Overview

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 difficult to reach such as busy roadways, yards with dogs, fenced off

areas, and other hard to access places.

The RMLD-CS employs the same technology as the RMLD, known as Tunable Diode Laser Absorption

Spectroscopy (TDLAS). 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 conditions,

temperature, wind, and leak rate.

The RMLD-CS operates under a variety of field conditions including a wide temperature range, light

rain and fog. Its rugged design will stand up to normal field use and operating conditions. Its

Warnings & Definitions

Safety and Warning Information

It is essential that users of this instrument read, understand and follow the instructions for operation

and maintenance. The precautions contained in this manual insure that the instrument is used in a

proper and safe manner.

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious

injury.

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious

injury.

CAUTION

Indicates a hazardous situation, which if not avoided, could result in minor or moderate injury.

DANGER: Do not use the device in an explosive environment.

DANGER:To reduce the risk of ignition of a flammable or explosive atmosphere, batteries must be

recharged only in a location known to be non-hazardous.

WARNING:Read and understand this manual fully before use.

WARNING:Follow the manual instructions and testing methods.

WARNING: The visible green Spotter laser is a Class IIIa (3R) laser product. Do not stare into beam or

view directly with optical instruments.

WARNING:Avoid direct eye exposure to the laser and do not point in the direction of others. Visible

and Invisible Lasers are deployed by this instrument.

WARNING: Substitution of components may impair intrinsic safety. No user serviceable components

contained within this instrument.

CAUTION: Use of controls or adjustments or performance of procedures other than those specified

herein may result in hazardous radiation exposure.

CAUTION: No attempt should be made to repair the instrument. Should the instrument not work

properly, or indicate a fault or warning, refer to the troubleshooting section of this manual.

Definitions

Beam Skip: Occurs when the IR beam jumps between a near object and a far away object. This may

cause a false detection. This can also occur on highly reflective surfaces (windows, water, ice, etc).

Control Module: The portion of the RMLD-CS with the keypad and display that clips onto a harness.

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, increasing with distance. At 100 ft., this area is

22in diameter when shined against a vertical wall.

Infrared (IR): A wavelength of light just outside the range of the visible spectrum.

Laser Calibration Drift: A normal characteristic of tunable diode lasers is that the wavelength

calibration can drift slowly overtime. 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 width of the

plume.

Real Time: A mode that will emit a variable (continuous) Geiger beep rate relative to the

concentration of gas.

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 button located on the keypad.

Tunable Diode Laser Absorption Spectroscopy: A method of gas detection that utilizes a laser that,

when shined through a cloud of methane, will be partially absorbed by the gas which can be

measured for gas concentration.
