Stroboscope DSL-300-LA

Measuring range 30 - 999999 flashes per minute (FPM)

LED-hand held stroboscope for non-contact determination of revolutions, for monitoring moving parts and ascertain the oscillation frequency of running systems

Industrial stroboscope for battery operation with LCD display and auto-sync laser function

Stroboscope with shock-proofed aluminium housing and 6 LED illuminants

CE mark

Special Features

3 operation modes:
Strobo mode: manual flash rate adjusting
Laser mode: Adjusting the flash rate occurs automatically by using the laser
Tacho mode: Revolution measuring with the laser; the flash function is disabled

Stroboscope DSL-300-LA with easy to read LCD display

6 LED illuminants assure a good illumination of the observing object

9000 Lux at a distance of 20 cm

Double-flash-function (x 2) and half-rate-flash function (: 2) for easy and fast determination of the true flash rate

Adjustable flash duration time for best illumination
– e. g. shorter flash period = tighter image
– e. g. longer flash period = more brightening

Adjustable delay time of internal trigger signal and flash for optimal monitoring of motion sequences

The “slow” function allows to view movement in slow motion

Selected settings can be stored in five separate storage locations

Protection class IP65 (splash water and dust protection)

Battery operated

Additional function: Stroboscope DSL-300-LA-T with trigger input and output

External trigger signal
– Adjustable delay time in milliseconds (ms) between external trigger input signal and flash for optimal monitoring e. g. clock frequency or starting period of a machine
– Phase shift between trigger signal and flash to make a rotating part visible in different degrees
– Pulse divider to determine which input pulse should be used as signal for the flash

Standard Features

Selectable units Hz, rpm or FPM

One hand use

Handy, shock protected housing

Calibration report of manufacturers optional available
