Mesa Labs would like to announce that the Challenger product line has been discontinued, effective immediately.
Please note that Mesa will no longer manufacture or take orders for the Challenger as of today, June 15, 2015. We will continue to accept RMA submissions on the Challenger until July 1, 2016. After this point, we will no longer perform service or calibration on this product. To obtain an RMA for calibration or service, please visit our website: http:bgi.mesalabs.com/request-an-rma-2/
As a replacement for the Challenger, we recommend the Defender for the calibration of industrial hygiene sampling pumps. More information on the Defender series can be found on our website: http://drycal.mesalabs.com/defender-series/
