MDA Scientific Midas single gas detector

Specifications

Product Description:

Midas® is acclaimed for its innovative Chemcassette® range of ultra-agile low ppmtoxic gas monitoring analyzers and our global network of service engineers (24/7, 7 days a week).

Midas® samples can be used at intervals of up to 30 meters (100 feet) and use control technology to automatically adjust the flow rate to ensure error-free gas detection and manipulation. Honeywell Analytics designs and manufactures its exclusive automated production line of improved sensors, guaranteeing unmatched quality and reliability.

The Midas®' compact form factor and easy-to-inspect metal body design make it easy to install in dense, day-to-day complex process environments or space-critical environments. The Midas® comes with a scale of built-in selectable power and communication modes, including 3 built-in relays, 0-22mA analog outputs, Modbus/TCP Ethernet digital outputs, and the new Power over Ethernet (PoE) protocol—a single Ethernet connection for all power, control, and communication devices. The Midas® architecture significantly reduces the cost of PLC and FieldBus system integration.

Midas® is used for the detection of toxic gas, ambient gas, and flammable gas in typical industrial environments through the transmitter platform. Pre-calibrated "plug and play" smart sensors allow for quick and easy sensor replacement without tools and prevent misuse or discarded sensor errors by operators. High-brightness LEDs as well as intuitive graphs display gas readings and alarm levels when displaying interactive menus (combined with password-protected menus for parameterization, detection and calibration).

Midas® is a highly agile and reliable gas detector for toxic gas and flammable gas used in the semiconductor industry and other general industries. With extended sensor calibration cycles, flexible communication modes, and sensor self-diagnostics and automatic flow control, Medias® significantly reduces the operating costs required for gas detection.
