The Model 725 is a state-of-the-art dual-function environmental meter featuring two sensors housed in a remote wand. This design allows the sensors to be placed exactly where readings are needed. The meter simultaneously displays both Relative Humidity (RH) and Temperature on its triple LCD screen, making it an ideal tool for environmental monitoring in various settings. Additionally, the meter has a second K-type thermocouple port, enabling external temperature measurements.

The Model 725 includes data logging capabilities, recording up to 16,300 data points. Users can adjust the logging interval to capture data over a period ranging from 4 hours to 678 days, making it suitable for both short-term and long-term monitoring. The meter features an RS232 output port and comes with interface software and cable for real-time control from a PC or for downloading data for analysis.
