Pharmaceutical Disinfection Workshop Gas Detection Solution | Nexisense SGA-600 Portable Hydrogen Peroxide / Ozone Detector

In pharmaceutical manufacturing environments, disinfection is an indispensable process. Hydrogen peroxide (H₂O₂), ethylene oxide (EtO), and ozone (O₃) are widely used disinfection gases that effectively eliminate microorganisms and ensure sterile conditions. However, they also introduce potential safety risks. If gas concentrations become uncontrolled or leaks occur, not only may GMP requirements be violated, but the health of operators may also be directly threatened.

The Nexisense SGA-600 series portable gas detector is specifically developed for such scenarios. By integrating high-performance imported sensors with flexible sampling methods and user-friendly design, it helps pharmaceutical enterprises achieve accurate and real-time monitoring of disinfection gases. Whether for routine inspection or emergency troubleshooting, this device provides reliable support.

Common Gas Risks in Pharmaceutical Disinfection Workshops

Hydrogen peroxide is commonly used in VHP (Vaporized Hydrogen Peroxide) disinfection systems to achieve deep sterilization of equipment surfaces and air. However, concentrations exceeding 50 ppm can cause severe irritation to the eyes and respiratory tract and may lead to more serious health issues.

Ethylene oxide is widely used for low-temperature sterilization of medical devices. Although it provides thorough sterilization, it is classified as a Group 1 carcinogen, with extremely low occupational exposure limits (typically below 1 ppm). Any leakage requires immediate response.

Ozone is frequently applied in air purification and localized disinfection. Its strong oxidizing properties make it highly effective, but it also produces irritating odors. Long-term exposure may damage lung tissue.

During gas release processes, pipeline connections, valve seals, or aging equipment may become leakage points. Pharmaceutical workshops are complex in layout, and many areas—such as overhead pipelines, ceiling interlayers, equipment blind spots, and material storage zones—are difficult to cover with fixed monitoring points. Industry statistics indicate that a significant proportion of gas-related incidents are associated with monitoring blind spots or delayed response. Therefore, equipping portable detection devices has become an essential supplement to pharmaceutical safety management.

The Importance of Gas Detection in Pharmaceutical Safety

GMP regulations clearly define requirements for production environment control, including continuous monitoring of hazardous gas concentrations. Timely detection of abnormal levels not only prevents personnel poisoning but also avoids product contamination and batch scrapping, reducing economic losses.

More importantly, a complete monitoring data chain supports incident traceability, process optimization, and compliance audits. Best practice is to adopt a “fixed + portable” monitoring strategy: fixed online detectors provide continuous monitoring of key areas, while portable devices are used for inspections, verification, and blind spot checks.

The Nexisense SGA-600 series is tailored precisely for these needs, supporting dedicated configurations for specific gases, minimizing cross-interference, and ensuring accurate and reliable data.

Nexisense SGA-600 Series Portable Gas Detector Overview

The Nexisense SGA-600 series is positioned for industrial-grade portable applications. Its core sensors are directly imported, offering fast response and excellent repeatability. The device features an ergonomic design, allowing comfortable single-hand operation. After power-on, it enters working status within seconds, without complicated preheating or calibration steps.

Multiple Sampling Methods

Diffusion Mode: Suitable for open areas where gas naturally diffuses into the sensor. This is the simplest operation mode and ideal for rapid scanning.

Pump Suction Mode: An integrated micro-pump actively draws gas samples, suitable for confined spaces, pipeline interiors, or long-distance sampling, providing faster and more accurate response.

Probe Rod Mode: Equipped with an extendable probe rod that can easily reach ceiling spaces, equipment interlayers, or deep shelf areas, making it ideal for pharmaceutical workshop inspections.

Regardless of workshop complexity, users can select an appropriate sampling mode to achieve comprehensive, blind-spot-free coverage.

Key Technical Features

Measurement accuracy reaches ppm or even ppb levels, with ranges covering common disinfection gas safety thresholds. The device maintains stable readings under varying temperature and humidity conditions.

Real-time concentration values are clearly displayed on a high-definition screen. Users can customize multi-level alarm thresholds (audible, visual, and vibration). Once limits are exceeded, alerts are triggered immediately.

A large internal data storage capacity allows continuous recording of thousands of readings. Through a USB interface and dedicated software, data can be easily exported to Excel files or used to generate reports.

Battery life exceeds 8 hours, supporting full-shift operation. USB fast charging is supported. The housing is made of corrosion-resistant and impact-resistant materials, suitable for the humid and chemically exposed environments typical of pharmaceutical workshops.

Typical Application Scenario

After disinfection is completed, operators wear protective equipment and enter the workshop with the SGA-600. Using the probe sampling head, they can extend the detector into overhead pipelines or shelf gaps and obtain residual concentration readings within seconds.

If the values are within safe limits, production can resume smoothly. If alarms are triggered, forced ventilation is initiated immediately and leak sources are investigated. The entire process is efficient and well-controlled.

In real-world projects, this series has been deployed in multiple pharmaceutical plants, vaccine production bases, medical device sterilization workshops, and CDC laboratories. Users consistently report fast response, low false alarm rates, and strong data traceability, significantly improving workshop safety management.

Advantages of Choosing the Nexisense Solution

Compared with general-purpose devices, the Nexisense SGA-600 focuses more on the specific needs of the pharmaceutical industry: dedicated gas sensor configurations, complete probe accessories, and comprehensive data management functions.

The company also provides calibration services, technical training, and rapid-response after-sales support, ensuring long-term stable operation of the equipment. For pharmaceutical enterprises seeking reliable gas monitoring tools, this solution balances performance, convenience, and cost-effectiveness.

Frequently Asked Questions (FAQ)

1. Why must pharmaceutical workshops be equipped with portable gas detectors?
Fixed monitoring has limited coverage, while portable devices flexibly address corners, high locations, and temporary areas, enabling comprehensive inspections.
