Kit contains a formaldehyde sensor, interface board and connector wire.
Our formaldehyde interface circuit boards (3-CBF) have been altered from the specification as listed on the datasheet.
The two product types have been merged as there is no longer a difference between them, and the variable gain resistor has been replaced by a fixed 1M gain instead.
This is to allow our customers to use a board with multiple calibrated sensors.
The calibrated version is currently unavailable.
