Digital Contact Tachometer DT-2235B
Application
1.Measuring RPM is accurate.
2.Wide measuring range & high resolution.
3.Digital display gives exact RPM with no guessing or errors.
4.Used the exclusive MICRO-COMPUTER LSI-circuit and crystal time
base to offer the high accuracy measurement & fast measuring time.
5.The last value/max.value/min.value will be automatically stored
in memory and can be displayed by turn anytime.
6.The use of durable,long-lasting components,including a
strong,light weight ABC-plastic housing assures maintenance free
performance for many years. The housing has been carefully shaped
to fit comfortably in either hand.
