The Universal Measuring Head provides accurate depth, speed, and line thickness measurement for slickline sizes as small as 0.062 inch and braided line sizes up to 1/2 inch. This eliminates the need for combination wireline units to carry two measuring heads. By incorporating dual digital encoders for electronic depth, a planetary drive for mechanical depth, and a slickline oiler system; this measuring head covers all of your slickline, cased hole, and open hole measurement needs. The simple side loading, lightweight design makes for effortless installation and maintenance. The Universal Measuring Head incorporates dual digital encoders for electronic measurements, a planetary drive for mechanical measurements, and a slickline oiler. The counter mounts to the overhead spooling arm of a wireline unit or, if a tension device is not installed, a vertical spooler. Imperial and metric configurations are available. Included with the counter is a quick release adapter for mounting a Lee Specialties, Inline Tension Device (sold separately).
