The Extech RHT30 USB HumidityTemperature Datalogger is a great tool for collecting temperature and humidity data inside a room. It is reliable, easy to operate, and provides accurate readings. The logger can be easily programmed, and the data can be easily downloaded. However, some users found that they had to adjust the timestamp format of the data. The price of the datalogger is also praised as being a great value for its capabilities. One user mentioned using the datalogger for work in R&D to ensure that testing labs are within temperature and humidity specifications. They found the device to be very useful in presenting data to support the need for HVAC system replacement. Another user mentioned that they now have accurate readings of humidity and temperature in their cultivation facilities. This suggests that the datalogger can be used in various settings, including plant cultivation. However, there were some negative reviews. One user mentioned that mounting brackets were not included with the product, and the only way to obtain them was to return the entire product, which was inconvenient. Another user reported that the software provided with the datalogger contained a virus, according to their antivirus software on their Windows 10 computer. They also mentioned that the links to the software in the instructions were dead. There were also concerns about the accuracy of the datalogger. One user found that the readings were fairly close in some temperature ranges but up to 10% off in others. For their needs, accuracy within 3% was required. The lack of a certificate of calibration was also mentioned by this user. Overall, the Extech RHT30 USB HumidityTemperature Datalogger seems to be a reliable and easy-to-use device for collecting temperature and humidity data. It provides accurate readings in general, although there may be some discrepancies in certain temperature ranges. However, there are some issues with the software that comes with the datalogger, including reported viruses and dead links. Mounting brackets are also not included, which may be inconvenient for some users.
