| H2scan launches next generation hydrogen sensors H2scan Corporation announced the launch of two new hydrogen specific sensor products, the HY-OPTIMA handheld model 500 and the HY-ALERTA in-line model 700. These next generation sensors provide accurate real time measures in extreme conditions, including condensed water environments, the presence of CO and sulfur, and in process streams up to 125șC. The new products are based on H2scan's proprietary 'chip on a flex' technology. Solid state and originally developed by Sandia National Laboratories, the sensing element of both models 500 and 700 is state of the art. It utilizes a palladium nickel capacitor for lower threshold measurements to 15PPM and a palladium nickel resistor for measurements from 5000PPM to 100%. A nickel temperature sensor allows the in-line model to operate in process streams up to 125șC. The new product line also has a membrane and coating over the sensor die that allows hydrogen to penetrate, but keeps all moisture, CO, Sulfur and other gases from penetrating to the sensor die. Like the models it replace - H2scan's Portable Hand Held and 11320019 In-line Real-Time Process Monitor - the HY-OPTIMA 500 AND HY-ALERTA 700 accurately monitor H2 levels against virtually any background gases without the need for expensive support equipment, and can operate in the absence of oxygen and in a wide-range of ambient temperatures. write your comments about the article :: © 2006 Construction News :: home page |
