The Importance of Temperature and humidity recorders in Electrostatic control

Temperature and humidity are core environmental factors affecting the generation, accumulation, and dissipation of static electricity. Temperature and humidity recorders provide data support for electrostatic control through precise monitoring and traceability of environmental parameters, making them indispensable auxiliary tools in electrostatic protection systems. Their importance is reflected in the following key dimensions:

1. Temperature and Humidity Directly Dominate Electrostatic Characteristics

1. Humidity affects electrostatic dissipation efficiency: When relative humidity (RH) is below 40%, air insulation is strong, making it difficult for static electricity to dissipate through water vapor conduction, leading to accumulation on object surfaces (e.g., electronic components, plastic parts). When RH exceeds 60%, air conductivity increases, allowing static electricity to leak quickly and significantly reducing accumulation risks.

2. Temperature exacerbates static generation: Low-temperature environments reduce the surface conductivity of materials. Combined with low humidity, static electricity generated by friction (e.g., between chemical fiber fabrics or conveyor belts) is harder to dissipate, and accumulated voltage can increase severalfold.

2. Providing Accurate Data Support for Electrostatic Control

1. Setting protection thresholds: Long-term monitoring via recorders helps determine safe temperature and humidity ranges for specific scenarios (most electronic workshops recommend RH 45%-60% and temperature 20-25°C). When parameters exceed thresholds, dehumidification/humidification equipment can be linked to adjust conditions, reducing static generation at the source.

2. Tracing causes of electrostatic accidents: In cases of product damage caused by static electricity (e.g., chip breakdown, dust adsorption), historical data from recorders can be used to check for abnormal temperature and humidity at the time of the accident, providing a basis for optimizing protection plans.

3. Ensuring Compliance and Stability of Electrostatic Protection Systems

1. Meeting industry standard requirements: Electrostatic protection standards in electronics, semiconductors, and military industries (e.g., ANSI/ESD S20.20, IEC 61340) mandate recording environmental temperature and humidity. Continuous data from recorders serve as critical evidence for compliance audits.

2. Avoiding over-protection or under-protection: Without data monitoring, "blind humidification" (causing equipment moisture damage or product mildew) or "insufficient humidity" (rendering electrostatic protection ineffective) may occur. Recorders enable precise temperature and humidity control, balancing electrostatic protection with production needs.

4. Adapting to Multi-Scenario Electrostatic Protection Needs

• Electronic workshops/laboratories: Monitor environments for chip and PCB production to prevent electrostatic breakdown of sensitive components.

• Packaging/printing workshops: Control temperature and humidity of films and paper to reduce static-induced adhesion or wrinkling.

• Chemical/dangerous goods warehouses: Low humidity easily triggers electrostatic sparks; recorders paired with explosion-proof humidification equipment reduce explosion risks.
