Next-level safety: New portable PS DUO from Teledyne GFD detects two gases simultaneously
The new PS DUO uses passive diffusion sensing for the continuous detection of harmful gases in potentially hazardous environments, enhancing safety for personnel. It can monitor two gases simultaneously from a wide selection that includes carbon monoxide (CO), hydrogen sulphide (H₂S), sulphur dioxide (SO₂), ammonia (NH₃), oxygen (O₂), hydrogen (H₂), nitrogen dioxide (NO₂) and ozone (O₃).
Teledyne Gas & Flame Detection (Teledyne GFD) is unveiling its PS DUO, a portable dual- gas detector set to enhance personal safety in gas monitoring applications.
This innovative handheld device features real-time monitoring with audible, visual (bright LED) and vibrating alarms, providing immediate alerts when gas levels exceed safety thresholds.
Users of the ATEX/IECEx-rated PS DUO can select flexible gas pairings according to their specific application. The result? Enhanced safety, flexibility and peace of mind in the field, backed by a 2-year warranty.
For applications in regions such as the Middle East, H₂S/ SO₂ capability will prove especially useful. The PS DUO offers a measuring range for H₂S of 0~100 ppm with 0.1 ppm resolution, while 10 ppm and 15 ppm represent the low alarm and high alarm respectively. For SO₂, users can take advantage of 0~20 ppm measuring range, 0.1 ppm resolution, 2 ppm low alarm and 5 ppm high alarm.
The LCD display provides continuous real-time gas concentration information, while the internal memory supports up to 30 alarm logs. Wireless connectivity allows seamless data retrieval and safety system integration.
Of particular note is the instrument’s rugged, IP67-rated rubberised enclosure, which combines with an ergonomic, compact (56 x 89 x 21mm) and lightweight (200g) design for optimal user comfort, convenience and safety. The PS DUO will operate for up to 2 years on a single replaceable battery under normal use.
“With its reliable performance, flexible gas pairings and wireless integration, our PS DUO offers a powerful new option for industrial safety programmes - backed by Teledyne’s global service and support,” states Pawel KULIK, Product Manager-Portables, Teledyne Gas and Flame Detection. “It adds to an existing and highly successful range of personal safety and gas monitoring solutions that includes our portable Protégé ZM and PS200.”
Available in O2, CO, H2S and SO2 models, the easy-to-use Protégé ZM (Zero Maintenance) single-gas monitor delivers high performance in a small, ergonomically designed package. Offering proven reliability in the field, industrial workers and first responders gain the confidence to focus on the task at hand, not on their equipment.
Teledyne GFD’s PS200 four-gas compliance monitor is compact, lightweight, water resistant and extremely robust. This user- friendly device is a proven performer in hazardous locations with its ability to measure any combination of LEL (Lower Explosive Limit), O₂, CO and H₂S. The PS200 pumped gas detector features an internal sampling pump for optimal use in confined space applications.

Methane detection and monitoring: New MethaSense series from Teledyne GFD covers all applications
With the arrival of new methane emissions standards and legal reporting dates, the detection and monitoring of environmentally damaging gases is the spotlight like never before.
For residential, industrial and utility applications, Teledyne Gas & Flame Detection (Teledyne GFD) is offering vital assistance with its new MethaSense range of battery- powered methane detectors, which allows users to take advantage of cutting-edge NDIR (non-dispersive infrared) sensor technology.
All three models in the versatile, autonomous new product family - MethaSense, MethaSense XP and MethaSense Trace - feature patented NDIR sensors for reliable and precise methane detection. To suit residential and commercial applications, MethaSense is a compact, wireless natural gas detector with a range of 0-5 % volume. High methane selectivity and immunity to sensor poisoning ensure accurate detection without false alarms, making this state-of-the-art detector ideal for preventing gas-related incidents in homes and small businesses. Integrated audible and visual alarms provide immediate alerts to safeguard occupants and property, while its compatibility with advanced metering infrastructure supports smart home integration.
Progressive signal processing algorithms ensure MethaSense detects, alarms and monitors methane at concentrations as low
as 10% of the lower explosive limit (LEL) for enhanced safety. Optional wireless (LoRaWAN) connectivity enables real-time gas detection visualisation, further boosting safety and efficiency with clear, actionable insights.
Offering low cost of ownership, MethaSense delivers both affordable protection and peace of mind. In addition, 10+ years of battery life means MethaSense operates independently for continuous protection, even during power outages.
Also part of the product family is MethaSense XP, which is engineered for industrial environments where robust performance and reliability are essential. MethaSense XP’s rugged design and reliable detection capabilities ensure worker safety and operational continuity, especially in areas where maintenance access is limited.
It combines the same advanced NDIR sensor technology with enhanced durability and wireless communication options, including LoRaWAN, NB-IoT and Bluetooth. MethaSense XP again features audible and visual alarms, while its 10+ year battery autonomy and immunity to corrosion and saturation make the detector ideal for continuous safety monitoring in demanding conditions. With ATEX and IECEx certifications, MethaSense XP operates reliably in hazardous zones.
Completing the family is MethaSense Trace, a high-performance methane detector for
LDAR (leak detection and repair) and utility applications, where accurate and autonomous methane monitoring is essential for regulatory compliance and environmental protection. A rugged build with IP67 ingress protection rating for outdoor use ensure uninterrupted performance in harsh conditions, reducing operational risks and maintenance costs.
Exceptional methane sensitivity provides 10× higher methane selectivity than previous-generation sensors, with a detection range that extends from 50 ppm to 100% volume for both low-emission environmental monitoring and high- concentration safety thresholds.
A fast and comprehensive solution, the detector delivers 24/7 methane emission monitoring, detection and quantification across large-scale industrial sites. By combining real-time sensing, cloud- based analytics and automated reporting, MethaSense Trace enables operators to detect, localise and measure methane emissions with precision. This not only helps reduce emissions but also ensures full compliance with new methane regulations.
As of 5 August 2025, operators in the EU must submit detailed reports on their annual source-level methane emissions in accordance with the EU Methane Regulation (previously
Regulation 2024/1787). The reports need to include comprehensive data on methane emissions from all relevant sources within the facility. Independent verification is also necessary.
“NDIR technology, as utilised by all three detectors in our new MethaSense series, offers high selectivity, fast response times and long-term reliability,” explains Régis PREVOST, Product Line Manager, Teledyne GFD. “Users benefit from natural gas detectors that provide a low-maintenance, cost-effective, versatile solution for continuous methane monitoring, supported by key features that include up to 10+ years of battery life, zero recalibration requirements, wireless connectivity options, and suitability for smart infrastructure and safety-critical environments.”
