HHTRT000 Red Lion Controls

Overview

Red Lion HHT / HHTP Series — Handheld Tachometers:

The CONTACT TACHOMETER (Model HHT) incorporates precision bearings instead of gears to ensure long life while providing minimal loading to the rotating shaft. A built-in photo-sensor and slotted disc detect the number of revolutions for a high degree of accuracy. By simply pressing the “MEASURE” button and lightly contacting the conical tip against the center hole of a rotating shaft, the RPM will be displayed and updated every second. By attaching the circumferential speed wheel (included), the Model HHT can measure surface speed in “Switch Selectable” units of either feet per minute (FT/MIN) or meters per minute (M/MIN).

The PHOTO TACHOMETER (Model HHTP) provides for non-contact RPM measurements which enhances operator safety when measuring high speed shafts. By pressing the “MEASURE” button and aiming the Visible Light Beam at a piece of reflective tape (included) on the rotating shaft, RPM will be displayed and updated every second. A display indicator blinks once each revolution to ensure that the reflecting mark is within the 2” to 12” sensing distance of the Model HHTP. Both units can display Memory values which are obtained immediately before turning off the “MEASURE” button.
