    Portable Humidity Meters

    Image of Product. Front orientation. Humidity Meters. Portable Humidity Meters.
    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. These humidity meters have a built-in slide rule for calculating humidity without a calculation table.

    Adapters

    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.
    Calibration Certificate Traceable to NIST—Monitors that come with a calibration certificate traceable to NIST have passed a test for accuracy.
    Cannot Be Sold to Canada—Import regulations restrict sales to Canada.
    Adapters—Power these monitors with the included batteries, or add a power adapter to plug them in.

    Accessories for Heat Stress Monitors
    Humidity Calibrators
    Image of Product. Front orientation. Humidity Calibrators.
    To maintain their accuracy, monitors should be calibrated once a year. You can calibrate the monitor yourself using humidity calibrators. These calibrators contain a known humidity, so you can adjust your monitor until it reads the humidity correctly.
