Lux meter for measuring illuminance, i.e. incident luminous flux per unit area; Luminance meter for measuring luminance, i.e. luminous flux per unit area and unit solid angle; Light meter, an instrument used to set photographic exposures. It can be either a lux meter (incident-light meter) or a luminance meter (reflected-light meter), and is ...
Displays waveform of a signal, allows measurement of frequency, timing, peak excursion, offset, ... Psophometer: Measures AF signal level and noise Q meter: Measures Q factor of the RF circuits Tachometer: Measures speed of motors Signal analyzer: Measures both the amplitude and the modulation of a RF signal Signal generator
Mechanical probes, the earliest form of precision measurement tools, rely on direct contact for measuring and are now rarely used due to their lower precision. Trigger probes, popularized by Renishaw in the 1970s, utilize pulse signals to determine contact point coordinates, offering precise measurements.

a device used for measuring holes. Hole gauge [3] used to gage internal dimensions of bores that are either too small in diameter for an inside micrometer, and have greater economy than a bore gage or other precision internal gage. Caliper: a device used to measure the distance between two opposing sides of an object. Center gauges and fishtail ...
They allow, for example, the measuring of a narrow o-ring groove. Pitch-diameter micrometers (aka thread mics) have a matching set of thread-shaped tips for measuring the pitch diameter of screw threads. Limit mics have two anvils and two spindles, and are used like a snap gauge. The part being checked must pass through the first gap and must ...
Inside small jaws: used to measure the internal diameter of an object (like a hollow cylinder or pipe). Depth probe, or depth rod: used to measure depths of an object (like a small beaker) or a hole. Main scale (metric): marked every millimeter and helps to measure length correct up to 1 mm. Main scale (imperial): marked in inches and fractions.
Laser rangefinders may be effectively used in various sports that require precision distance measurement, such as golf, hunting, and archery. Some of the more popular manufacturers are Caddytalk, Opti-logic Corporation, Bushnell, Leupold, LaserTechnology, Trimble, Leica, Newcon Optik, Op. Electronics, Nikon , Swarovski Optik and Zeiss .
