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.

These lightweight windsocks react to the slightest wind movements.

To replace an existing windsock, you must determine the inlet diameter. Lay the windsock flat to measure the inlet and multiply by 0.63 for the inlet diameter.

Individual windsocks come with mounting ties.

Windsock kits come with everything you need for mounting, including an inlet frame, pole, mounting ties, and brackets.

Use these sturdy windsocks to track stronger wind movements than low-velocity windsocks. Inlet frames are sold separately.

To replace an existing windsock, you must determine the inlet diameter. Lay the windsock flat to measure the inlet and multiply by 0.63 for the inlet diameter.

A built-in temperature sensor and a remote-reading probe simultaneously monitor indoor and outdoor temperature.

Monitor your environment when working outdoors. These wristwatches display time, date, temperature, barometric pressure, and altitude. It also has a stopwatch and digital compass.

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.

Measure atmospheric pressure changes in both inches of mercury (Hg) and millibars (mbar).

Meters with calibration certificate come with a document stating they’ve passed a test for accuracy.

Meters measure indoor relative humidity and indoor and outdoor temperatures. Meter with LCD display also measures outdoor relative humidity.

Determine relative humidity within ±4% accuracy and temperature within ±1.8° F accuracy. This meter comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. It also displays dew point or frost point.

For comprehensive system checks and quality control, these meters measure a wider relative humidity range than pocket meters and can determine dew point in addition to humidity and temperature.

The probe is attached to a 3-ft. cable for checking humidity, temperature, and dew point in hard-to-reach areas.

To ensure reliable readings on the go, this portable meter comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy.

Obtain continuous temperature measurements from a wet-bulb and a dry-bulb thermometer to determine relative humidity. This wall-mount psychrometer consists of two mercury-free fluid-filled thermometers, a wick, a glass water bulb, and a relative humidity calculation table.

Monitor relative humidity, temperature, and dew point inside sealed containers. These meters are rated IP67, so they won't expose contents to dust and water. The housing is aluminum, which is lightweight and resists corrosion.

Use smartphones and tablets to monitor humidity and temperature within your system or facility. Connect these battery-powered transmitters to your smart device via Bluetooth, and receive data to ensure workplace conditions are suitable for processes, inventory, or personnel. Good for preventative maintenance and route-based monitoring, these transmitters let you choose how frequently you receive the data, and they’ll notify your device when humidity and temperature levels go outside of your thresholds. Download the app, set your parameters, and collect data from up to 300 ft. away. Rated IP65, they are protected against dust and washdowns.

Turn your transmitter into a portable monitoring system by attaching a quick coupling (not included). This allows fast, temporary connections for on-the-go measurements in different locations.

Monitor humidity in sealed containers without opening them, protecting the inside from contamination. These plugs are often used on plastic bags, storage containers, and electrical housings. Consisting of a mounting nut and two gaskets for a tight seal, these plugs install through a hole in a flexible barrier. Remove one gasket and reverse the nut to install plugs in a rigid container. Watch the indicator disc through the nut’s viewing window—it will change color as humidity rises and falls. Made of anodized aluminum, these plugs resist corrosion and are lightweight. They meet military and SAE standards for humidity indicators.
