Considered the best graphical data logger on the market, Humidity and Temperature Chart Recorder provides technically advanced, portable meters including multimeters, clamp meters, electrical testers, and environmental meters for the measurement of light, sound, temperature, humidity, airflow, RPMs, and water quality.

This numerical and graphical humidity and temperature recorder uses an intelligent LabVIEW™-based PC software. Capable of graphing Dew Point, Wet Bulb, and GPP (grains per pound and measuring humidity (10 to 95%RH) and Temperature (-20.0°F to140.0°F), the Humidity and Temperature Chart Recorder applies to many fields and is an essential tool to monitor controlled environment areas such as freezers, storage areas and other critical areas.

The RH520 Internal Memory can store up to 49,152 measurements for later use and for immediate reference on a PC. The recorder works as follows: a remote (detachable) probe senses the ambient conditions, while the LCD display graphs and provides numerical results of the given conditions. If a preset condition is set, a programmable audiovisual alarm will sound to alert the usual of reaching the set conditions.

Wall mounted and desk mount configurations and an easy to program swivel arm control panel make this instrument a handy recorder for the user. Extech continues to provide essential instruments to the electrical, HVACR, construction, manufacturing, plant/MRO, process and automation, environmental, electronics/testing, and field service/maintenance sectors worldwide.
