Handheld elevator speedometer with 5-digit backlit LCD, 100 ms update rate, 0.1 m/min resolution, analog and pulse outputs, 211×80×36 mm, 270 g, includes accessories and carrying case
The LANDTEK ES-2100B is a handheld instrument built for elevator adjustment, maintenance and inspection. It weighs 270g including two AA batteries and measures 211x80x36mm. A 5-digit backlit LCD shows upper and lower values with a 100ms update rate. Resolution reaches 0.1 m/min when averaging ten or more samples.
Unlike simple rotation counters, this unit provides statistical averaging and memory functions for compliance reporting. The jump is worthwhile when maintenance logs require documented speed trends rather than single readings. Analog output delivers 0 to 1V with ±1% linearity and 10ms refresh, while pulse output supplies 800 pulses per rotation via open-collector transistor.
Continuous use is rated from 0 to 45°C at 35 to 85%RH, with storage tolerance from -10 to 60°C. The 10-bit D/A conversion maintains ±1% full-scale linearity during long test sessions. Pulse width stays between 0.5 and 1.2µs under load. Standard kit includes circumferential ring, contact tip, hold cables, manual and carrying case.

The unit measures 211 x 80 x 36 mm and weighs 270 g including the two AA batteries.
Attach the circumferential ring and rotating contact tip to the motor shaft; a common error is reversing the tip direction, which gives no pulse output.
The two 1.5 V AA batteries power the meter and will need periodic replacement; the rotating contact tip can also wear with heavy use.
