Concern over the long term effects of exposure to formaldehyde, particularly in the home, continues to drive legislators to seek to enforce lower and lower exposure limits. A concern level of 0.08 ppm is typical, but even lower levels are being considered. These two-electrode diffusion sensors for environmental monitoring are based on conventional breath alcohol sensor technology. They do not require a pumped sample (although some users prefer to operate them in that way). The formaldehyde sensor is available in four versions:

"PCB connector" refers to the small PCB attached to the front of the sensor. If it is not included, the connector will be the platinum wires that are embedded in the case. The coloured leads and Molex connector will be included if you also purchase one of our interface boards.

For direct attachment to a circuit board, choose wire contacts. For off-the-board connection, choose the miniature pcb attachment. The premium sensor has a higher catalyst loading and can therefore cope with higher formaldehyde levels.

We offer a calibration service for our formaldehyde sensors using our state of the art laboratory. Currently this costs £15 per sensor - if you would like this service added to your order, please note it in the "additional info" box on the quotation form.
