Indoor corrosion monitoring is a critical technique used to detect and measure corrosion in sensitive electronics, providing an early warning system to prevent costly failures. By continuously tracking corrosion rates, companies can implement the right preventive measures to protect valuable equipment in environments prone to corrosive gases. Early detection of corrosion helps avoid premature failures and extends the service life of electronic systems.
Corrosion in electronics can occur for various reasons. While manufacturing defects, such as residual flux, can cause some corrosion issues, these are typically covered under manufacturer warranties. However, a major cause of corrosion is the infiltration of external pollutants, such as airborne contaminants and gaseous particles, which react with metals in electronics. With the shift toward lead-free electronics under RoHS directives, components are now even more susceptible to corrosion, leading to higher maintenance costs and reduced lifespan if not managed properly.
Aqoza offers comprehensive corrosion monitoring solutions, both active and passive, based on ANSI/ISA-71.04-2013 standards, enabling businesses to identify the rate and severity of corrosion. Our corrosion monitoring services are designed to safeguard critical facilities, including data centers, server rooms, and control rooms, which are vulnerable to contamination from nearby sources such as sewage treatment plants, heavy traffic, open drains, and industrial facilities. Even trace levels of corrosive gases, in parts per billion, can lead to significant damage if left unchecked.
Provides a complete corrosion assessment by exposing sensors over a period of 30 days. This approach offers a comprehensive view of corrosive conditions over time, helping businesses assess long-term corrosion risks.
Delivers real-time data and continuous tracking of corrosion levels, allowing for immediate intervention when necessary. Data is recorded and stored, enabling proactive corrosion management and decision-making.
Aqoza’s corrosion monitoring solutions are designed to protect electronics, minimize maintenance costs, and enhance operational reliability. With our advanced monitoring systems, industries can ensure the safety and longevity of their electronic assets, avoiding unexpected failures and safeguarding productivity.

Data centres and server rooms need corrosion monitoring because corrosive gases attack circuit boards silently — hardware fails before anyone sees a problem. AQOZA measures air corrosivity against ANSI/ISA-71.04-2013, classifying the environment from G1 (mild) to GX (severe) by copper and silver reactivity. Even parts-per-billion levels matter: in a documented hotel server room, monitoring found copper at GX with zero prior visibility.
The corrosive gases that damage indoor electronics usually enter from nearby sources — sewage and wastewater treatment plants, heavy traffic, open drains and industrial facilities. AQOZA corrosion monitoring measures their combined effect directly on copper and silver, the same metals on your boards. Hydrogen sulphide, sulphur dioxide, chlorine and oxides of nitrogen are the main culprits, corrosive even at trace levels.
Passive monitoring uses AQOZA Passive v2.0 copper-and-silver coupons exposed on site for 30 days, then analysed in AQOZA's laboratory — a low-commitment way to establish your ANSI/ISA-71.04 classification. Active monitoring uses the AQOZA CORROSENSE Active 2.0, tracking corrosivity continuously on a touchscreen for real-time intervention. Most facilities start with a 30-day assessment, then add continuous monitoring where the risk is confirmed.
Corrosion monitoring measures how corrosive your air is; corrosion control removes the gases causing it. AQOZA monitoring — CORROSENSE Active 2.0 sensors and 30-day coupons — classifies the environment to ANSI/ISA-71.04. If it reads worse than G1, an AQOZA Corrosion Control Unit filters the corrosive gases at source, while monitoring continues to verify the environment recovers towards G1. Monitoring proves both the problem and the fix.
AQOZA's passive monitoring is well suited to occupied facilities: Passive v2.0 copper and silver coupons are exposed in the room for 30 days, then lab-analysed to classify the environment to ANSI/ISA-71.04. The CORROSENSE Active 2.0 is a compact, self-contained unit that records continuously in the monitored space. Talk to AQOZA about placement for your server room or control room.
Corrosion monitoring supports preventive maintenance by revealing atmospheric corrosion risk before it damages hardware, so teams act on data rather than after a failure. AQOZA's CORROSENSE Active 2.0 records corrosion trends continuously, while 30-day Passive v2.0 coupon assessments benchmark the environment against ANSI/ISA-71.04. Tracking severity over time lets facilities schedule interventions early and avoid unplanned downtime in critical rooms.
Yes — monitoring and control work together. An AQOZA Corrosion Control Unit removes corrosive gases, but only monitoring proves the environment actually reaches and holds ANSI/ISA-71.04 Class G1. AQOZA verifies control performance with CORROSENSE real-time ER sensors and 30-day copper-and-silver coupons, so you can demonstrate protection to auditors or the board rather than assume the filtration is working.
