Dart Sensors labelled products offered on this web site contain original DS sensor components manufactured at our headquarters in the UK, subject to the full DS Quality System.

They are shipped to China and assembled for us by Shenzhen Prosense Technologies. 

Quality audits are carried out by DS staff as follows.

i. Assembly and calibration processes are audited at the Prosense factory four times a year.

ii. Samples of modules are received monthly and their calibrations checked twice by humidified permeation tube systems, first at the Dart Sensors Shenzhen office, after which they are sent to the UK for further confirmation.
