of incorrect readings from applying the wrong test voltage to a given surface type.

How is stored test data accessed and used for compliance reporting?

The meter stores up to 9,801 measurements in internal memory. Data is transferred to a PC via USB using the included software, which allows users to build structured test reports or export readings as CSV files for integration into existing compliance documentation or spreadsheet-based tracking systems.

Does humidity or temperature affect resistance readings, and how does the Transforming Technologies Resistivity Meter account for this?

Surface resistance is sensitive to environmental conditions, particularly relative humidity. The meter includes an integrated temperature and humidity sensor so that environmental conditions are recorded alongside resistance values, providing context for readings and supporting more accurate interpretation during audits or trend analysis.
