The accumulator is composed of a crystal oscillator time control circuit with high precision and no need to set. It will start counting and accumulating when it is powered on. It is widely used in equipment and devices (such as engineering vehicles, excavators, generators, etc.) It is used to display the cumulative working time of equipment and equipment. Working voltage: DC12-36V Timing range: 0-9999.9 hours (h) Color: Black Material: plastic Package Contents: 1 x excavator timer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
