Overview​​
The SHM-4000 is a state-of-the-art static electricity meter designed to quantify static charge buildup, surface resistivity, and conductivity in textiles, polymers, and industrial materials. Critical for manufacturers of protective clothing, electronics, and flammable material handling systems, this instrument ensures compliance with global safety standards (IEC 61340, ASTM D257, EN 1149) while delivering precise, real-time data to mitigate fire hazards and electrostatic discharge (ESD) risks.

​​Core Features​​

1. ​​Static Charge Measurement​​:

   • Measures static voltage (0–50 kV) and charge decay time (≤5 seconds) to evaluate material propensity for static buildup.
   • Equipped with non-contact electrostatic field meters and ionization chambers for accurate readings.

2. ​​Surface Resistivity Testing​​:

   • Tests surface resistivity (Ω/sq) and volume resistivity (Ω·cm) per ASTM D257 to classify materials as conductive, antistatic, or insulating.
   • Automated calibration for consistent results across diverse material types.

3. ​​Material Compatibility​​:

   • Supports textiles (polyester, nylon), polymers (PVC, rubber), and composites used in ESD-safe workwear, flooring, and packaging.

4. ​​Dynamic Environmental Simulation​​:

   • Adjustable humidity (10–90% RH) and temperature (5–40°C) to replicate real-world storage and operational conditions.

5. ​​Data-Driven Compliance​​:

   • Generates reports with ISO 13400-compliant static decay curves and pass/fail indicators for ESD-sensitive industries.

​​Technological Innovations​​

• ​​AI-Powered Predictive Analytics​​: Machine learning algorithms forecast static-related failures based on material aging tests.
