RCW-400A is a four-channel temperature and humidity data logger with a wide temperature range and high precision. Its segment LCD screen can display the system clock, current running status, memory capacity and recorded data. It has an internal buzzer and can connect an external audible and visual alarm. It can transmit data wirelessly by 3G to our cold chain cloud platform, and users can check real-time temperature/humidity data through web and receive SMS (short message service) alarms by GSM. Users can view, manage and monitor data online remotely by browser or mobile app.
The standard accessories include one temperature sensor and one humidity sensor, which can be doubled into two temperature sensors and two humidity sensors. The data logger has a built-in rechargeable lithium battery which enables continuous real-time data uploading and SMS alarms even in case of power outage.
