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 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, for example, go from phosgene measurement to ammonia measurement in less than one minute.

The C16 PortaSens II is equipped with an RS-232 output which allows stored data to be downloaded to a PC through an interface cable that is supplied with the unit. A software package is included with the unit to facilitate data transfer.

Drawings are in development. Coming Soon.

A Portable Gas Leak Detector for the measurement of ________ (Specify Gas or Gases) shall be provided and utilize smart electrochemical sensor technology. The gas sensors shall be interchangeable, enabling easy changing and switching for up to 30 different gas types or ranges within a gas. Sensors shall contain an embedded memory chip for storage of calibration data and gas type information and be designed to easily insert into the gas detector without the use of tools, being keyed for correct placement into the detectors’ sensor connector socket.

The Gas Leak Detector shall contain an internal sample draw pump and a quick connect/disconnect receptacle for attachment of a 10” flexible Teflon lined extension sampling wand and to be powered internally via a rechargeable Nicad battery with an additional “D” battery to be provided as back-up.

The digital display shall be back-lit graphics liquid crystal (LCD) and indicate; gas type and concentration, unit of measurement, full scale range, caution warning & alarm setpoint and pump trouble alarm. The display shall be programmable via membrane switches located on the front panel and provide the user the ability to select range, change setpoints, apply dampening (averaging), change decimal point, change calibration and program the data logging feature.

An RS-232 output shall be provided to indicate stored gas values for up to 12,000 data points through the on-board data logger and 0-1 VDC for current gas values. The data logger shall be capable of storing gas values every 1, 5, 10, or 15 minutes and be provided with Windows 95, Windows 98, and Windows 2000 compatible software on a CD ROM. An RS-232 cable shall be supplied for connection to a computer.

The Portable Gas Leak Detector is to be the Model C16, PortaSens II manufactured by Analytical Technology, Inc. and is to be provided with; a 10” Teflon lined sampling wand, wall adapter battery charger, spare filters, flow meter, RS-232 output cable and carrying case.
