Miniature Formaldehyde Sensor Gains World Wide Acceptance in Many Applications

Oct 12 2011

The Dart Sensors Ltd formaldehyde sensor, which has been under continuous improvement over several years, is at the heart of a number of recent product launches, with many more expected soon. Key features include; high sensitivity, low cross-sensitivities (particularly CO), and low sensor baseline offset, permitting continuous measurements down to 0.03 ppm HCHO.

Applications under development or in production include:

i. Handheld monitor
ii. Sub-miniature personal monitor
iii. Free-standing tabletop domestic device
iv. Air cleaner
v. Air conditioning equipment

The sensor is of the diffusion type, and is available in premium (high exposure) or economy versions. It can be specified with a contact pcb (as in the picture), or with wire contacts for direct soldering to the customer’s pcb.
