OLC Second-counter

Why choose OLC Second-counter?

Excellent readability of information

Ideal for sterile environments

Classic appearance, minimalistic design

Everything under control

The two independent quadrants and their white background, one for displaying the hour and minutes of the current time by means of two black hands and the other for counting seconds by means of a red second hand and a black minute hand, allow for all information to be read easily and immediately.

Precision is important

Time precision, which is already excellent due to the precise internal clock, can be further enhanced by synchronizing the OLC 7030  with a Master Clock.

It must be kept clean

The frontal glass and stainless-steel frame, that characterize the OLC 7030 when compared to other clocks, simplify cleaning activities and therefore guarantee the hygiene and sterility required in a hospital environment.

More than just the time

L’OLC 7030 is anything but a simple clock, since thanks to its two separate quadrants it can be used as a second counter, which can be useful in certain operating conditions, as well as for displaying the time.

It is an eco-friendly clock

The OLC 7030 is characterized by a low-power consumption: it only uses power during hand movement (meaning when the hour or minute changes) unlike a luminous clock that uses power continuously. It is therefore an ecological clock and perfectly suited for today’s energy-saving requirements.

Easy to control

The second counting feature, characterized by synchronous movement, can be easily controlled thanks to an optional button panel that makes it possible to remote control the starting, stopping and resetting of the device.
