Cost efficient infrared emitter for NDIR gas analysis and other infrared measurement applications. With only 250 mW required input power, the emitter is also suitable for mobile - and handheld devices. The membrane of this cmOS based ire source achieves membrane temperatures up to 800 °C with long term stable radiation power and short time constant. For high volume applications such as building air conditioning, automation and others, the JSIR 340 is suitable due to its excellent price/performance ratio. The packaging with reflector is good for measurement distances from 2 cm. The MEMS emitter chip consists of a multilayer hotplate membrane containing a high temperature stable metal C-MOSI layer. The emitter chip is based on a silicon substrate with a back-etched membrane. All thin film processes are performed with standard MEMS processes and cmOS compatible materials. The active C-MOSI resistor layer is protected against aging and environment.

µdox is a multi-parameter hand-held measuring device that determines relevant measured values for checking the water quality. These include pH, redox, total hardness, acid capacity and dissolved oxygen with a resolution of 1 ppb. The measuring device is particularly easy to use and to display and record data from up to eight measuring points. Fast analysis of oxygen in the µ range with response times of t90 or t99 of approx. 13 s or 30 s. Oxygen, pH and redox can be determined in parallel. The sensor systems have integrated transient monitoring. Languages and units of measurement can be parameterized. The handheld measuring device is particularly suitable for measurements on hot and steam boiler systems, in district heating systems and power plants.
