CAS DataLoggers Inc.: Wireless Temp and Humidity Data Loggers

Thybar Corp.: Custom-Made Rooftop Unit BaseThe T&D TR-71wf/72wf Series wireless temperature and humidity data loggers are two-channel environmental monitors. They have an auto communication function which automatically uploads all recorded data from the loggers over a wireless LAN to T&D’s free cloud service. The temperature loggers use their external sensors to record on two channels in either Celsius or Fahrenheit. A combination logger uses a channel for temperature and a second channel for recording the percentage of relative humidity. The temperature logger measures from -40 to 230°F (-40 to 110°C) using the supplied sensor and monitors a wider range using an optional sensor. The combination logger measures from 32 to 131°F (0 to 55°C) and 10-95 percent rh. Also available is a high-accuracy model of the combo logger with an expanded monitoring range of -22 to 176°F (-30 to 80°C) and 0-99 percent rh. For extended recording, each logger has a logging capacity of 8,000 data sets. (One data set consists of readings for all channels in that type of unit.) The dataloggers feature battery-powered operation.
