Desktop Multifunction Barometers

Check temperature, relative humidity, atmospheric pressure, and time with one barometer. The included remote sensor has a 200-ft. wireless transmission range for monitoring outdoor temperature and relative humidity in addition to indoor conditions.

Wireless Weather Stations

Monitor nine different weather conditions up to 1,000 feet away. The outdoor weather sensor measures outdoor temperature, humidity, wind speed and direction, rainfall rate, total rainfall, barometric pressure, heat index, wind chill, and dew point. It wirelessly transmits readings to the console by radio signal. Console has built-in sensors to measure indoor temperature and humidity. Console can be placed on a desk or mounted to a wall. It cannot be sold outside the United States due to product registration requirements.

Thermal Imaging Cameras

Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye. These imaging guns translate thermal energy into a color image that indicates hotter areas as brighter and cooler areas as darker, so it’s easy to identify and diagnose problems on instrument panels, HVAC systems, and other equipment. To review footage at a later date, use them to take photos and videos. The lower a camera’s thermal sensitivity, the more precise heat differences it will detect for more detailed images. All are CE marked as meeting European standards for health, safety, and environmental protection. Some include a calibration certificate traceable to NIST stating they’ve passed a test for accuracy.
