Humidity and Temperature Data Logger USB RC-4HC

RC-4HC Temperature and Humidity Data Logger This data logger is used for temperature and humidity Recording during storage and transportation of foodstuff, medicine, chemicals and other products. Widely used in all links of warehousing, logistics and cold food chain, such as refrigerated containers, refrigerated trucks, refrigerated package, cold storage, laboratory, etc. Specification: 1. Temperature measuring range: -30 C - 60C; for optional external sensor, -40C- 85C; 2. Temperature accuracy: -30C - 60C, ± 1C; others, ± 1.5 C; 3. Temperature unit: C or F optional, set through RC-4H data management software. 4. Humidity measuring range: 0-99% RH 5. Humidity accuracy: ± 3% RH( 25C, 20~ 90% RH) , others, ± 5% RH; 6. Resolution: Temperature 0.1C; Humidity 0.1% RH; 7. Record capacity: RC-4HC 16000points( MAX) ; 8. Record interval: 10s-24hour adjustable; 9. Communication interface: USB interface; 10. Power supply: inner CR2450 battery or power supply via USB interface; 11. Battery life: in normal temperature, if the record interval sets as 15 minutes, it could be used above one year. 12. Ambient environmental temperature: -30C - 60C; in the low temperature environment, LCD displays slowly, while it has not an impact on the normal measuring nor recording. Once the temperature recovers, it could display normally. Differences between RC-4 and RC-4HC: 1. RC-4 is temperature data logger, while RC-4HC is temperature AND humidity data logger; 2. RC-4 is with the internal temperature sensor and external temperature sensor of 1.1 M. RC-4HC is with one internal temperature sensor and one internal humidity sensor, also with the external temperature sensor.
