External Relative Humidity (RH) and Temperature Probe

The RH Temp External Probe works with the ACR SRX2 Temp RH Logger and SmartReader Plus 2 to measure temperature and humidity at a remote location. With its simple four-wire connection and one-meter cable, it’s ideal for monitoring conditions inside chambers, ducts, or other enclosed spaces while keeping the logger easily accessible for setup and data download.

Description Specifications Q&A

The RH Temp External Probe is designed for use with both the ACR SRX2 Temp RH Logger and the SmartReader Plus 2. It enables accurate measurement of temperature and relative humidity at a remote location from the main logger.

When connected, the probe provides dual-location monitoring — one set of sensors built into the logger, and another positioned remotely where conditions need to be tracked directly.

With a 1 m (3 ft) integrated cable and a simple four-wire terminal connection, setup is quick and straightforward. Once the external channels are enabled, you’re ready to log data.

This arrangement is especially useful when the sensing point is in a tough-to-reach or environmentally challenging area, such as inside a chamber, duct, or enclosure. The logger can remain easily accessible for setup and data download, while the probe measures conditions precisely at the point of interest.

Operating over a 0 to 95 % RH range and a broad temperature span, this probe delivers reliable readings across a wide variety of indoor and controlled-environment applications.
