Combustible Gas Leak Detector - Test Meter GD-3300 with case
Very sensitive electronic gas detector with flexible 16 inch gooseneck probe detects LPG, CNG gas leak and 15 different combustible gases. The Combustible Gas Leak Detector has a long slim Goose-neck probe to find leaks in tight areas. Its' adjustable alarm, easy one-hand operation and impact resistance storage case add up to value and convenience.
Easily operate the Combustible Gas Leak Detector with one hand to detect presence of combustible gases. Audible and visual indicators help pinpoint leak source. Adjustable "tic" rate helps eliminate background gas concentration in contaminated environments.

To ensure accurate readings use it only when ambient air is within this range: Temperature: 32 to 120°F Humidity: 10 to 90% RH (non condensing).
The GAS detects a wide variety of gasses, including some toxic gasses, and nuisance vapors. The following lists represents only a portion of the more common gasses it will detect.
Combustible detected by GD-3300:
- Natural Gas
- Carbon Monoxide (not to quantify)
- Jet Fuel
- Hydrogen Sulfide
- Industrial Solvents
- Lacquer Thinner
GD-3300 Electronic Gas Leak Detector user manual:
Before using this Instrument, read all safety information carefully. In this manual the word "WARNING" is used to indicate conditions or actions that may pose physical hazards to the user. The word "CAUTION" is used to indicate conditions or actions that may damage this instrument.
If you are using your Combustible Gas Leak Detector as a result of a service call, chances are someone has either smelled a combustible gas leak or someone has reason to believe gas may be leaking. While you're Combustible Gas Leak Detector is designed to function without producing sparks or otherwise igniting the gases it detects, the environment you are responding to probably has no such safeguards. Most combustible gas leaks are noticed long before concentration levels build up to the point that explosion hazards exist.
If you feel an explosion hazard exists: • Arrange for evacuation of people in the area • Call proper authorities from a safe location • Shut off gas source is possible • Ventilate enclosed areas if possible to do so without risk of ignition • DO NOT switch power switches on in area of question As a matter of routine, ventilate the area you plan to work in. Ventilation will help ensure the gas does not accumulate in large volume where it can attain its Lower Explosive Limit (LEL)*
LEL: Lower Explosive Limit - The point at which a combustible gas, when mixed with air, has developed the minimum concentration to combust when exposed to a source of ignition. The LEL IS usually stated as a percentage of gas in air as a fuel-air-ratio, or as parts-per-million (PPM) in a

Instructions Switch on the gas-leak detector by sliding the ON/OFF button and the READY light is glowing. The Combustible Gas Leak Detector runs through a one-minute warm-up and self-zeroing sequence when it is first turned on in fresh air. The alarm of the instrument may very loud without contact any gas. That is caused by the high Tic Rate preset in rotary
Rate (Sensitivity) Adjustment the time the instrument is put into service, you should conduct a quick functional test. Adjust the Tic rate to non-alarm level. Then, simple expose the sensor to a known leak, like a cigarette lighter, or pass the probe over a drop of combustible fluid. After the initial warm-up, the instrument can be used to detect combustible gasses. When the sensor in the probe tip detects a combustible gas, the tic rate will increase and the instrument sounds a warbling tone while the ALARM light. As the concentration of gas increases so does the tic rate.
If the situation calls for quiet operation, or if background noise makes it difficult to hear the built-in speaker, you can use an earphone. The jack is at the top of the instrument. Note that listening to the alarm or tic through the earphone is very loud.
If the READY light is off, the batteries are low. They should be replaced immediately. Low batteries will adversely affect the instrument's reliability. See the replacement procedures.
Adjusting the Tic Rate(Sensitivity) The tic rate tells you when the sensor (in the tip of the instrument) is getting close to a leaking gas. You can control the tic rate using the rotary wheel in the center of the instrument. • Move the wheel clockwise to increase the frequency • Move the wheel counterclockwise to decrease the frequency
A tic rate of 4 to 8 tics per second, in fresh air, is typical. As the sensor comes near a combustible gas source, the tic rate increases. In order to isolate the source of a leak, you may need to move the wheel counter clockwise, decreasing the sensitivity, as the sensor moves closer.
Replacing the Batteries
Replace your 1.5 volt /size R14C(B) alkaline batteries when: • The green READY light off • No light or other activity occurs upon turning the instrument on To replace the batteries: 1. Lay the instrument face-down on a back face. 2. Remove the battery cover. Apply upward pressure to the tab at the bottom of the battery cover while lifting it out. 3. Remove the batteries using a coin or screwdriver, if necessary, to pry them out. 4. Replace all three batteries with new ones.
Replacing the Sensor
Although the sensor is designed to offer many years of reliable service, it may become inoperable if it is submerged in liquid or otherwise physically damaged.
To replace sensor:
1. Turn the instrument off
2. Remove the upper tip guard by pressing straight up from the alignment notch that separates the two halves of the tip guard.
3. This is a sturdy component, but use caution bending its leads.
4. Pull the sensor straight up from its tip housing.
5. Replace the sensor, pressing it straight in.
6. Reassemble in reverse order.
