D16 PortaSens Portable Gas Leak Detector

ATi’s D16 PortaSens is a battery powered, hand-held leak detector with an integral 4GB datalogger.

Portable gas detector to monitor, detect and protect

ATi’s D16 PortaSens innovative, versatile, portable gas detector is a handheld monitor designed to perform regular leak checks in gas storage areas, around process equipment, piping, or in confined spaces prior to entry. Using a pump to speed-up gas detection for the protection of people, the D16 also offers alarms and a data logging facility. The superior sensor used in the PortaSens lll is interchangeable between our fixed and portable devices and use an industry-leading, pre-calibrated ‘vapor’ sensor that requires an annual replacement with no calibration, increasing its efficacy. Designed for easy one-hand operation, the gas detector contains an internal sample pump and a flexible sampling wand to allow pinpoint location of the source of leakage. A touch-sensitive color graphic display provides clear concentration display and a back-light for the display ensures readability in low or no light conditions.

A unique feature of the D16 Portasens lll gas detector is its ability to measure a variety of different gases by simply inserting the appropriate sensor for that gas. That makes this gas detector capable of measuring over 60 different gases or vapors, reducing the need to purchase individual detectors for each type of gas. The gas sensors for the detector can be changed quickly and easily, and there is no need for calibration when a gas sensor is change is made.

Advanced Smart Technology 

As one of only a few companies around the globe that manufacture a trusted, smart vapor sensor, used in our industry-leading portable and fixed gas monitors, the gas sensors used in the D16 are part of ATI’s smart gas 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 gas detector, calibration data is loaded into the microprocessor so that no adjustments are needed. The result is that a gas detector can, for example, go from phosgene measurement to ammonia measurement in less than one minute.
