Rugged Oil/Water Interface Meters
When working in hazardous or explosive environments,
use the certified intrinsically safe Rugged Interface Me-
ter or Rugged Mini Interface Meter.
Ideal for remediation sites, oil refineries, and landfills,
these meters accurately measure the thickness of hydro-
carbon product layers (LNAPL) as thin as 1 mm (1/200 ft)
floating on the water table and sinking layers (DNAPL).
• Meters: Both full-size and backpack-size meters are
available. The economical Rugged Mini Interface
Meter is ideal for shallow wells or high water tables.
• Probe: The field-replaceable probe includes a lens
and infrared light emitter. A stainless steel shield
protects the lens. The infrared light emitter sends a
beam of light through the lens to a detector, which
identifies conductive liquid (water) and non-con-
ductive liquid (product). A solid tone and solid light
indicate oil. An intermittent tone and a flashing
light indicate water.
• Tape: ASME-certified tape is constructed of high-
tensile steel with yellow tape jacketed in clear
Kynar® coating. Kynar protects tape from hydro-
carbons, solvents, and other harsh contaminants.
Graduated in meters by mm or in feet by 0.01 foot.
• Intrinsically safe: Grounding cable ensures safety
at hazardous sites. Certified to CSA and ANSI/UL
standards. Class 9098-01 for hazardous locations.
Class 9098-81 (U.S.A.) for hazardous sites. Class I
groups A, B, C, and D.
• Electronics:To conserve battery life, the meter shuts
off after 5 minutes of inactivity.
Rugged Conductivity/Level/Tempera-
ture Meter
Accurately measure conductivity, water level, and tem-
perature in wells, boreholes, and open bodies of water.
Use this meter to profile conductivity and temperature.
• Probe: To measure conductivity, the probe uses a four-
electrode system that includes two arrays
of a single electrode within a concentric electrode. Each
array reverses its polarity 1,000 times/
second. This system reduces corrosion of the electrode
to ensure reproducible readings. Water level
is detected when the probe passes from a non-conduc-
tive medium (air) to a conductive medium
(water with conductivity levels greater than 10 μS/cm).
• Tape: ASME-certified tap is constructed of high-
tensile steel with easy-to-read yellow tape jacketed
in medium-density polyethylene to ensure longev-
ity. Graduated in meters by mm or in feet by 0.01
foot. The tape is potted directly into the probe (sac-
rificial security link is not available on this meter).
• Electronics: Electronics module houses an LCD
screen that displays conductivity values up to
80,000 μS/cm, and temperature from -20 to 85° C
(-4 to 185° F). Module includes a bright red LED and
a buzzer. To conserve battery life, the meter shuts
off after 5 minutes of inactivity.

• Superior tape construction improves accuracy and du-
rability. Choose from high-tensile steel tape with poly-
ethylene jacket, or high-tensile steel tape with hydro-
carbon-resistant Kynar® coating, or Kevlar®-reinforced
polyethylene tape.
• Reels stand up to field use. Durable flanges are con-
structed of impact- and UV-resistant nylon. Polyure-
thane-coated steel frame and stainless steel axle in-
crease longevity.

TROLL® 9500 Water Quality Sensors

Conduct ISCO, ISCR, Biosparging,
Air Sparging & More
The TROLL® 9500 Instrument supports real-time
measurement of performance indicators, which allows
for a dynamic work strategy per the EPA Triad Approach
to site remediation. You can adapt to changing condi-
tions as new data becomes available. This allows you to
complete projects more quickly and at a lower cost than
when using traditional approaches. The TROLL 9500:
• Features sub-2 inch configuration for key param-
eters: DO with the RDO® Sensor, conductivity, pH/
ORP, temperature, and barometric pressure
• Deploys in harsh conditions.The corrosion-resistant
housing is suitable for many remediation applica-
tions.
• Reduces grab sampling and labor costs while im-
proving safety when working with treatment chem-
icals Improves performance and reduces mainte-
nance when deployed with the RDO Sensor
• Connects to the TROLL® Link Telemetry System for
remote access and external power
You can use the TROLL 9500 System
with Flow-Sense Software to conduct
low-flow purging and sampling. You will
collect representative samples, minimize
contaminant volatilization, and reduce
hazardous waste disposal. To improve
efficiency in the field, the system:
• Automates collection of well and
pumping information
• Monitors and records stabilization of key
water quality parameters
• Automatically generates defensible
calibration and sample reports hat
conform to federal and regional
regulations
• Eliminates transcription time and errors
Automated Test Setup
Flow-Sense Software retains all project information—
well data, pump performance specifics, tubing details,
pumping rate, stabilized drawdown, and parameter sta-
bilization criteria. You can quickly access site informa-
tion at subsequent sampling events without reentering
data.
in-Situ® Sync Software automatically copies well records
and data between a computer and a RuggedReader®
Handheld PC.
Automated Data Collection
Stabilization criteria are set for each monitored param-
eter. Data collection intervals are defined by time or
pumped volumes. During sampling, software calculates
and displays variance and targets for each parameter.
Data is logged at pre-determined intervals and stabili-
zation is achieved when readings meet variation crite-
ria.
In addition, you can view data numerically or graphi-
cally.
Automated Test Report Generation
After stabilization, stored data can be exported into Ex-
cel®. Flow-Sense Software automatically generates full
calibration and sample reports that conform to federal
and regional regulations. To save time, simply reuse
templates at subsequent sampling events.

The In-Situ® Con TROLL® PRO system is designed for
process control and continuous monitoring applica-

ent, effluent, and treatment processes. Contact your
regional EPA coordinator and state regulator for de-
tails, or visit the In-Situ web site to start using break-
through technology.

RDO PRO Optical Technology
The second generation RDO sensor measures dis-
solved oxygen (DO) using the principle of“dynam-
ic luminescence quenching.”The
RDO sensor uses lifetime-based optical fluores-
cence technology to provide an extremely stable,
accurate, low-maintenance DO sensor.
Sensor optics include a lens, blue LED and filter,
red LED and filter, and a photodiode. When the
blue LED emits light, it causes the lumiphore mol-
ecules embedded in the gas-permeable sensing
foil to emit red photons.
The RDO sensor measures the “phase” (or delay)
of the returned signal compared to the excitation
signal, and is thus based on the “lifetime” rather
than the“intensity”of the luminescence.
The presence of oxygen in the foil quenches the
luminescence and causes a phase shift in the re-
turned signal, detected by the photodiode. The
phase difference between the blue excitation
light and the return red light is measured, and the
result is used to quantify DO.
RDO PRO Offerings

PRO system or with SCADA/PLC systems
