Results are displayed in feet, yards, or meters. Specifications: Range: 0 to 1000 meter maximum 2000 meter to reflective target Resolution: 0.1 meter; Accuracy: +/- 0.3 meter
Digital hand-held anemometers are also available.


Precision, hand-held sighting clinometers, for measuring vertical angles, slopes, bedding dips and heights of distant objects. Case is machined out of solid aluminum. Scale rides on a sapphire jeweled bearing and are liquid damped. Scales are graduated in degrees from 0 to +90 and from 0% to +150% slope. Values can be read directly to one degree or one percent and estimated to 10 min. of arc or one-fifth of one percent with readings near zero level. Absolute accuracy is about one third of a degree.


KP90N Digital Planimeter is used for area measurements from maps and other sources with an accuracy of +/- 0.2%. Clear LCD screens display readings up to 8-digits. 6-Digit pulse count allows user to measure an area 100 times larger than with an ordinary planimeter- up to 10 square meters. It features a hold memory function that holds a value in memory. For even more precise measurements, a mean value can be calculated from several measurements. The computing function model has a built-in computer for instant conversion of measured areas into a unit and scale value of choice.


The "circle over circle" alignment system of this compass assures an accurate reading every time! In addition, a round bubble level allows for more accurate strike and dip measurements. The compass features three inclinometer systems: card inclinometer (±5° accuracy with 5° resolution), hinge inclinometer (±5° accuracy with 5° resolution), and graduated dial inclinometer (±1° accuracy with 1° resolution).

The laser distance meter is meant for both indoor and outdoor measuring. It is the first hand laser distance measurement device which has an integrated digital viewfinder (3fold zoom). With this invention measurements can be made in difficult lighting conditions and even if the laser dot is not visible. Additionally the device has an integrated tilt sensor which opens a much wider variety of indirect measurements. For simple inclination measurements the housing simply has to be held at the object.


This mirror sighting height gauge is great for teaching students how to quickly determine tree heights! Easy to follow instructions are embossed onto its rugged plastic shell, detailing the gauge’s short four step measuring method and height-finding formulas.
● Mirror sighting height gauge is a simple, but effective tool for measuring tree heights.
● Great teaching aid for quickly determining heights.
● Simple, 4-step instructions are embossed on the plastic gauge.


An economical unit for lab or field use. This portable mirror stereoscope is for use with 9" x 9" stereo photographs. It features a 1.3x magnifying unit, and the rugged plastic frame folds to compact size of 2" x 6-1/2" x 14". Also available is an optional eyepiece with a 3x magnification and a 55-75 mm inter-papillary adjustment. The field of view is 12° and it has a close-up focus of 150 mm. Constructed of durable plastic to fit precisely on your geoscope.Using positive curvature (magnifying) lenses, the focus point of the image is changed from its short distance (about 30 to 40 cm) to a virtual distance at infinity. This allows the focus of the eyes to be consistent with the parallel lines of sight, greatly reducing eye strain.
● The card image is magnified, offering a wider field of view and the ability to examine the detail of the photograph. ● The viewer provides a partition between the images, avoiding a potential distraction to the user.


This versatile digital pedometer offers a wealth of data at your fingertips for all of your walks. Offering detailed information, this pedometer measures steps, distance walked, time elapsed and calories burned Counts up to 99,999 steps, Belt clip offers trouble-free placement.A pedometer is a device, usually portable and electronic or electromechanical, that counts each step a person takes by detecting the motion of the person's hips. Because the distance of each person's step varies, an informal calibration, performed by the user, is required if presentation of the distance covered in a unit of length (such as in kilometres or miles) is desired, though there are now pedometers that use electronics and software to automatically determine how a person's step varies. Used originally by sports and physical fitness enthusiasts, pedometers are now becoming popular as an everyday exercise measurer and motivator. Often worn on the belt and kept on all day, it can record how many steps the wearer has walked that day, and thus the kilometres or miles (distance = number of steps × step length).


The GEKOM is a robust stratum compass available at a moderate price according to the measuring method of Prof. Dr. Clar allowing the measurement of the azimuth of dip and angle of dip in one single operation. As the vertical circles are visible from above, the azimuth of dip and angle of dip can be read at a glance.The upper part of the housing can easily be removed for the adjustment of declination and inclination. The housing is made of antimagnetic and resistant solid light metal with a surface protection anodised in blue colour; compass needle: automatic arresting when the needle is not in use, North end red, South end black, with adjustable inclination weight, length of needle: 44 mm, horizontal circle diameter 60 mm, interval of graduation 2°, reading by estimation 1°, anticlockwise numbering every 10°, cardinal points are also shown with the East and West markings reversed, declination adjustment up to 360°, diameter of vertical circle 19 mm, dip measuring range 270°, graduation interval 5°, reading by estimation 1°, numbering every 20° in quadrants, cover plate with friction adjustment screw, dimensions of closed compass 86x70x20 mm, weight 240 g.

15. Geological Stratum Compass.

All-metal, German-made geological compass, based on the design by Dr. Clar, University of Vienna, for measuring azimuths and dip angles. Hinged cover has a graduated vertical operation. Dip angle graduation is 5 degrees over a range of 225 degrees, with reliable estimation to 1 degree. Mirror mounted on the inside of the cover in combination with notch and bead sights on the face of the compass enable accurate sightings to distant objects. Compass graduations are 2 degrees with reliable estimation to 0.5 degrees. Compass needle is unlocked with a push button.


This concrete test hammers are used for the non-destructive measurement of the rocks compressive strength as well as for detecting weak spots. The compressive strength (fc) is established by measuring the hardness (rebound value R) of the surface and with the conversion curves. The Type L/LR hammer operates with significant lower impact energy, making this hammer the ideal option for testing thin walled items with a thickness between 2” and 4” (50 to 100 mm) or for testing small components. The Type L/LR is suitable for testing cast stone components which are sensitive to impact. In rock mechanics, the Type L/LR hammers are commonly used for classification testing of rock cores and brittle rock. This L type Schmidt hammer is supplied complete with plastic carrying case, grinding stone and instruction manual.
