Profile: Analytical Technology, Inc. designs, manufactures, and distributes analytical instruments based on electrochemical & optical sensors. We specialize in the areas of toxic gas detection and water quality measurements, & continue to lead the way in the development of reliable monitoring systems. Our capabilities in the area of sensor design and manufacture allow us to offer the kind of application support needed for the most demanding applications. The Series C16 PortaSens II portable gas leak detector, is a versatile tool for performing regular leak checks in gas storage areas, around process equipment and piping, or in confined spaces prior to entry. Designed for easy one-hand operation, the detector contains an internal sample pump, and a flexible sampling wand to allow pinpoint location of the source of leakage. A large character display insures that measured values are easily visible, and a back-light for the display insures readability in low or no light conditions. A unique feature of the C16 detector is its ability to measure a variety of different gases by simply inserting the appropriate sensor for that gas. This means that one detector can be used to measure over 30 different gases or vapors, reducing the need to purchase individual detectors for each type of gas. And sensors can be changed quickly and easily, without the need for calibration when a sensor change is made. Sensors used in the PortaSens II are our newest miniaturized smart sensor modules. Each sensor module is actually a sensor, amplifier, and memory module in one compact package. Because of this design, sensor modules can be calibrated independently, and simply plugged into any detector for immediate use. When installed in a detector, calibration data is loaded into the microprocessor so that no adjustments are needed. The result is that a detector can, for example, go from phosgene measurement to ammonia measurement in less than one minute.
