Features
• To measure and take control of indoor air quality
• Three noses in same unit Air Quality (VOC), Humidity (rH) and Temperature (T)
• Selectable outputs 0-10 Vdc, 4-20 mA or 0-5 Vdc via jumpers on pcb for all three measurements.
• Modbus RS485 Network connection, Modbus RTU at 19.2k and 9600 baud
• VOC = Volatile Organic Compounds sensor also named as a mixed gas sensor
• LCD Display show actual value for Air Quality (VOC), Humidity (rH) and Temperature (T)
• Air Quality (VOC) LCD display reading = 0 to 1000 ppm.
0 to 99 ppm = Fine
110 ppm = Fair
400 ppm = Poor
600 ppm = Bad
• Humidity LCD display reading = 0 to 100% rH
• Temperature LCD display reading = 0 to 100°C
