Funkcionalnost
Merilniki delujejo lahko kot dataloggerji ali pa direktno pošiljajo podatke spejemni enoti prek kratkih radijskih valov - brezžično. Njihov domet je 150 m, za podaljšanje pa lahko uporabimo repetitor. Prenos podatkov je samodejen glede na nastavitve oz. ko je sprejemik v dosegu. Vsi merilniki 501 in 502 imajo 16.000 spominskih točk.
RTR-502: External Temperature Sensor for Wide Range Measurement
Other than the Optional Sensor TR-5106, we offer a variety of exclusive RTR-502 optional sensors to meet your needs; from ones with stainless protection to those that can be used in water. Please see the Options Page for more about the sensors.
Download Data via Wireless Communication with a Base Unit
Recorded data can be downloaded from RTR-501/502/503/574 Data Loggers (Remote Units) via wireless communication with a Base Unit.The wireless communication range between a Remote Unit and a Base Unit is about 150 meters [500 ft].By registering an RTR-500 as a Repeater, it can be used to expand the wireless communication range.
Large Storage Capacity: Up to 16,000 Readings
RTR-501/502: Maximum of 16,000 Readings
16,000 readings means you can record every one second and still log four and a half hours of data; or at a recording interval* of 60 minutes you can keep logging for 666 days. A Base Unit can download via wireless communication one RTR-501 or RTR-502 Remote Unit at full storage capacity (16,000 readings) in about two minutes.
Low Energy Consumption Design
RTR-501/502/503
The RTR-501, RTR502, and RTR503 Data Loggers use one Lithium Battery (LS14250). At normal temperature, if recorded data is downloaded once a day or if monitoring is carried out once every ten minutes, the estimated battery life will be about ten months.
Model names which include “L” are designed with a large capacity battery pack. Under the same conditions, L-type models will continue for about four years without the need to change the battery.
