Description
Omega Engineering RH-USB Relative Humidity Temperature Sensor USB 2-98% RH
The Omega Engineering RH-USB is a combined relative humidity and temperature sensor with a direct USB interface, allowing connection to a PC without a separate data acquisition module or signal conditioner. The probe outputs digital data over USB and is compatible with Omega Engineering's data logging software. It features a stainless steel cylindrical probe body with a perforated stainless sensing cap that protects the internal humidity and temperature elements while allowing airflow to reach the sensors.

Applications
The RH-USB series is designed for environmental monitoring applications where relative humidity and temperature need to be measured and logged directly to a PC. Typical uses include HVAC performance verification, cleanroom and laboratory environmental monitoring, storage room compliance logging, and research data acquisition. The USB interface eliminates the need for a separate transmitter or analog input module — the probe connects directly to any USB-equipped computer and is recognized as a plug-and-play measurement device. Omega Engineering's RH-USB probes have been used in industrial, educational, and laboratory settings where a compact, self-contained humidity/temperature logger is needed without the overhead of a full data acquisition system. The duct/panel mounting flange allows permanent or semi-permanent installation in air ducts, enclosures, or wall panels.
This Omega Engineering RH-USB Relative Humidity and Temperature Sensor was pulled from a working environment where it was previously in service. It has been visually inspected and is in good used condition. The probe body and stainless steel sensing cap show normal handling wear consistent with lab use. The sensing cap is removable — internal PCB and connector pins are visible and intact. A Techmaster Electronics calibration label is affixed showing calibration date of November 29, 2011, with a due date of November 29, 2012; recalibration is recommended before use in critical measurement applications.
