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.
Mitsubishi Electric recently introduced its CITY MULTI® ceiling cassette indoor unit, featuring the new 3D i-see Sensor™. The 3D i-see Sensor is a small component mounted to the exterior panel of the ceiling cassette. The sensor continuously analyzes the thermal profile of a room, identifying cool and warm spots. To achieve an accurate thermal profile, it performs hundreds of circular scans, with multiple points per scan, continuously monitoring.
Belimo Americas has released an advanced butterfly valve designed specifically for the HVAC industry. The company says its newly designed butterfly valve and PR actuator assembly was developed with a focus on ease of installation, application flexibility, and longevity.
The new Fluke Connect®-enabled 370 FC Series Clamp Meters log measurements to pinpoint intermittent faults precisely without the need for the technician to be present. Those measurements are then wirelessly transmitted to the Fluke Connect app on smartphones or tablets and automatically uploaded to the cloud, keeping technicians outside the arc flash zone and away from dangerous moving machinery.
Continental Fan Manufacturing says its new IRIS Damper is a simple solution for fast and exact measurement, balance, and control of airflow. It is ideal for supply and exhaust tracking control, individual comfort control, and any space requiring accurate airflow regulation. Applications for the IRIS damper include office buildings, pharmaceuticals, clean room environments, and laboratories.
Onset has released a series of high-performance, split-core current transformers for measuring AC current and amperage in commercial building energy audits, building commissioning studies, and other applications.
Spirax Sarco has released the MTI10 Insertion and MTL10 Inline Mass Thermal Flowmeter for measurement of gases and air. The MTI10/MTL10 provides measurement of clean, dry gases and air using constant temperature sensing for fast response and low flow accuracy.
ABB has released information in its Vortex (FV4000) and Swirl (FS4000) flowmeters for measuring flow rates of liquid, gas, and steam. The company claims that both flowmeter types offer high accuracy and wide rangeability, as well as an integrated temperature sensor for mass flow measurement of saturated steam.
