• Fixed photoionization detector (PID)
• Three wire 4-20 mA analog output and RS-485 digital communication in ModBus protocol
• Three dry contact relays (<30V, 2A) normally open (or normally closed), one for High and Low alarm, another for Fault alarm
• Faster response time with sample flow-through design powered by internal diaphragm pump
• Humidity compensation ensures accurate readings even in humid environments
