The Element HT is a wireless temperature and humidity data logger with digital display. The Element HT is ideal for both HVAC studies and everyday temperature and humidity monitoring in both grow and storage rooms. Designed with external humidity and RTD
based temperature sensors, the device provides a fast response time for both parameters. For customer convenience, functions include starting, stopping and downloading from the device wirelessly from a PC with the use of an RFC1000. This allows customers to quickly access data and spend less time maintaining the device. Data can be provided in
real time back to a central PC, or the device may be downloaded at periodic intervals. For real time monitoring on the go, simply connect the Element HT to MadgeTech Cloud Services, allowing data tobe accessed from any internet enabled device. The digital display provides the current reading for both the humidity and temperature channels with minimum, maximum and average statistics accessible for a quick snapshot of the logged data. The Element HT features user programmable alarm settings for both temperature and humidity parameters. An audible buzzer and LED alarm indicator notifies users when the temperature or humidity is above or below the threshold set in the alarm. This allows growers to take action faster, saving plants, time and money. Email and text alarms can also be configured and sent from within the software, allowing users to be notified almost anywhere.The Element HT can be used as a single, wireless data logging system, or it can be expanded to a large scale system, which can include hundreds of data loggers measuring a number of areas (additional MadgeTech wireless data loggers
and transceivers may be required). The Element HT utilizes the latest MadgeTech Software, version 4.1. MadgeTech Data Logger Software is a powerful, analytic tool. Data can be viewed in graphical or tabular formats and summary and statistics views are available for further analysis. The software features export to Excel®, data annotation, digital calibration and more.
