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).

Take field measurements of temperature, dew point, heat index, wind chill, wind speed, and relative humidity.

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.

When long life with little maintenance is critical, rely on the same rugged weather equipment used by the National Weather Service. For a complete weather station, you'll need at least one sensor, a sensor cable, and either the Weather Data Center Display or one of the Real-Time Displays.

All mount on vertical 1" pipe (1 3/8" OD). Mounting hardware is included; pipe is not included. Connect to power using screw terminals.

(A) Temperature/Relative Humidity Sensor—Includes a shield that maintains accurate temperature readings by reducing sensor exposure to solar radiation and precipitation. Operates on 10-28 VDC. Output is 4-20 mA.

(B) Barometric Pressure Sensor—Operates on 7-30 VDC. Output is 4-20 mA. Enclosure (sold separately) is required. Optional wind screen reduces variance in measurements caused by wind gusts.

(C) Wind Speed/Wind Direction Sensor—Operates on 8-15 VDC. Output is pulse for wind speed and analog voltage for wind direction. Optional line driver converts the output into 4-20 mA for use with standard PLCs (programmable logic controllers).

(D) Rainfall Intensity Sensor—Does not require a power supply. Output is pulse.

Weather Data Center Display (For Sensors A-D)—Presents live readings from up to eight sensors and logs more than two million readings for later upload to your PC using an RS-232 serial communication cable (sold separately). It can also be programmed to activate alarms on up to four readings. Resolution is 0.1° F for temperature, 1% for relative humidity, 0.01" Hg for barometric pressure, 1 mph for wind speed, 1° for wind direction, and 0.01" for rainfall. Display operates on 10-30 VDC or the included 115 VAC adapter with 6-ft. power cord and two-prong plug. Overall size is 5 11/16" Ht. × 7 7/8" Wd. × 2 1/8" Dp.

Real-Time Displays (For Sensors A and C)—Get accurate, real-time data from either the temperature/relative humidity sensor or wind speed/wind direction sensor. Alarms activate when your chosen thresholds are reached. Resolution is 0.1° F for temperature, 1% for relative humidity, 1 mph for wind speed, and 10° for wind direction. Displays can be linked in parallel to feed multiple displays from a single sensor. They operate on 12-30 VDC or the included 110 VAC adapter with 6-ft. power cord and two-prong plug. Overall size is 5 11/16" Ht. × 5 11/16" Wd. × 1 7/16" Dp.

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

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

Determine relative humidity within ±1.5% accuracy and temperature within ±0.8° 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.

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.

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

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.

Also known as sling psychrometers, these calculate relative humidity in the field based on continuous temperature measurements from a wet-bulb and a dry-bulb thermometer. They consist of two mercury-free fluid-filled thermometers, a wick, a glass water bulb, and a handle.

Psychrometer with ±5% relative humidity accuracy has a built-in slide rule for calculating humidity without a calculation table.

Install the small display in tight spaces and crowded instrument panels up to 10 feet from the probe.

Obtain the most accurate readings possible with these thermometers that include a calibration certificate traceable to NIST that states they’ve passed a test to fall within ±0.5° F accuracy. The thermometer probe is connected to a cable, so the display can be mounted away from your system for remote viewing.

Measure temperature, humidity, and radiant heat in your work area to keep your team safe from heat-related hazards. These monitors help you avoid dangerous conditions and comply with OSHA standards for a safe work environment. They use a variety of measurements from your surroundings to calculate the heat stress index and the wet bulb globe temperature (WBGT), which tell you how hot it feels. Set a maximum wet bulb globe temperature, and an alarm will go off when heat reaches the safety limit.

These monitors have two sensors. One measures temperature, humidity, dew point, and wet globe temperature. The other measures black globe temperature, which is the effect of direct solar radiation on an exposed surface. Carry monitors with you to measure different areas, or mount to your tripod to measure conditions over time.

To maintain their accuracy, monitors should be calibrated once a year. You can calibrate the monitor yourself using humidity standards. These standards contain a known humidity, so you can adjust your monitor until it reads the humidity correctly.

Monitors that come with a calibration certificate traceable to NIST have passed a test for accuracy.

Power these monitors with the included batteries, or add a power adapter to plug them in.

Add a memory card to store your readings and export them to a computer.
