A&D Multichannel Wireless Environmental Temperature and Hygrometer Remote Unit AD-5664-01

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Temperature, relative humidity, heatstroke index, absolute humidity, temperature probe (T1 and T2 are when the optional temperature probe is connected) Temperature 0 to 50℃, relative humidity 20 to 90%RH, temperature probe (sold separately) -40 to 70℃ Temperature -20 to 70℃, relative humidity 5 to 99%RH, heatstroke index 0 to 60℃, absolute humidity 1 to 99.9g/m3, temperature probe (when connecting the optional temperature probe) -40 to 70℃ Temperature 0.1℃, relative humidity RH 1%RH, heat stroke index 0.1℃, absolute humidity 0.1g/m3, temperature probe (when connecting the optional temperature probe) 0.1℃ Approximately 20 seconds 2 AA alkaline batteries
