Welcome customer made for special measuring conditions.

As people know the most important feature for a timer is continuously reminding user that the set time is up. But it wastes too much power, especially for battery operated device. Therefore it becomes difficult to make. Under our R/D team’s effort, we designed a special program called PSA (power saving alert) to make this feature realistic. This unique feature is available upon request. Normally the module provides one minute alert.
