Toxic Gas Detectors
Protect your team from the invisible dangers of toxic gas exposure with New Cosmos Electric’s high-precision toxic gas detectors.
These portable devices are designed to detect harmful gases such as carbon monoxide, hydrogen sulfide, arsine, phosphine, silane, diborane, and hydrogen — offering accurate, real-time monitoring and early warning alarms.
Whether used for confined space entry, semiconductor manufacturing, or industrial site inspections, New Cosmos Electric’s detectors are built for performance and safety.

XPS-7II
A compact, portable gas detector specifically designed for the semiconductor industry. The XPS-7II features a replaceable sensor unit that allows detection of a variety of gases with a single device. Known as the world’s smallest portable aspirating detector for NF₃ gas, it is engineered for versatility and ease of maintenance.
- Gases Detected: NF₃ and other semiconductor gases (replaceable sensor)
- Special Feature: User-replaceable sensor units
- Applications: Semiconductor fabs, cleanrooms, electronics manufacturing

XP-703DIII
A semiconductor gas leak detector designed for easy leak pinpointing. As gas concentration rises, the alarm sound transitions from intermittent to continuous, allowing users to locate leaks quickly. One device can handle a wide range of semiconductor process gases, including arsine, phosphine, diborane, silane, and hydrogen.
- Gases Detected: Arsine, Phosphine, Diborane, Silane, Hydrogen
- Detection Method: Leak detection with dynamic sound alarm
- Applications: Semiconductor, and manufacturing facilities, leak location verification

XC-2200
A pocket-sized Carbon Monoxide (CO) meter designed for worker safety in confined spaces and industrial environments. Weighing just 75g and only 22mm thick, the XC-2200 offers 5,000 hours of continuous monitoring with a single AAA battery.
- Gas Detected: Carbon Monoxide (CO)
- Detection Range: 0–500 ppm
- Battery Life: ~5,000 hours
- Applications: Confined spaces, maintenance, industrial safety audits
