| Greetings!
In this August News Edition we're grateful for the beautiful summer weather we've had this month. It almost makes up for our unseasonably rainy June and unpredictable July! We've got some excellent August savings on our Model 102 and 102+ analyzers; I've been busy this month reaching out to current customers and folks that we had quoted hand-held PIDs to in the past to let everyone know about our Trade-In and August analyzer sale. If I missed you, please email me for details put "August PID Sale" in the subject line and of course include your contact details jen@pid.bz.
Attention Global Spec subscribers: Don't miss our Feature Product in the September 10, 2009 Edition of Scientific Instruments Email Newsletter.
Our post-sales service and support contact information is listed at the end of this email. Make sure to email me to receive a discount on the service of your 101 or 102 PID.
We are currently signing Domestic and Foreign Distributors. We are seeking manufacturers reps for our portable & continuous analyzer product line in the following areas: USA 1. Eastern Pennsylvania & S. New Jersey area 2. Chicago area INTERNATIONAL 1. Thailand 2. Australia. The products include continuous VOC analyzers, process gas chromatographs, oxygen analyzers (low ppm to 100%), hydrogen analyzers. Contact Dr. Jack Driscoll at sales@hnu.com.
We began sending out notification emails in June letting you know who your local PID rep is. We will continue to do this as we add new Distributors and Representatives to our team.
We've begun our foray into social media networking: "PID Analyzers for air, water and process monitoring" is on Facebook. |

Low Cost VOC Analyzer
The Model 112 PID can be used for the continuous measurement of the concentration of a wide variety of gases in ambient air, leak detection, industrial environments and related atmospheres.
Typical examples are measurements of:
a. Aliphatic and aromatic hydrocarbons in manufacturing processes b. CS2 plus H2S, NH3, PH3, I2 and other inorganic compounds can be detected by the PID only c. Benzene, ketones and chlorinated hydrocarbons in industrial atmospheres. d. Solvent vapors (chlorinated hydrocarbons) from degreasers, paint spraying operation and various paper and metal coating processes. e. Leaks from process control equipment f. Accelerants (gasoline, kerosene , diesel fuel, lighter fluid...) used to start fires Email jen@pid.bz for a quote. |

Development of Remote Fence line Instruments with Wireless Control for Air & Water Monitoring
J. Driscoll, J. Hamm, and NT Hennigar, PID Analyzers, LLC W. Johnson, P. Perov, P. Hogan, Suffolk Univ., 41 Temple st., Boston, MA 02114
We have developed a line of low power battery powered analyzers for measuring toxic gases and common contaminants in liquids. Typically, these analyzers will operate continuously for 8-24 hours. Since we want to use these same analyzers for fence line or remote monitoring, we need analyzers that will run for extended periods of time (1-6 months) at a chemical plant or at a river or pond. We will be evaluating a number of methods including the following: a "sleep mode" to reduce power and maximize operating time, the remote control of the analyzer ( switching the analyzer on/off) using a wireless mote and finally solar panels to extend battery operation..
The Model 112 PID (8 AH) that analyzes VOCs' in air will run for 20 hours continuously on batteries. We are evaluating an electronic timer for changing the duty cycle to one reading every 5-10 minutes. This will extend the battery lifetime to about one month. The software will be rewritten to collect the sample when the analyzer is turned on. We will also evaluate a remote control using a relay activated by a remote PC and the wireless mote.
For the Model 104 water quality analyzer (pH, T, Dissolved O2 and conductivity), the analyzer will run for > 30 hours (with a 4 AH battery). If we employ a 2.5% duty cycle (one sample every 10 minutes), with this analyzer the operating time will be 1200 hours or 50 days. Remote control and data collection using a relay activated by a remote PC and the wireless mote will be evaluated. This method has many advantages in that it can be returned to near continuous operation if levels above a preset value are encountered.
In a previous paper (1), we ran sensors and preamp only (which required considerably less power than the Model 112 or Model 104 above), and used a larger battery pack with a small solar charging system. We found that system to be less efficient than expected and will present a new more efficient solar charging system for battery operated analyzers. The results of the field testing will be described in this paper.
