The PM020-AutoSampler  is a extremely low power SMS alert Unit designed to work with autosampler for up to 5000 Hours standby (base on 12V 5AH Battery). The unit can be power from the Portable AutoSampler internal battery, or can be powered separately via external power. This unit is designed for SMS alert operation for event triggered operation such as Sampler Run and End Of Program Output. Optionally one channel can be connected to external raingauge to log rainfall data and send the data every day to a central monitoring system.
The RTU will wakesup only upon event trigger (Sampler Run, Program End) and send us SMS. Upon successful sending of SMS (or timeout) the RTU will immediately power down to save battery.
Customised Enclosure is  possible to IP67.
