WHAT ABOUT OUR PRODUCTS?
We manufacture toxic gas detectors, primarily
used for compliance monitoring in the workplace
Interscan does not manufacture confined space
entry monitors (typified by hand-held 4-gas
monitors---- generally measuring CO and H2S as
well as LEL and O2 deficiency)
Interscan does not manufacture outdoor
environmental (EPA equivalence or reference)
monitors
Although Interscan is certainly aware of other
detection methods, since we manufacture
electrochemical voltametric sensors, this is our
core competency and primary detection method
We can provide other detection methods via
systems integration and custom design
5
WHY CHOOSE INTERSCAN?

• Being both the manufacturer of the sensor and
  the instrument affords Interscan optimum
  applications flexibility

We are a privately held company, providing
reliable and affordable toxic gas detection
solutions for more than 30 years
We know how to solve your gas detection problem!

BASIC TERMS
TLV Threshold Limit Value
TWA Time-weighted average exposure concentration
for a conventional 8 hour workday and a 40 hour
work-week
STEL Short-Term Exposure Limit. Usually a 15
minute TWA exposure that should not be exceeded
at any time during a workday
Action Level This is for benchmark purposes
for the initial screening of a workplace. This
level is one-half of the allowable 8 hour TWA
for a particular substance. Should levels equal
or exceed this amount, then regular monitoring
must be employed
ppm (Part Per Million) 1 ppm 1,000 ppb. 1
10,000 ppm
ppb (Part Per Billion) 1 ppb 0.001 ppm

Early 1900s combustible gas was being detected in
mines
MSA started in 1914
GAS DETECTION A SIMPLIFIED HISTORY
LEL Detection (Methane LEL 5.0)
O2 Deficiency
I.H. Section of the American Public Health Assoc.
started in 1914

40 Years or so after - I.H. section blossomed
into the two associations we know today
A.C.G.I.H
A.I.H.A.
Until this point, gas detection consisted of
level measurements
Monitoring for combustibles does not require
specificity
Monitoring for combustibles does not require
sensitivity

For 30 years Interscan has provided products
ranging from the very simpleto the most
creative in system integration
Our equipment has been installed in
multi-level parking garages, steel plants,
hospitals, pulp and paper mills, power plants,
water treatment plants, and military/aerospace
applications to name but a few
Whether the instrument is one of our Vikane
monitors-- the definitive clearance device
used in the building fumigation industry-- or
our Halimeter (as seen in thousands of dental
offices around the world) you can always count
on Interscan for product reliability, integrity
and matchless support.
