Investigator’s Aid

For Detection of Hydrocarbons, Accelerants, Petroleum volatiles and various Gases

The Model 950-ASH Arson Scanner and Accelerant Detector is a precision instrument designed specifically for detecting trace levels of hydrocarbons and accelerants.

Model 950-ASH is optimized for detecting hydrocarbons or accelerants that may be present at suspect arson fires.

Model 950-ASH functions as an excellent general purpose discovery instrument for field survey such as: searching landfills for methane outgassing, the detection of leaking underground storage tanks, or simply as a general purpose gas leak detector.

Additionally, Model 950-ASH employs an array of illuminating ultraviolet and white LEDs which further assist the investigator in locating accelerants or other evidence in situations where detection in low visibility environments becomes difficult. Other beneficial features include a Mute function to silence the audible tones for discreet investigation and a Purge feature for rapid Sensor recovery.

POWER ON: Power the Model 950-ASH ON by rotating the Detection Range Control clockwise until a click sound is heard. The blue Power Indicator LED will begin to flash.

After approximately 3 minutes, it will stop flashing and will glow blue to indicate the instrument is ready for use.

SETTING the SENSITIVITY: Rotate the Detection Range Control clockwise until the needle on the LEDs begin to flash. Next, slowly rotate the Detection Range Control slightly counter clockwise until the needle on the Analog Meter Display falls to the 0, 1, or 2 region on the meter scale and the LEDs no longer flash. When set in the HIGH position, the detection range control allows detection of trace levels of hydrocarbons or accelerants.

Using LOW Range reduces the detection sensitivity, so higher concentrations or sources of hydrocarbons/ accelerants are more easily located.

To detect the presence of hydrocarbons/accelerants, scan the suspect material or area of concern at an angle of approximately 45° while holding the Sensor end of the Telescoping Sensor Probe approximately ½” to 1” from the area to be surveyed.

Scan very slowly to provide sufficient time for the vapor to penetrate the Sensor.

NOTE: The time required for a hydrocarbon/accelerant to change from liquid to vapor and diffuse into the Sensor is dependent upon environmental factors such as temperature, humidity, and wind velocity and the type of hydrocarbon/accelerant.

NOTE: to silence the 950-ASH for discreet investigation, put the Mute control in the ON position.

Model C For Arson Investigation and

General Purpose Hydrocarbon Detection

The Model C is a highly sensitive hydrocarbon detector that easily detects fuel oil concentrations of less than 200 ppm or gas leaks of less than one cubic foot per year.

The Model C is a non-calibrated detector used primarily for arson investigation and where it is desirable to detect trace amounts of hydrocarbons.

Operation: Turn unit ON, allow several minutes for warm up, and then scan area of concern. When gas or a hydrocarbon is present, beep tones in synchronism with a red indicator light will occur. A slow beep rate indicates a small amount of gas or accelerant, whereas a more rapid rate indicates a higher gas concentration. A mute switch is provided to silence the audio tones and an electronic purge permits rapid recovery of the sensor.

FEATURES:

Detects Approx. 125 toxic/ combustible gases and/ or vapors -including all heating gases.

Adjustable Sensitivity - Higher sensitivity is used to locate trace amounts of hydrocarbons. Lower sensitivity aids in pinpointing the source in areas of high concentration.

Sensor - Solid state plug in type, housed in a protective guard, mounted at end of 6 foot coiled sensor cord.

Arson InvesƟgaƟon TesƟmonials

" We have used this on numerous incidents to determine if there was any residual hydrocarbon fuels remaining at Point of Origin following suspicious fires. It has allowed us to idenƟfy fires where an accelerant was present to confirm our suspicions. We have also used it to idenƟfy a suspect in an arson fire where we idenƟfied a hydrocarbon residue on the clothing and skin on their arms and hands. We have also used it to confirm a lack of hydrocarbon residue in a vehicle suspected to have been used in an arson fire as an escape vehicle.

We find this We find this to be an excellent tool to assist us in confirming or denying our hypothesis as to cause and origin in our fire invesƟgaƟons. "

Bob Fulton - Deputy Fire Chief City of Dawson Creek, CA

" I have been an arson invesƟgator for four years and have invesƟgated over 50 fires for origin and cause. I have used the Electronic nose on every fire that I have invesƟgated in the last two years. I use to uƟlize this tool when there are factors leading me to believe that a combusƟble liquid may be present. But I now use it on every invesƟgaƟon just to add the informaƟon to my summary report. The department has had two units for over 20 years & they have been a great addiƟon to my invesƟgaƟons and those of my predecessors. For anyone looking looking for a hydrocarbon detector, I would highly recommend this product. "
