Ultra1000 Series Toxic & Oxygen Deficiency

The Ultra1000 Series is a 24 VDC powered toxic gas detector consists of an interface module in a flame proof instrument enclosure and a 316 Stainless Steel sensor head assembly. The detectors monitors a variety of toxic gases in the parts per million (ppm) range, including: ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen, hydrogen chloride, hydrogen sulfide, nitric oxide, nitrogen dioxide, oxygen deficiency, and sulfur dioxide.

The interface module is microprocessor-based electronic assembly with analog and digital circuitry to process the sensor signal for control, data display and to transmit the signal to a Gas Control Panel or to a PLC. In addition, Ultra1000 Series detector includes warning, alarm, and fault relay contacts that can be used to indicate an alarm or fault condition and Modbus communication
