PID Analyzers, LLC
PID Analyzers, LLC was formed in April 2003 to convert to an LLC. The company name was changed from HNU Systems. Inc. (developer of the first commercial photoionization instrumentation). to PID analyzers. 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, PI51, PI51. PID Analyzers develops sensors & analyzers for air, water and process applications and sells these products worldwide. The sensor technologies include photoionization, infrared, electrochemistry, catalytic combustion, flame ionization, capacitance, thermal conductivity, process gas chromatography. Water quality analyzers have recently beed added such as pH, Conductivity DO, and total VOC`s in water. Many of our analyzers are multifunctional and include multiple technologies.

About Us
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. 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…. Descriptions of our instrumentation are shown on our web site on our product page.
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
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.
Many new analyzers with OLED displays & Datalogging
We have developed more tha 18 new analyzers for detecting VOC,s in air, warer, & soils. We have new water quality analyzers for pH, Conductivity , DO and VOc's.
