Page 7: General Description
GENERAL DESCRIPTION The G •T LZ-30 is a methane selective, laser-based gas detector. The device is based on world-leading photonic technology and is designed using the effect that methane gas absorbs a certain laser wavelength, and the absorbing strength is related to the concentration of the methane. The device is a handheld gas detector, for the remote detection of methane and gases containing methane (natural gas and naturally occurring sources of methane). -

Page 10: Product Features
PRODUCT FEATURES •T LZ-30 instruments are constructed of durable flame-retardant polycarbonate plastic to withstand the rigors of field use. The housing contains a rechargeable Lithium Ion battery, which is charged by inserting the instrument into the charging base. Open-path TDLAS technology ensures that gas detection is instantaneous, accurate, and methane specific –... -
Page 11: Beam Dimensions
PRODUCT FEATURES IMENSIONS The G •T LZ-30 produces a conical beam of laser light, that starts from the front of the instrument and gradually spreads as the distance increases. At the maximum detection distance, 30m, this beam is 8” in diameter. This is depicted in the image below (not to scale). -
Page 12: Sensor Technology
SENSOR TECHNOLOGY ETECTION The G •T LZ-30 uses open path TDLAS (tunable diode laser absorption spectroscopy) technology. The laser generates a specific wavelength of light that is sent through the gas monitoring area, partially absorbed by any methane source, and reflected back to the instrument by the reflection surface. -
Page 13: Explanation Of Ppm•M
EXPLANATION OF PPM•M The G •T LZ-30 displays its readings in parts per million meter (PPM•M). This is a representation of the average gas concentration over 1 meter, or roughly 3.3 feet. The detection laser of the G •T LZ-30 measures the amount of light absorbed by a concentration of gas. -
Page 14: Battery Charging
BATTERY CHARGING The G •T LZ-30 has an internal, rechargeable lithium-ion battery pack, and includes a recharging base. This battery is not user replaceable. To recharge the internal battery, ensure that the charging base is plugged in and insert the instrument into the base, bottom first. Contacts on the bottom of the instrument touch spring loaded pins in the bottom of the charging base to make an electrical connection. -
Page 15: Operation And Use
OPERATION AND USE : When the G •T LZ-30 is powered on, the laser WARNING module(s) will be energized. MENU 1. Press and hold the button until the screen illuminates. The software version will be displayed during a brief warmup period (~15 seconds). - Page 16 OPERATION AND USE 6. Using the visible targeting laser, survey the area according to federal, state, municipal, and/or company procedures. Observe the readings on the display and any alarm conditions that should occur. In general, it is good practice to conduct investigations using an ‘S’ or ‘Z’ pattern to maximize the area that is scanned.

Page 17: Operation And Use Tips
OPERATION AND USE TIPS Factors such as line of sight, wind, and sunlight conditions are not something that most operators have had to take into account in the past. This section gives a few tips and tricks for getting the most out of the G •T LZ-30. -
Page 18: Shape Of The Detection Beam And Line Of Sight
OPERATION AND USE TIPS HAPE OF THE ETECTION EAM AND INE OF IGHT Since the G •T LZ-30 uses a point of light for targeting, it can be easy to forget that the actual detection path is in the shape of a cone, which starts from a point (the instrument) and gets wider on the path to the target. - Page 19 OPERATION AND USE TIPS HAPE OF THE ETECTION EAM AND INE OF IGHT Another thing to consider is that the size of the beam can affect the reading that the instrument gives, depending on the size of the plume. Consider the picture to the right: the green colored beam is roughly the same size as the plume of gas, which means that the instrument will be...

Page 20: Wind Conditions And Plume Size
OPERATION AND USE TIPS ONDITIONS AND LUME Since the path of the laser has to pass through the methane plume for detection, wind conditions can greatly affect how the instrument operates. Because of this, especially when scanning a large area, it makes sense to have a plan of attack. -
Page 21: Locating Targeting Laser
OPERATION AND USE TIPS OCATING ARGETING ASER With bright sunlight, the targeting laser may be difficult for some to see. This is unfortunately a downside of any technology of this nature. There are a few things that can help with this. One thing that might help in this scenario is to begin tracking the laser from a location where you can see it clearly. -
Page 22: Calibration Check (Bump Test)
CALIBRATION CHECK (BUMP TEST) : The built-in calibration cell in the carrying case must be used for WARNING bump testing. The calibration gas in the cell is certified for 3 years (labeled on the cell), after which it is considered to be expired. Cells can be sent into SENSIT Technologies to be refilled and recertified. -
