Thermco Multifunctional Photo/Contact & Surface Tachometer

DESCRIPTION: One instrument combines the measurements in RPM of many Lab instruments such as centrifuges, motors, and stirrers. The measurement is made in 1 to 3 seconds and the memory feature allows recalling the maximum, minimum and the last reading. One end of the tachometer provides contact readings with a rotating spindle; the other end makes touchless readings with a light beam utilizing self adhesive tabs. The ACCPTC900 utilizes a precision quartz crystal for an accurate time base. Display is 5 3/8" LCD. A NIST Traceable certificate is provided from our ISD 17025/ ILAC accredited Laboratory. The certificate shows traceability to a NIST standard. FEATURES: Power: 4 x 1.5v AA Batteries Included. Carry Case/ Reflective Tape/ RPM Adapter Cone/ RPM Adapter Funnel/ Surface Speed Test Wheel are Included with Unit. SPECIFICATIONS: Range: (Contact 2.5/19,999 RPM. Photo: 2.5 to 99,999 RPM.
