The EC-2100 is a compact, light weight and battery-operated handheld speedometer designed for use in elevator adjustment, maintenance and inspection. With a wide measurement range and high speed calculation, speed and rotation of a high speed elevator can be measured.

It enables easy and accurate measurement only by pressing the circumferential ring lightly to an elevator pulley or a handrail of an elevator. Measured value can be easily read on the red LCD even in a dark place. The operator can do an inspection alone by fixing the EC-2100 main unit by a jig or using the EC-0201 external detector (option).

As well as the buttons on the main unit, the measurement values can be held by the external contact signal. The each instantaneous value is displayed on the main unit. It supports more safety work without worrying about the displayed values.

Distance measurement is available by the EC-0202 (option). It measures moving distance within the specified time. Moreover by adding the EC-0202 (option) and the EC-0203 (option), the EC-2100 can measure actual moving distance of an escalator after emergency stop operation.

Option

EC-0201 External detector

External detector for the EC-2100 Elevator speedometer. Remote operation using signal cable (EC-0921, standard accessory) provides safety measurement.

*The measurement operations such as power ON and unit selection are performed on the main unit.
