Specifications
RCW-400A is a 4-channel temperature and humidity data logger that not only has wide
temperature measurement ranges, but also provides high precise sensitivity. Its large LCD
screen can display time, current working status, memory capacity and recorded data informa-
tion etc. at the same time. Its embedded buzzer and relay alarm design will give on-site alert-
ing functions, where its SIM card slot design also allows SMS text message alerts via GSM
technology. With the combination of its supported 3G data transmission method and Elitech
cloud platform, users can not only check real-time data online, but also support remote online
monitors and managements on all saved data through the Elitech App and the Elitech cloud
platform via any web browsers.
The standard accessory for RCW-400A is the two-channel sensors wirings: One temperature
and one humidity sensors. Users can extend to four-channel wirings: Two temperature and
two humidity sensors or the four temperature sensors. The battery is built-in rechargeable
lithium battery that also support continuous real-time data uploading and SMS text alerts
even under power outages and blackouts. It can be widely used in food, pharmaceutical, cater-
