Key Factors to Consider When Choosing an Electrostatic Tester

Choosing an Electrostatic tester requires focusing on core performance and practical applicability. Here are the key factors to consider:

1. Measurement Accuracy & Range

• Accuracy directly determines data reliability, with a typical requirement of ±1% to ±3% full-scale error for professional use.

• Measurement range must match application scenarios: Surface resistance testers usually cover 10⁴–10¹² Ω, while electrostatic voltage testers need 0–100 kV (or higher for industrial environments).

2. Test Method Compatibility

• Select contact or non-contact testing based on the object: contact testing (for conductive/antistatic materials) offers higher accuracy, while non-contact testing (for sensitive or irregular surfaces) avoids damage.

• Confirm support for standard test methods (e.g., IEC 61340, ANSI/ESD S20.20) to meet industry or regulatory requirements.

3. Environmental Adaptability

• Operating temperature and humidity range: Industrial models should withstand 0–50°C and 10%–90% RH (non-condensing) to adapt to workshop fluctuations.

• Anti-interference capability: Resist electromagnetic interference (EMI) from nearby equipment to ensure stable readings in complex environments.

4. Usability & Functionality

• Interface design: Prefer clear digital displays, simple operation buttons, and one-click testing for efficiency.

• Additional functions: Data storage (for traceability), USB/data output (for report generation), and low-battery alerts enhance practicality.

5. Durability & After-Sales Support

• Housing material: Choose impact-resistant, dustproof, and waterproof designs (IP rating ≥ IP54) for long-term use in harsh conditions.

• Brand reliability: Opt for manufacturers with professional after-sales service, calibration support, and warranty (1–2 years as standard).
