MODEL 950-ASH FEATURES

1. Sensor and LED Arrays: Sensor detects the
presence of hydrocarbon or accelerant vapor.
Sensor is replaceable. White and UV LED arrays
encircle the Sensor.

2. Sensor Guard: Provides a protective enclosure for
the Sensor and LED arrays.

3. Coiled Extension Cord: Allows Telescoping Sensor
Probe to be extended.

4. Telescoping Sensor Probe: Extends for ease of
investigation. Retracted: 19.5”, Fully extended: 45”.

5. Locking Clips: Lock the Telescoping Sensor Probe at
desired length. Open both clips to extend or shorten.

6. Quick Start Guide: Allows user to operate Model
950-ASH with minimal instruction.

7. Audio Sound Port: Produces audible tones when
hydrocarbons or accelerants are detected.

8. Analog Meter Display: Indicates possible presence of
hydrocarbons or accelerants. The degree and speed of
needle de ection is determined by the concentration
and type of hydrocarbon/accelerant detected.

or accelerants.

16. Low Battery Indicator: Red LED glows when
battery is low or has been depleted. Model 950­ASH with low battery has less than 60 minutes of
operating time remaining and should be taken out
of service and recharged immediately.

17. Charging Indicator: Glows red when Model 950-ASH
is charging. Glows green when charging is complete.

18. Light / UV Indicator: Glows blue when ultraviolet LED
array is on. Glows red when white LED array is on.

19. Light / UV Switch: Activates the ultraviolet or white
LED array and meter backlight.

20. Purge Indicator: Flashes red while the Purge func­tion is active. Glows red when Purge is complete.

21. Purge Switch: Turns Purge function on or o . Purg­ing clears the Sensor of any absorbed contaminants.

22. USB Charging Jack: Remove the protective cap and
plug into a USB charger.

23. Rubber Grip for ease of handling and operation.

9. Meter Backlight: Illuminates the meter display in

low visibility conditions.

10. Hydrocarbon/Accelerant Detection Indicators:

When hydrocarbons or accelerants are detected,
the analog meter display  ashes red. The higher the
concentration, the faster the  ash rate becomes.

11. Power Indicator: Blue LED  ashes until the Sen-
sor has achieved operating temperature. When
operating temperature has been reached, the blue
LED will glow.

12. Mute Indicator: LED glows red when Mute is on.

13. Mute Switch: Silences audio.

14. High/Low Range Switch: HIGH Range allows the

detection of trace levels of hydrocarbons and ac­celerants. This is the instrument’s most sensitive de­tection mode. LOW Range is used when an area of
concern has high concentrations of hydrocarbons.
In LOW Range, the sensitivity is reduced to assist in
pinpointing hydrocarbon / accelerant source.
