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).

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.
