Extech RH350 Psychrometer with 2 Type K Remote Temperature Probes

The revised content is as follows:

The Model RH300 Hygro-Thermometer Psychrometer is a compact and versatile device that simultaneously displays a range of environmental measurements. It can show relative humidity (10 to 90 percent RH), air temperature (-4 to 122 degrees F/-20 to 50 degrees C), and either dew point (-90.4 to 122 degrees F/-68.0 to 49.9 degrees C) or wet bulb (-6.9 to 122 degrees F/-21.6 to 49.9 degrees C).

The device also calculates the temperature differential (T1-T2) between the air temperature and an external probe (TP890), as well as the difference between the external probe temperature (T2) and the dew point. This makes it ideal for field applications where monitoring environmental conditions is crucial.

The RH300 features a unique sensor cap that closes to protect the meter during storage, ensuring its longevity. Its advanced capabilities include data hold, selectable auto power off, and the ability to display minimum, maximum, and average readings from the captured data.

For added convenience, the RH300 comes with a built-in utility that allows for field calibrations using the included RH300-CAL kit. This kit contains 33 percent and 75 percent RH calibration bottles, enabling users to maintain the accuracy of the device in various environments.

The package includes the RH300 meter, the TP890 external temperature probe, the RH300-CAL calibration kit, two AAA batteries, a carrying case, and a user manual. The device also features a built-in RS232 interface (optional RS232 cable 589250) that allows users to download data to a PC for storage and further analysis using the 407752 software.

In summary, the Model RH300 Hygro-Thermometer Psychrometer is a comprehensive and user-friendly tool that provides a wide range of environmental measurements, advanced features, and convenient accessories, making it an excellent choice for field applications and environmental monitoring.
