Active Corrosion Monitoring Unit
AQOZA CORROSENSE Active 2.0 is an advanced device designed to monitor and store real-time data on air corrosivity within indoor environments. This innovative unit provides crucial protection for sensitive electronic components by actively detecting and tracking corrosion rates in the air, enabling timely intervention and maintenance. Using Electrical Resistance (ER) technology, the CORROSENSE Active 2.0 measures metal tracks' electrical resistance to atmospheric conditions, providing precise corrosion rate calculations. Measurements are classified per ANSI/ISA-71.04-2013 (Environmental Conditions for Process Measurement and Control Systems: Airborne Contaminants), giving a reliable, standardised reading of corrosive air conditions for electronics and electrical equipment.
Key Features
- Real-time corrosion monitoring for proactive maintenance.
- Interactive and user-friendly software for easy data access and analysis.
- 5" LCD touchscreen display for convenient on-device monitoring.
- Replaceable copper and silver sensors for detecting specific corrosive agents.
- Replaceable temperature, pressure, and humidity sensors for comprehensive environmental analysis.
- Power input options via Ethernet (PoE) or C-Type Adaptor.
Principle of Operation
The AQOZA CORROSENSE Active 2.0 employs ER technology to directly measure the electrical resistance of exposed and unexposed metal tracks. By calculating the corrosion rate, the device categorizes severity levels according to the ANSI/ISA-71.04 standard:
- G1 - Mild
- G2 - Moderate
- G3 - Harsh
- GX - Severe
The corrosion severity is represented in angstroms for copper and silver sensors, with real-time measurements allowing for predictive maintenance and enhanced equipment reliability.
Benefits of Online Corrosion Monitoring
- Detects corrosive gases in real-time to minimize risks.
- Reduces hardware failure rates by providing actionable data on corrosion levels.
- Supports predictive maintenance for air handling and filtration systems.
- Ensures compliance with environmental and operational standards for critical facilities.
ANSI/ISA-71.04 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 Corrosense Passive v2.0 is a compact and reliable corrosion monitoring device designed to measure the corrosion rate of metals in ambient air environments. It uses the Weight Loss (WL) method, which determines the corrosion rate by measuring the weight loss of a metal coupon exposed to the environment over time. This proven, cost-effective technique provides accurate data to evaluate environmental corrosivity levels in accordance with ANSI/ISA-71.04-2013. Coupons are exposed on site for the specified exposure interval (typically 30 days) and then returned to AQOZA’s laboratory for analysis, with a detailed corrosion report issued for the monitored space.
Key Features

- No power supply required.
- Compact and lightweight design — 10 cm × 10 cm × 2 cm, 40 g.
- Copper and silver metal coupons.
- Suitable for long-term exposure studies.
- Humidity and temperature logging.

Copper and Silver Coupon Analysis
Corrosense Passive v2.0 coupons are deployed at the site for the specified exposure interval and then analysed in AQOZA’s laboratory, where the corrosion rate is determined from the measured weight loss of the copper and silver coupons. Severity is classified to ANSI/ISA-71.04-2013 — from G1 (mild) to GX (severe) — and the detailed analysis report gives clients a clear understanding of the corrosion levels in their facility, supporting informed decisions on gas-phase filtration and preventive maintenance. With no power supply required and an optional temperature and humidity logger, Corrosense Passive v2.0 is a cost-effective solution for assessing indoor air corrosivity and safeguarding equipment from corrosion-related damage.
