Application
Tips: Can the transmitter be customized for specific applications?
Yes, the transmitter’s measurement range can be customized to suit specific application needs. For example, a lower range (0-2000ppm) may be ideal for residential air quality monitoring, while a higher range (up to 50000ppm) is better suited for industrial environments or research applications. The ModBus protocol further allows flexible integration with custom monitoring systems.
