These circuit boards are intended to assist your development program, providing you with a convenient amplified output from our sensors. They provide output of up to 3.75V with a 9V supply (not included). The sensor and power connections receive Molex crimp housing 50-37-5023 – a 9V battery connector with this housing is supplied with the board, and we will include a suitable quantity of connector leads with housings if sensors are ordered at the same time as the board.
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two product types have been merged as there is no longer a difference between them, and the variable gain resistor has been replaced by a fixed 1M gain instead.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 sensitivity of the sensors will be provided in nA/ppm, this can then be converted to a ppm output by factoring in the 1M gain.
