The SwitchHolder enables users to activate and deactivate pre-set alarms by sliding movement. An AiroSensor is placed in the accessory, after which the pre-set alarm is activated by sliding the data logger to “on” and disabled by sliding it to “off”. The SwitchHolder is ideal for environments where cooling systems are not operational during specific times, such as weekends. Please note: The sliding motion disables or enables the alarm function. The data logger itself keeps monitoring temperatures, so you will never lose any data even if you forget to switch on the alarm.
