Grasslin Segmental Timer

Segmental timers have endless uses in the growing environment from ventilation equipment to controlling irrigation frequency to controlling light-cycles (when used in conjunction with a contactor/relay).

The 24hour period is split into 15 minute segments which can be positioned in either the ‘on' or ‘off' position.  Once set and in use the 24 hour period remains clear enabling the user to check the cycle at a glance, their simple operation makes them much favoured over their digital equivalents. 

Made in Germany, they don't get any more reliable than this - the gold standard in segmental timers!
