Modular equipments for technical training at engines under realistic operating conditions: under load at the engine dynamometer. Applications depending on scope of delivery: torque, power = f(speed), specific consumption sfc = f(speed, power) (gravimetric, selectable automatically). Above tests can be carried out in different ways: conventionally or supported by the test bed's MP Computer or with automatic documentation by directly printing or by PC thermal balance (PC required), real function of a transmission (automatic transmission only with PC), p-V-diagram (PC required). Functions of engine and engine control depending on the load may be demonstrated by using motor analysers, exhaust gas analysers and further measuring instruments. Model-specific error-switch boards are extending the demonstration varieties and are enabling a practical error diagnostics. Comparison of different engines under a certain aspect within one lesson.

Analysing the gas quality in the gas network is essential to monitor technical specifications and ensure correct billing.

BlueVary is a maintenance free gas analyzer for variable biotechnological applications. By selectable sensor cartridges different measuring tasks ranging from microbial, cell culture to monitoring of algae and biogas processes can be covered by just one device. The analyzer consists of a basis element with measurement places for two of the variable sensor cartridges. The third place holds a cartridge to compensate pressure and/or humidity. The integrated display ensures an overview about sensor and concentrations at any time. As already known from the forerunner analyzers BlueVary can be mounted on each fermenter from lab to production scale by using different mechanical connections without being limited by fermenter brand or manufacturer. Various data outputs are available. Annual maintenance is not necessary. In combination with the open software BlueVis the BlueVary turns into a versatile, effective tool for real-time online monitoring and optimization of bioprocesses of any kind.

Oxygen is essential for life. Measuring oxygen concentrations plays a central role in controlling biotechnological processes . No matter if fermentations, scale-up studies, bioproductions in lab or industrial scale, the BCP-O2 sensor determines the oxygen concentration in realtime (real time monitoring) in a very convenient way. By measuring the oxygen concentrations oxygen limitations can be avoided and conclusions to metabolic activity can be drawn. With the help of measuring the oxygen important process parameters as OTR oxygen transfer rate or respiratory quotient RQ can be determined. Using BCP-O2 simplifies process optimization in bioprocessing and makes it efficient and precise. In contrast to other sensors the BCP-O2 has in integrated automated temperature and pressure compensation and can be connected to each and every fermenter type. BCP-O2 doesn´t need a minimum flow rate and thus can be applied from small (lab) scale (e.g shake flask) up to the large industrial scale.
