    OUR BEST SELLER

    The Leica LDT-05 Digital Electronic Theodolite is a technologically advanced instrument for measuring angles and slopes, offering excellent features at a great price. This theodolite offers a measuring angle of five-second accuracy and a three-second telescope resolving power. With a 30x magnification, it is ideal for mapping applications, determining elevation differences, setting out curves, and similar jobs.

    The Leica LDT-05 Theodolite includes an automatic vertical compensation which ensures that accuracy is maintained if the instrument shifts out of balance. It features a visible laser plummet that makes setting over a point faster than optical plummets. Also, it has an objective aperture of 1.8 inches. In addition, this instrument has a vertical angle measuring that includes the percent of grade options.

    Theodolites

    THEODOLITE BUYER'S GUIDE

    Theodolites are a key tool for land surveyors and engineers who have to determine horizontal and vertical angles. Until technology made it possible to automate measures and calculations, using a theodolites involved a great deal of manual setup, manipulation, and math. Now you don’t have to think too much about it because today’s theodolites offer greater ease of use, combined with higher speed and accuracy.

    The digitial electronic technology in modern theodolites eliminate the necessity of manual adjustments and extensive calculation. The optical plummet allows the user to align instrument directly over a reference point without having to use the old plumbob method. The key pad is very easy to use. The measurements appear clearly on the LCD screen within seconds. The accuracy of the angle measurement is excellent with a range of 2 to 20 seconds, depending on the model.

    Types of Theodolites

    There are two different kinds of theodolites: digital and non digital. Non digital theodolites are rarely used anymore. Digital theodolites consist of a telescope that is mounted on a base, as well as an electronic readout screen that is used to display horizontal and vertical angles. Digital theodolites are convenient because the digital readouts take the place of traditional graduated circles and this creates more accurate readings.

    TheodolitesParts of a Theodolite

    Like other leveling instruments, a theodolite consists of a telescope mounted on a base. The telescope has a sight on the top of it that is used to align the target. The instrument has a focusing knob that is used to make the object clear. The telescope contains an eyepiece that the user looks through to find the target being sighted. An objective lens is also located on the telescope, but is on the opposite end as the eyepiece. The objective lens is used to sight the object, and with the help of the mirrors inside the telescope, allows the object to be magnified. The theodolite's base is threaded for easy mounting on a tripod.

    Select the model that is up to the job for you. That means it has all the features you need and will hold up to the condition you will work in, whether they are dark, dusty, damp or downright wet. Its ranking for holding up to water and dust is indicated by its IP rating with 66 being the highest available. If you are going to be working in conditions of low or no light, like underground, in a tunnel or inside a structure without windows, you would benefit from a model with a built-in reticle illuminator and backlit LCD, so that you can view its readings without having to shine a flashlight on it. If you are concerned about operating cost and downtime, look for features like a rechargeable battery pack and charger and backup batteries. Theodolites may also include other convenient options like a sun shade, tool kit, rain cover, drying cloth, plumb bob and carrying case.

    The median price for a theodolite is in the $2000 range, though some advanced models can top $12,000, and some basic models are available for under $800. More advanced models use lasers and keep a record of measurements, allowing you to take repeated or repositioned measurements without stopping to write down the figures and come up with calculation. The data is saved and managed on a computer. That eliminate read and write errors and facilitates the data direct entry into software.
