Detailed
Product Information
Model
HC-404 is a self contained,
fixed wavelength infrared
analyzer designed for rapid
accurate analysis of total
petroleum hydrocarbons in
water, soil and sludge samples.
Features
|
• |
Fixed
wavelength 2924cm -1 (3.42µ)
allows for quick analysis
without unnecessary scanning. |
|
• |
Digital
readout in %T and absorbance,
or in concentration mode
for direct ppm readings. |
|
• |
Accomodates
10, 50, or 100mm quartz
cells for analysis to
1ppm or lower detection
levels. |
| • |
Built-in
scale expansion and extended
linear range for high
concentration, using a
simple 3-step calibration. |
|
• |
Peltier
cooled PbSe detector provides
greater than 2500 to 1
signal to noise ratio,
resulting in the very
best detection levels
and excellent instrument
stability. |
|
• |
Small
foot print requires minimal
lab space. |
| • |
Hot
quartz halogen source
for the highest output
possible. |
|
• |
Instrument
simplicity. Intuitive
controls allow for immediate
operation. |
