PID Analyzers Laboratory Equipment and Products

About PID Analyzers

PID Analyzers, LLC was formed in April 2003 to acquire the assets of HNU Systems. Inc. (developer of the first commercial photoionization instrumentation). More than 40,000 systems had been sold worldwide between 1973-2003. We still service many of the older instruments such as the PI101, DL101, IS101, PI51, PI51…Our first goal was to develop multifunctional microprocessor based electronics that could be used with virtually any sensor technology for monitoring chemicals. This would be used to expand HNU’s pioneering photoionization technology that was acquired. A second goal was to develop new and/or improved sensors that could be incorporated into our analyzers. We have achieved these goals with the introduction of the Model 102+. The amp board in this analyzer has 5 amplifiers in a compact board. These can be used to process high impedence voltage (microvolts) or currrent (nanoamps), a Wheatstone bridge for combustible gas, capacitance, thermal conductivity, or infrared (microbolometer) sensors, and electrochemical sensors (fuel cell, unbiased and biased).PID Analyzers develops sensors and systems for air, water and process monitoring using technologies such as : photoionization, flame ionization, thermal conductivity, flame photometry, infrared & UV absorption, electrochemistry, capacitance, gas chromatography. Our design expertise is the following areas: • Sensors• GC Detectors• Spectroscopy• Gas Chromatography• Software for systems (C++)- gas chromatographs• Software for controllers (microprocessors) and PLC’s• Instrument packaging including SolidWorks• Electronics & Circuits including intrinsic safety All of our analyzers have proprietary software (operating systems) from the microcontrollers in the Model 102 to the 32 bit C++ software in our embedded software for the Model 301C (PeakWorks™) that runs on Windows XP.We have worked with the US Navy since 1982 to provide portable VOC Analyzers (HNU Model 101, spare parts and service. Now we provide the PID Model 102 VOC Analyzers to the Navy Undersea Systems for all submarines in the US fleet. Our Model 102 has been third party tested and is listed on the National Work Group on Leak detection Evaluations.
