ANSI/ISA-S71.04 Standard
The ANSI/ISA 71.04 standard is the most widely recognized international guideline for corrosion
monitoring. Developed by the International Society of Automation (ISA), this standard specifies
the types and concentrations of airborne contaminants that cause corrosion, helping
organizations classify their environments and ensure the reliability of sensitive equipment.
AQOZA’s CORROSENSE Active 2.0 offers a reliable, user-friendly solution for industries looking to
monitor and manage indoor air corrosivity effectively. Protect your electronics and maintain
operational efficiency with AQOZA’s state-of-the-art corrosion monitoring technology.
Passive Corrosion Monitoring with Corrosion Coupons
AQOZA ER P01 Corrosion Coupons provide a passive, reliable method for monitoring indoor
corrosivity levels. These advanced corrosion coupons, based on Electrical Resistance (ER)
technology, are designed to assess corrosion passively in sensitive environments. The monitoring
process involves placing corrosion coupons in the field for a period of 30 days. After exposure,
the coupons are returned to AQOZA’s laboratory, where the amount of corrosion on copper and
silver films is measured by analyzing the electrical resistance of both exposed and unexposed
metallic films. This method adheres to the ANSI/ISA-S71.04 international standard for measuring
environmental corrosion levels, ensuring accurate and standardized results.
Key Features
- Advanced ER-based corrosion coupons for precise monitoring.
- Accurate and quick results with minimal user intervention.
- High-quality copper and silver coupon films for monitoring specific corrosive agents.
- Passive monitoring technique suitable for a wide range of environments.
- Easy installation with minimal disturbance to the facility.
Applications:
- Control Rooms: Protect critical control systems from corrosive damage.
- Clean Rooms: Ensure optimal air quality and prevent equipment degradation.
- Rack Rooms and Motor Control Centers: Monitor corrosive levels to maintain equipment
reliability.
- Data Centers: Safeguard sensitive electronics from harmful atmospheric conditions.
- Imaging Clinics and Labs: Preserve high-value equipment in medical and research
environments.
Copper and Silver Coupon Film Analysis
AQOZA’s corrosion coupons are deployed at the site for 30 days and then analyzed in the
laboratory to measure the resistance of field-exposed films. Using ER technology, AQOZA
determines the corrosion rate and provides a detailed analysis report. This report offers
clients a clear understanding of the corrosion levels in their facility, helping them make
informed decisions about air filtration needs and preventive maintenance. AQOZA’s Passive
Corrosion Monitoring is a cost-effective solution for assessing indoor air quality and
safeguarding equipment from corrosion-related damage.
