Remote Detection for Increased Safety
The HEATH Remote Methane Leak Detector - Complete Solution (RMLD-CS)
is a highly advanced technology, capable of detecting methane leaks from a
remote distance. This technology makes it possible to detect leaks without
having to walk the full length of the pipe line, thus creating safer surveys
in areas that may be difcult to reach such as busy roadways, yards with
dogs, fenced off areas, and other hard to access places.
Tunable Diode Laser Absorption Spectroscopy (TDLAS)
The RMLD-CS employs the same technology as the eld proven legacy
RMLD, known as Tunable Diode Laser Absorption Spectroscopy (TDLAS)
technology.
As the laser passes through
the gas plume, the methane absorbs
a portion of the light, which the instrument then detects.
Based on the local meteorological conditions, a given amount of
gas escaping from the ground will produce a plume that varies in
size and uniformity of concentration levels. The plume, by nature,
is variable and dependent on the soil type, moisture, temperature, wind,
venting and leak rate.
Features
The RMLD-CS includes many features which reduce costs and improve
usage. These advanced features include, but are not limited to:
- User Interface
- Internal Data
Logging
- WiFi
- GPS
- Bluetooth BLE
- Color Camera
- Color Display
- Spotter laser
- Self Test
- Rechargeable and Re-
placeable Battery Pack
- Dual Bay Charger
- Mobile App/3rd Party

Denitions
Beam Skip
Occurs when the IR beam jumps between a near object and a far object.
This may cause a false detection. This can also occur on highly reective
surfaces (windows, water, ice, etc.).
Dark Zone
An area not being scanned due to an obstruction. This may be an elevation
change, the side of a building, behind a curb, etc.
DMD (Digital Methane Detection)
An advanced detection mode which, when activated, will only alert the
operator when there is a probable detection of methane.
Footprint
The surface area covered by the IR beam, which increases with distance.
This area is a 22 in diameter at 100 ft when shined against a vertical
background.
Infrared (IR)
Optical radiation with wavelengths longer than those of the visible spectrum.
Laser Calibration Drift
A normal characteristic of tunable diode lasers is that the wavelength
calibration can drift slowly over time. The RMLD-CS has a built in Self-Test/
Calibration feature to automatically maintain proper calibration.
PPM-M (Parts Per Million Meter)
The product of the methane concentration times the thickness of the plume.
Real Time
An audible mode that will continuously emit a variable beep rate relative
to the concentration of gas. The response range covers 10 – 1000 PPMM.
Spotter Laser
The green, blinking laser which guides the operator as to the location of
the IR beam. This laser can be activated through the left button located on
the keypad.
Tunable Diode Laser Absorption Spectroscopy
A method of gas detection that utilizes a laser that, when directed through
a cloud of methane, will be partially absorbed by the gas and the return
signal can then be analyzed for gas concentration.

Screen Mode - Survey Screen Mode - Graph
The Survey screen mode will display a
numerical readout of PPM-M readings.
This allows the operator a no-clutter
screen while surveying with the
instrument.
During DMD Audio Mode (In Both Survey and Graph Screen Modes)
-Peak and PPM-M values
will turn red while meth-
ane is detected above
the alarm level.
-Peak value is held
for two seconds before
resetting to a lower
current reading.
- Peak value will
instantly change if a
higher reading is ob-
tained by the instrument.
The Graph screen mode will display a bar
graph in addition to the numerical readout
of PPM-M readings. This allows the op-
erator to easily see the changing values
while surveying with the instrument.
FW 1.57-2.39-10 or Newer
The maximum PPMM value displayed is 50K PPM-M. Any measurement above 50K
PPM-M will display ORNG (over-range reading). Readings from 10,000 PPM-M and
higher are rounded to the nearest thousand and appended with a “K”, i.e., 10K, 12K,
20K.
The active operator (DEFAULT, ADMIN, CUSTOM USERS) will be displayed in the top
right corner below the date.
