A Bluetooth module is now on the market to facilitate the downloading of data from the control unit of the Biomass counter. With a special version of the Biomest program and the module, data can be downloaded by wireless connection from the control unit to a palm-top computer. This means it is no longer necessary to interrupt measurements in order to read data; the counter can go on gathering data while the reading is taken. New control units will come with this facility inbuilt; for older ones, a plug with a Bluetooth connection is available.
