Gurley has been a major designer and manufacturer of precise measuring instruments since 1845, and a leading supplier of optical encoders since the mid-1950s. We have a full catalog of standard products; most of them are on our web site. Please call if you don't see what you're looking for.
Although we have many catalog items, our real strength has always been our willingness and... (read more)
The compact design of pygmy meters - the bucket wheel is just 3/4 inch by 2 inches in diameter - allows measurement of shallower and lower velocity flows. The pygmy meter provides reliable measurements of flows down to 0.05 feet per second at depths as shallow as 3 inches. Except for the absence of a five revolution click, these models operate identically to the larger Price type meters... (read more)
The model 7700 Incremental and encoder is a compact, non-contact modular encoder with superior performance. Available in many resolutions and configurations, it is easy to install and its optional commutation tracks eliminate hall effect sensors for brushless motors.
Features common to both models include:
- LED illumination for long life (>100,000 hours)<.../li>
The Models LA18, LA20, LA25 and LA35 are optical absolute linear encoders designed for long life in medium to high-performance applications. The compact LA18 offers measuring lengths up to 1.2 m (48”); the almost-as-compact LA20 measures up to 1.5 m (60”); and the more robust LA25 and LA35 have a maximum measuring length of 2.0 m (80...

Optographics is the production of precision masters and the replication of these patterns in metallic depositions or photographic emulsions on various substrates. At Gurley Precision Instruments, we have taken Optographics from its infancy to the continuously expanding state of the art that we have today. Some of our more standardized Optographic products include:
Reticles,... (read more)
Combination of low, standard and high pressure Gurley Densometers and smoothness testers
Our flagship instrument. The Model 4340 combines the abilities of our textile, standard and high pressure Densometers, S-P-S Testers as well as our programmable digital timers and provides a reading in seconds, thus reducing the time required to test a material. (read more)
Troy, NY – Gurley Precision Instruments' high-performance A08/R108 series rotary encoder offers both incremental (to 4,096 counts) and absolute (up to 12-bits) position information in an 8mm diameter package. Available in both a shaft and blind hollow-shaft configuration, the A08 and R108 offers design engineers several unique mounting and interface options. (read more)
Gurley Precision Instruments introduces a new magnetic encoder, the M122, which offers high performance in a small package (22-mm). The M122 includes a microchip equipped with a matching rotating magnet that provides four output options: binary parallel, synchro-serial (SSI), incremental (quadrature) and analog. (read more)
The A58 is the highest resolution compact encoder available for applications requiring precise measurements of distances and angles in a relatively small package. The low cost and high accuracy of this encoder make it an ideal solution for practically all applications which require absolute positioning. Mechanical features include a 58-mm diameter aluminum housing, a 3mm to 0.25" diameter stainles... (read more)
GPI Models R112S and R112B optical rotary incremental encoders are designed for light industrial applications that require high resolution in a very small package. Available in either shafted or blind-hollow shaft versions, these encoders are only 12mm dia x 25mm long with resolutions up to 8,000 cy... (read more)
The model A37 mini encoder is a 12-bit single-turn absolute rotary encoder with opto-electronic technology. These encoders are used in a wide variety of position-sensing applications for the measuring of angles and distances in relatively small envelopes. Mechanical features include a 37-mm diameter aluminum housing, a 3-4 mm (0.125-0.25") diameter stainless steel shaft... (read more)
