|Others||In order to download data via wireless communication, it is necessary to purchase Base Unit:
RTR-500, RTR-500GSM, RTR-500NW/500AW or RTR-500DC
| (*1) When using RTR-500B1 it is necessary to purchase Lithium Battery (LS26500). For details, contact your local authorized distributor.
(*2) The stated battery life is for when it is used in an environment of 25C and recorded data is downloaded at a rate of once a day or "Monitoring Current Readings" occurs at a rate of once every 10 minutes. Battery life depends on measurement environment, recording interval and battery performance.
(*3)The same amount of time will be necessary for each added Repeater.
(*4) The stated water resistance rating is for when the sensor is connected to the unit. However, this does not include the sensor areas for the RTR-503/503L models. Not for continued immersion.
