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 defl ection is determined by the concentration
and type of hydrocarbon/accelerant detected.
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 fl ashes red. The higher the
concentration, the faster the fl ash rate becomes.
11. Power Indicator:
Blue LED fl 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 ac-
celerants. This is the instrument’s most sensitive de-
tection 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.
15. Power On/Off and Detection Range Control:
Turns
Model 950-ASH on or off and adjusts Analog Meter
to be responsive to the presence of hydrocarbons
or accelerants.
16.
Low Battery Indicator:
Red LED glows when
battery is low or has been depleted. Model 950-
ASH 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 func-
tion is active. Glows red when Purge is complete.
21. Purge Switch:
Turns Purge function on or off . Purg-
ing 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.
