PortaSens II Gas Leak Detector from ATI
Description
The PortaSens II has been replaced by the PortaSens III gas detector. The new III uses the same sensors as the II but now has a touch screen.
Designed for easy one hand operation, the PortaSens III gas 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 backlight for the display insures readability in low or no light conditions.
A unique feature of the PortaSens III is it’s 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 are ATI’s 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 go from phosgene measurement to ammonia measurement in less than one minute.
