The Ministry of Maritime Affairs and Fisheries designated the “Cold Chain Specialized Zone in the hinterland of Incheon New Port” in June. It is expected that a 57.18-acre freezer/refrigeration specialized zone will be created and a new cargo of 80,000 TEU per year will be created.

How to manage numerous and remote refrigerated/freezer containers? Not only the temperature but also whether the door is well closed or not will be a control point. By attaching the Radionode RN400-T2EX, there is no need to worry about the refrigeration of external containers in a heat wave. ▲ Temperature recording ▲ Emergency notification ▲ Power failure/door open notification ▲ Warning light control and other services are provided. Multilingual alarm service is provided by phone / text / email to the person in charge registered for each site. It can be fixed with screws or attached with a magnet, so it can be installed without expensive construction.

It is not difficult to build a large-scale refrigerated/freezer container temperature remote monitoring. Solve it with RN400-T2EX, which enables real-time monitoring with a PC in the office or a smartphone outside.

Easy-to-use, real-time air quality(tVOC) recorder UA50!


Android connection OK, laptop connection OK,
Measurement data CSV sharing OK



Have you ever had a headache in the office? Air quality, what did you manage? Here are sensors that detect odors from solvents commonly used in industry, organic gases emitted from chemical/pharmaceutical plants, nearby paint and painting facilities, laundry rooms, gas stations, and even mold.

Radionode UA50 measures the total organic compounds (tVOC, 0 ~ 60ppm) referring to these substances. Since it is a USB type sensor, measurement starts immediately when you connect it to the smartphone using the C type gender / USB extension cable included at the time of purchase. A Swiss sensor with fast reaction speed is installed to check the VOC concentration in real-time. You can also check data trends (graphs) and share data with Tapaculo Mobile, a free dedicated monitoring app (Android).

Indoor air quality management! Measuring carbon dioxide is no longer enough. The UA50, which can manage VOC and CO2 at the same time, is easy to carry and can be purchased online such as Wismax, Chanju Tech, and Device mart.
