Dwyer GSTC-N-LCD-FC is a Nitrogen Dioxide Transmitter with a drift of <5%, temperature range of -4 - 122°F, and an accuracy of CO: ±2% FS, NO2: ±3% FS. It requires a power supply of 10-36 VDC, 21.6-33 VAC, and operates with a low current draw of 5.7 mA @ 24 VDC. This transmitter features a fast response time (<45s to 90% CO, <25s to 90% NO2), a wide measurement range (CO: 0-500 PPM, NO2: 10 PPM), and an IP64 enclosure rating. The field replaceable electrochemical sensor ensures easy maintenance while the UV resistant glass filled polycarbonate housing offers durability. It provides multiple output signal options including BACnet MS/TP, MODBUS® RTU, or MODBUS® ASCII. With a coverage area of 5000 to 7500 sq ft, it is suitable for various applications. The transmitter allows for zero and span adjustments via pushbutton or BACnet/MODBUS® communication protocol. It comes with a removable terminal block for easy electrical connections and features a resolution of CO: 1 PPM and NO2: 0.1 PPM. The calibration can be done using the A-449 auxiliary display and span gas concentration is field selectable. Suitable for humid environments (15 to 90% RH constant; 0 to 99% RH intermittent) and has a storage temperature range of 32 to 68°F.
