Graphtec Corporation in Japan have recently advised the discontinuation of the WR300 and WR310 Thermal Arraycorder and various optional accessories. Consumables such as thermal paper will be available for the foreseeable future.

Graphtec Service will continue offering support for repairs as per Graphtec's manufacturing commitments.

Although there is no fully compatible replacement for the WR300 and WR310, the Graphtec GL900 or the GL7000 series will be suitable for many applications.
