Notes: (1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data. (2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval.
MaxTime interval. screws (purchased) to fix the unit. Note: Do not install the device in a metal-shielded box or R718B2 series is suitable for the below scenarios: in an environment with other electrical equipment Oven Industrial control equipment around it to avoid affecting the wireless transmission of the device.

3. Put only 30mm of the stainless probe into the liquid. Sinking the probe into the liquid could damage the sealing compound and thus cause the liquid to get inside the PCB. Note: Do not sink the probe into chemical solutions, such as alcohol, ketone, ester, acid, and alkali. ▼...
7. Information about Battery Passivation Many Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.
