Extech Instruments has launched new environmental meters optimized for HVACR and IAQ professionals. The series includes an airflow meter, a combination hygro-thermometer and psychrometer, and a 10-in-1 multifunction meter. The company says the new compact instruments are designed to provide quick and accurate readings on a range of environmental conditions that are essential for HVACR troubleshooting and repairs, as well as IAQ assessments to improve occupant health and comfort.

The meters in the 510 series are equipped with a core set of shared capabilities and features to maximize versatility. The 510 meters share an informative, oversized display and a bright backlight for testing in dark job sites. Useful data functions include data hold, as well as minimum and maximum readings. The auto-power-off function preserves battery life and can be disabled for extended monitoring.
EN510 10-in-1 Environmental Meter measures or calculates air velocity, air flow, air temperature, bead probe (Type K) temperature, heat index, humidity, wet bulb, dew point, wind-chill, and light level. The company says an integrated mini-vane anemometer with low friction ball bearings ensures long-lasting and accurate air-related measurements. 

Leveraging the same mini-vane anemometer design as the 10-in-1 meter, the AN510 anemometer measures focuses on air velocity, air flow, air temperature, and bead probe (Type K) Temperature. The AN510 helps HVACR technicians troubleshoot problems such as hot and cold spots in a residential or commercial space; pressure imbalances; leaky ducts; or registers with little to no airflow. The AN510’s dual display can display air and temperature readings simultaneously for added insights when performing IAQ thermal comfort studies.

Extech’s RHT510 offers the temperature and humidity diagnostic capabilities of the 10-in-1 meter. With the RHT510, a user can assess not only temperature (ambient and Type K) and relative humidity, but also wet bulb and dew point. Wet bulb measurements can be useful in troubleshooting evaporative cooling issues. Dew Point measurements are ideal for controlling or adjusting indoor humidity. For example, IAQ professionals can use dew points to target window condensation and related mold hazards. Like the AN510, a dual display can indicate temperature along with a hygrometer/psychrometer reading at the same time.
