ALTA wireless pressure Meters measure pressure from a 5 volt pressure transducer and transmits the pressure measurement to iMonnit. By connecting the Monnit wireless pressure sensor to a pressurized gas, liquid or vapor supply line, it can measure the pressure within the line and send data to the iMonnit Online Sensor Monitoring and Notification System. The data is stored in the online system and can be reviewed and exported as a data sheet or graph. User customization allows you to set notifications and alerts from the system so you can know immediately if pressure is above or below an optimal range.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
