The large-sized “HQ” electronic digital clock is suitable for displaying the exact time, date and temperature is public spaces.

The HQS-Y... digital clocks work with high intensity (4000 µCd) diodes, the distribution of digits is by 5 mm into 7 segments, mounted on a white, smooth-edged metal frame. The front side of the display is dark red, virtually black, which leaves only the lit segments visible.

The viewing angle is 170°.

The HQS-Y... digital clock display can be one sided or double sided, both types are large-sized, so the digits are clearly visible from a distance of up to 125 m.

Thanks to the integrated sensors, the clock is able to adjust brightness based on outdoor light conditions.

The clock can be mounted on a wall or any steel frame, it is suitable both for indoor and outdoor use, although it must be protected from environmental effects (strong sun, rain, snow).
