Meters measure indoor relative humidity and indoor and outdoor temperatures.

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.

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

Check temperature, relative humidity, atmospheric pressure, and time with a single barometer.

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.

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.

Check that floors, garments, and other work surfaces won’t discharge static electricity. These laboratory-grade meters are made in the U.S. and certified to NIST standards for accuracy and reliability. They’re essential in server rooms, clean rooms, and other environments where static could harm sensitive electronics. Also known as surface resistance meters, they’re fully compliant with ANSI for testing and validating workplace static control systems.

To prevent static discharge, surface resistance needs to be less than 1×10⁹ ohms. Our meters measure resistance as high as 1×10¹² ohms, with the results clearly displayed on a crisp OLED screen. Readings are exact to two places, with no rounding to the nearest exponent like with less sophisticated meters.

Each meter comes with leads and two 5 lb. probes. Place one probe on a surface to measure the resistance to the ground (Rtg), or place both on a surface to measure the point-to-point resistance between them (Rtt).

Meters measure indoor relative humidity and indoor and outdoor temperatures.

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.

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

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

Operates on 8-15 VDC. Output is pulse for wind speed and analog voltage for wind direction. Line driver converts the output into 4-20 mA for use with standard PLCs (programmable logic controllers).

Keep an eye on leaks, overflow, and temperature changes near your equipment, even when you’re offsite. These detectors connect to your Wi-Fi to send alerts about moisture, temperature, and humidity to your smartphone or tablet. Place them near tanks and tubs to watch for overflow, or near sump pumps and pipe lines to monitor temperatures and prevent frozen pipes. When water touches one of the sensors on the detector, a buzzer also goes off, alerting anyone nearby. Rated IP44, these detectors are protected from objects larger than 1mm, such as wires, and from water splashing in any direction.

Download an app onto your smart device to program temperature and humidity ranges and set up alerts. You can also create reports that show changes in temperature and humidity over time.

To extend the area they monitor, these detectors come with a detachable cable sensor that senses moisture along its entire surface. Swap in replacement cable sensors for worn sensors, or link several together to wrap around large equipment or trace the path of a pipe. Extend them up to 500 feet from detectors.

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.
