The Midas S2 is a fixed, extractive single-point gas transmitter that draws a sample locally or from a remote point to a sensor cartridge.
A range of gas sensor cartridges is available to detect toxic, flammable, and oxygen gases used or generated in semiconductor manufacturing, light manufacturing, and research labs specialising in semiconductor processing.
Clear Visibility
Improved graphics display interface for better visibility, instrument status icons, monitoring point and location, and instant gas readings or alarm level alerts.
Calibration Completed
Factory-calibrated sensors reduce the need for frequent gas testing
Improved Serviceability
Easy access to change the sensor and pump from the front of the equipment.
Easy Installation
Compact in size, making it suitable for crowded, complex process environments where space is at a premium, the Midas S2 is simple to install with its plug-and-play capability.
PoE Protocol
The detector includes the innovative Power over Ethernet (PoE) protocol — a single connection for all power, control and communication requirements.
Integrated Security
The Midas S2 interface includes password-protected menus to maintain system integrity.
Features & Benefits
- Highly modular design for easy, reliable, and trouble-free installation.
- Quick replacement of cartridges and pump parts for simple maintenance.
- Single sensor cartridge with onboard ‘e-calibration’ certificate.
- Supportive digital communication (Modbus/TCP Ethernet/Power over Ethernet (PoE)).
- Factory-calibrated sensors to reduce the need for frequent gas testing.
- Large, bright, and rich TFT colour LCD and extensive viewing angle.
- mA communication protocols for easy connectivity and service interaction.
- Robust extractive pump system (2-year lifetime) sampling up to 100 feet.
- Block test to ensure sampling line connection and no leakage.
