Formaldehyde Sensor, 11mm

This HCHO formaldehyde sensor is of the two-electrode electrochemical type, operating by the diffusion principle and as such requires no external sampling hardware. In the presence of formaldehyde gas a small direct current is produced; the sensor requires no power supply of its own but this current requires amplification to make it readable using external data collection equipment.

Two electrode design does not require a power source.

Lower detection limit of 30ppb.
