Free logging software for PID Analyzer’s Portable Instruments

The free software for the PID Analyzers portables is an easy to use graphing and data log extraction package. It connects to the PID Instrument through a serial (RS232/485) line and reads the data in the data log for rapid display, export, or long term graphing. The data log, and set logging timers and triggers can also be fully configured. The software runs on Microsoft Windows 2000, XP, Vista, 7, or Mac OS X 10.4+ (Intel only) (Universal Binary v3.3.0.2 -

This free software will connect the new PID Analyzers portables and remote PC wirelessly through the new free Bluetooth connection. Of course, older PID portables can also be modified for bluetooth connectivity. See our website http://www.hnu/com. The portable analyzers can be interfaced through the internal RS232 connection or through a TCIP connection that could be controlled with Windows Remote Desktop. The hardware and wireless connections to the PID Analyzers portable analyzers are many fold and very easy to use.

Five channels can be monitored simultaneously with the Model 102+ and only one for the Model 102. The time for the chart can be varied from 1 minute to one year. The data can be saved as a CSV file in Excel format and printed later from Excel like the plot below:

The graph can also be printed or saved as a png or pdf file. The control screen for graphing the five channels of data is shown below:

The second control for graphing is shown below:

The Photoionization detector (PID) in the Model 102 has the fastest response of any on the market with a 90% response time of 1 second. This can be displayed in the live view chart of the Datalogging software by selecting a 1 minute rolling display for recording rapidly responding systems. The portables also have one analog (0-1 VDC) output that is selected by the display. This feature is not available on most portable instruments sold today.Contact us at

Free Bluetooth Wireless Capability for all PID Analyzers Portable Instruments

We recently added bluetooth capability to our Model 102 portable photoionization analyzer . This wireless capability links the datalogging in the 102 with the free logging software in the external PC to produce 1 to 5 graphs (PID ppm/ppb and three other channels selecte from one [IR(CO2, CG or TCD)/TCD/or CG and two other electrochemical sensors (select from > 30 EC Sensors). A typlical plot of PID VOC's ppb and ppb is shown below:
The data is logged into an EXCEL compatable file that is saves in CSV format for opening directly into EXCEL. The format is shown below:
The portable analyzers include the following:

Model 102 PID (only)
Model 102+ PID with multisensor capability and ppb option
Model 113 O2 and other electrochemical sensors (choose from 30)
Model 107 stack gas analyzer
Model 113 with TCD or CG + EC sensors
Model 114 IR + with CO2 or CH4 sensor plus 2 EC sensors

We are offering free bluetooth capability for all new portable analyzers. Contact us at and check out our blogs: &

Can I still get my old HNU PI101 fixed?

That was a common question at the AICHE (#AIHA) show in Portland, OR (May 14-20, 2010). We, PID Analyzers, LLC, brought one of the first PI101's (1st portable photoionization analyzer) ever built to the show. I had many people who stopped, looked at the PI101 and said "I used one many years ago but I didn't realize  that you still made them". I said that we stopped making them about ten years ago but we can still fix them,  Several people asked about an 11.7 probe for their 101 and I said "we can still supply one". I even had one industrial hygienist who stopped by who said " I bought my PI101 25 years ago and it still works. I said "you should send it in for a clean and cal, it will probably need one after 25 years".

Some of our competitors build their PID's like cell phones. That is, their lifetime is just over 2 years and spare parts are available only for several years beyond that. We can fix PI101's that were built 35 years ago. The PI101 was the first portable analyzer that was used extensively in reducing exposure to vinyl chloride, solving exposure problems at Love Canal (1st Superfund Site) and written in to the Superfind legislation. Note that Superfund was "the world's largest industrial hygiene program". That is all history now but the PI101 is still around and can still be fixed 35 years later. For more information click here

A photo of the PI101 with its successor, the Model DL102, is shown in the photo below:
