from Indiana asked:
January 18, 2016
I'm a little confused as to if this product is just the controller, or if it also includes the sensor for the chemical being tested for? The description reads as if its for the controller only, but it lists it specifically for different chemicals and sensitivity ranges.

Hello Nick, this is only a single channel controller.
