CT/DT/PT Series
|
Through our latest
hand held tachometers, models CT230, PT231 and DT2236, we offer
a range of compact, economical hand held instruments capable
of coping with virtually every type of speed measuring problem
likely to be encountered.
These new instruments employ an exclusive single chip micro-controller LSI circuit with crystal time base. This results in a wide speed measuring range from 5 to 99,999 r.p.m., to a high degree of accuracy. The new refined housing is constructed from light durable ABS plastic giving maintenance free operation for many years.
All units are supplied complete with accessories, batteries, operating instructions, carry case with handle and are ready for immediate use.
