Manual Densimetro Troxler 3440 Moisture
Next check battery life (if it is a Troxler 3440 or 4640) and reset if needed. Display should show a sign that is charging. The first step is to eliminate the possibility that moisture may have affected the gauge. Remove the keypad from the gauge and disconnect the ribbon cable. Allow the gauge to air dry for at least 2 hours, but.
The Troxler Model 3430 gives you the fast, accurate, and consistent results you need to fulfill the testing requirements on today’s construction projects. The Model 3430 provides the basic features required for determining the density of asphalt, soil, aggregate or concrete and the moisture of soil or aggregate. It and the other gauges in the 3400 series have replaced conventional density test methods and have become the industry standard. The Model 3430 offers you a choice of backscatter or direct transmission for density measurement and backscatter for moisture measurement. The 3430 adheres to ASTM Standard Test Methods D-2922, D-3017, D-2950, C-1040 and AASHTO T-310.
The gauge directly displays wet density, moisture, dry density, percent moisture, percent compaction, void ratio and percent voids in English or metric units. Features & Benefits The Model 3430 gives you these proven advantages for your next field testing project: Minimum keystrokes Easy to follow software All data is easily accessible Runs on rechargeable NiCad batteries or alkaline batteries Keypad, software display, and user manual are available in Chinese, Spanish, French, German or English Related Products.

There are 5 moisture density gauge manufacturers (Instro Tek recently purchased CPN) in the United States. All use Cesium 137 to measure density and all use Americium 241 to measure moisture. Although the quantity of radioactive materials in each of the gauges range from 8 – 10 mCi of Cesium 137 and 40 – 50 mCi of Americium 241, they all give an accurate representation of density and moisture.
When purchasing a new gauge always ask for a discount and be willing to get a quotation from several different manufacturers. Most manufacturers will match competitive quotes but will want to see a copy of the competitive quote. In addition to the discount some companies will offer further incentives such as a free calibration, free leak tests or discounts on future parts and service.
There are many older generation gauges still in use and service and repair centers do an excellent job in refurbishing these gauges. Some gauges still in use are approaching 25 years old. If you have a gauge that is 10-15 years old you will want to consider the options of purchasing a new gauge or refurbishing the gauge you have.
Most gauge manufacturers sell refurbished gauges and give a one year warranty on the gauges. Many independent gauge service and repair centers also sell refurbished gauges. Shop around and compare prices. A refurbished gauge should include a new calibration, current leak test and warranty. You can also buy a used gauge from a geotechnical or paving company that is selling their extra gauges. The price of the gauge is usually lower but you will want to factor in the cost of any potential refurbishing and calibration.
As mentioned, new gauges all use the same radioactive materials and approach to determine density and moisture and should all give the same results. Base model gauges generally require you to manually record (handwrite) your results and standard counts, and manually enter the depth setting. This approach is fine for most gauge users and will save you the cost of unnecessary software.
More advanced and costlier gauges offer all kinds of bells and whistles. You will need to determine if you really need or will use these enhancements. Some will offer loads of data storage that you may not need. Some offer auto storage for your gauge results and standard counts. Other will automatically compute or translate your results. There is a trade-off on enhancements – the greater the number of enhancements the more complicated the gauge. Do you want your gauge operators taking tests or fooling around with software? Make sure it’s worth the effort. And all those extra enhancements can mean more frequent and expensive service and repair bills.
The serial number found on your gun has the answer. While every effort has been made to ensure that the information provided on serial numbers and dates of manufacture are accurate, records on early. A5 Autoloader (New Model). Date, Historic Information, Serial Number Info. 1954-1964, The Model 1955.380 Pistol was introduced in 1954. Exact production figures for each year are not. The model, although invented by JB, wasn't produced as a Browning until 1955, when they were marked 'BAC' and 'Model 1955'. FN made a little over 701,000 of them in the 71 years of production (1912-1983), and I know FN was well into the 20,000 serial number range by 1914 - only two years after intro. The Model 1910 FN Browning was manufactured from 1912 through 1975. Production was halted during the two World Wars, though a few were assembled from parts during the German occupation in World War II. There was no interruption in serial numbers. The FN Model 1910 is a blowback-operated, semi-automatic pistol designed by John Browning. In 1955, the Browning Arms Company introduced the Model 1910 pistol for the American market as the Model 1955. An FN M1910, serial number 19074, chambered in.380 ACP was the handgun used. Browning 1955 fn model 1910 serial numbers lookup.
If you are trading in or disposing of an old gauge many manufacturers will offer an extra discount towards a new gauge, but only if they determine the gauge you are trading in can be refurbished and re-sold. If it’s too old they will not offer the discount and will likely add on a disposal fee. Request that they give you a normal discount and try to include the disposal for free.
