USB temperature and humidity data logger RC-40

USB Temperature and Humidity Data Logger

Product Features:

      Monitor and record temperature and humidity data

      Temperature record cycle could be flexibly adjusted

      Large record capacity. If record every 15 minutes, it could record for more than ten months.

      Big LCD screen can simultaneously display system clock, current work status, record capacity and recorded data.

      The upper/lower temperature alarm temperature could be separately set. It will alarm when the temperature exceeds the upper or lower limit.

      It has USB /U disk interface for convenient data copy and save.

      Form a Local Area Network by RS-485 interface to monitor several data loggers' temperature.

It is matched with our RC-40 data processing software which could real-time monitor, upload, print and manage the data

      It has two alarm output: Buzzer and alarm relay

with rechargeable standby batteries, when the power is cut off, it could keep running for ninety days after fully charged.
