Wireless Measurement Data Logger WBGT Meter (Compliant with JIS B 7922)
HD35EDLW1N7GTC.J: [WBGT Index] 920MHz Wireless Data Logger (Slave Unit) by Senseka
Measure and log the WBGT index (in accordance with JIS B 7922)! Perform wireless communication at 920MHz with an access point and remotely monitor in the cloud!
The HD35EDLW1N7GTC.J is a subunit (data logger) for the Senseca wireless measurement system "HD35 series" designed for WBGT measurement. ■ Compliant with JIS B 7922, it supports the measurement and recording of WBGT (Wet Bulb Globe Temperature), making it ideal for heatstroke prevention measures. ■ Measures WBGT, temperature, humidity, wet bulb temperature, and black globe temperature, transmitting data to the main unit via 920MHz wireless communication. ■ Equipped with an LCD display, allowing real-time confirmation of measurement values such as WBGT, temperature, and humidity on-site. ■ Calculates and displays WBGT values for both indoor and outdoor (sunlit) use, accommodating various measurement environments. ■ Measurement data can be centrally managed on a PC or cloud, enabling long-term recording, analysis, and remote monitoring. ■ When set thresholds are exceeded, it quickly notifies abnormalities through alarm emails and integration with remote alarm modules. ■ Features an IP67 dustproof and waterproof structure and battery operation, making it ideal for installation outdoors in construction sites and sports facilities. ■ Perfect for WBGT monitoring in high heatstroke risk areas such as construction sites, schools, sports facilities, parks, and event venues. *For more details, please download the PDF or feel free to contact us.

Applications/Examples of results
For managing heatstroke risk in various scenes such as construction sites, parks, and sports venues, measurements can be temporarily taken. WBGT, temperature, humidity, wet bulb temperature, and black globe temperature are transmitted to a master unit via 920MHz wireless, allowing for remote monitoring on a PC or in the cloud. It can also be used for email notifications when warning thresholds are reached, as well as alerts through alarm modules, rotating lights, and announcement machines.
