What is a…

Clinometer?

A clinometer, known in many fields as an inclinometer, is a tool commonly used by foresters and/or surveyors to measure slope, vertical angles, and in combination with distance measurements, elevation change or tree heights. The clinometer makes use of basic trigonometry to determine the heights of the objects (References: TheFreeDictionary; Wikipedia).

Hypsometer?

A hypsometer is an instrument for measuring height or altitude. Several physical principles may be used. The earliest types (pressure hypsometers) employed the principle that the boiling point of a liquid is lowered by diminishing the barometric pressure, and that the barometric pressure varies with the height of the point of observation. Modern hypsometers use the combination of a (sonic or laser) rangefinder and a clinometer to measure distances to the top and bottom of objects, and the angle between the lines from the observer to each to calculate height (References: TheFreeDictionary; Wikipedia).

Digital

(electronic) types

• Haglöf Electronic Clinometer (HEC) : Does not have a built-in range-finder. Heights read off at predefined distances. Click here for HEC Users Manual.
• Haglöf Electronic Clinometer/ Heightmeter/ Relascope (HEC-R) : Does not have a built-in range-finder. Heights read off at predefined distances. Use the built-in basal area functions to count number of stems in your HEC-R, using one out of four relascopic factors (0.5, 1, 2 or 4 m² ha^-1). Click here for HEC-R Users Manual.
  
• Haglöf Vertex IV Hypsometer : Has built-in ultrasound range-finder which operates in tandem with a transponder. Calculates angles, and heights at distances of up to 35 m from tree or object. Has built-in basal area function. Click here for Vertex IV User manual.
• Haglöf Vertex Laser VL402 and L402: The VL402 has both laser and ultrasound range-finding options, whilst the L402 has laser option only. Both instruments can determine distances up to 400 m (about 900 m with a reflective target), angle and height. Have built-in basal area functions.

Digital (electronic)

• Haglöf PosTex: PosTex is a new instrument used to position trees and other objects in sample plots. The PosTex and Digitech® Professional caliper form a complete system to systematically measure and position trees.
• Haglöf Distance Measuring Equipment (DME): Get exact distances of up to 30 m or more even in difficult terrain and/or thick understorey. Useful in road construction, building dimension and landscape stakeouts as well as timber cruising work. Select one of the built-in BA factors for prism cruising. Click here for DME User Manual

Increment borers

• Haglöf Increment Borer: These are available in a wide variety of sizes, lengths and core diameters for al types of wood and trees. Click here for information on how to select the right increment borer for your particular application and also how to care for the borer once the purchase is made.
• Haglöf Tree Corer Reader: This precision instrument enables one to scrutinize the details of the extracted core such as growth patterns, age, disease and condition of wood.

Height rods
