YieldMaster: Simultaneous measurement of CH4 concentration and volume.
The BMP (biomethane potential) test system „Yieldmaster“ is a sophisticated and modular analysis system. In its basic setup it consists of a gas bottle connected via tubing to BlueVCount, precision gas volume measurement device. It measures up to 80ml/min with a resolution of 1ml and consists of a volume measurement cell as well as temperature and pressure sensor.
