Prototype electronics and build simple automation systems with the configurable inputs and outputs on these boards. Monitor both digital and analog devices, including proximity and temperature sensors, and control basic outputs, such as changing the speed of a servomotor or turning LEDs on and off. Their open-source software makes programming and troubleshooting convenient. Choose a board whose operating voltage can support the other devices you’re connecting to.

Boards with headers are good for making quick connections. Plug them in directly to breadboards, or connect them using jumper wire.

Connect additional ports to your computer. These hubs can run off a computer’s power. USB ports are backward compatible, so they work with cords and connectors that meet the same or a lower USB standard.

Shielded hubs reduce electrical interference from nearby devices to maintain signal strength.

Hubs with a security cable connection lock in place with your computer's security cable to protect against theft.

Measure the intensity of UV light to track equipment performance and ensure safety. These meters are often used in sterilization systems, curing applications—such as coatings and adhesives—and for monitoring blue-light UV radiation from welding equipment. All have a data hold function, allowing you to keep measurements on the screen so you have time to write them down. To preserve battery life, they shut off automatically. These meters are CE marked as meeting European safety standards.

Always wear UV-protective glasses and clothing when collecting measurements. These meters are not for use with lasers.

Meters for UV-A and UV-C wavelengths measure with two sensors, one for long-wave light and one for short-wave light. An included SD card stores timestamped readings in Excel format for transfer to a PC. Save and retrieve the high and low measurements you’ve taken using the minimum/maximum memory feature. The built-in tilt stand props these meters up, so you don’t have to hold them.

Plug an optional thermocouple probe into meters for UV-A and UV-C wavelengths to measure surface temperature. These probes are often used in curing applications to make sure material has reached the required temperature.

Measure light quality and intensity with these meters. They’re CE marked, so they meet European safety standards. They should not be used with lasers.

These meters measure brightness in footcandles and lux. One footcandle is one lumen per square foot. One lux is one lumen per square meter.

Use the data hold function to freeze a measurement on the screen, giving you time to write it down. Meters with minimum/maximum memory let you save and retrieve the high and low measurements you’ve taken. Meters that include an SD card store timestamped readings in Excel format for logging data and transferring it to a PC.

All of these meters measure general lighting. Style C-E meters measure general lighting only—they are not for use with LED lights.

Melt and extrude plastic filaments to build quick and inexpensive prototypes, custom and complex parts, and manufacturing aids such as jigs and fixtures. These 3D printers are also known as fused filament fabrication (FFF) and fused deposition modeling (FDM) printers. They meet U.S. and international standards for safety.

View hard-to-reach areas live on the display. The camera is fitted with an LED, so you can inspect the interiors of machines and ducts. These borescopes can record video and allow you to view recordings on a PC monitor.

Style B borescopes have a smaller diameter and a longer cable than other borescopes to inspect deep inside intricate systems. They have a shorter viewing distance in total darkness, but you can move the camera closer to your inspection area for a better view. Adjust the brightness of the light on the borescope to reduce glare or reflections from shiny surfaces.

Style C borescopes include a hand controller, so you can bend the tip of the scope without removing it from the inspection area. Turn the knob to bend the tip up to 180° in two directions.

Style D borescopes give you 360° control over the tip. Their hand controller has a joystick that you can use to bend the tip up to 180° in all directions without removing it from the inspection area. Use the included magnetic stand to hold the borescope when it’s not in use.

View live footage from two inspection angles directly on these borescopes. Great for collaboration, the LCD monitor is big enough for multiple people to see. These borescopes also store images and video to an included SD card, so you can transfer them to other devices for future reference or compliance needs. Because they have two cameras, you can quickly toggle between the front and side view instead of backing up and turning the probe. Bend the flexible probe to pivot into tight spaces. These borescopes are often used to inspect equipment, tanks, drains, and HVAC systems for repairs. Both cameras have an LED light to illuminate dark areas. To adjust the brightness of the light or change the camera’s view, use the controls on the handle.

Rated IP67, these borescopes won’t get damaged from dust, even in areas with continuous airflow. They can also withstand temporary submersion in up to one meter of water.

Borescopes with two-way tip control maneuver through winding passages since you can bend the tip in either direction using a knob. They combine the pliability of flexible probes with the control of rigid probes.

Connect these borescopes to your smart device to take high-resolution photos and videos of hard-to reach areas. The camera is mounted on a cable and surrounded by bright LEDs, so you can inspect the dark interiors of machines and ducts. Download an app onto your device to control the lights and camera, as well as to record, store, and share images and video. Your smartphone or tablet functions as the screen to view images and videos.

Borescopes with a flexible probe bend to navigate around corners and obstacles better than a rigid probe. They have more precise positioning of the camera to see into nooks and crevices.

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.

Import regulations restrict sales to the listed areas.
