For new installations and annual maintenance, the combustion analyzer has become a critical tool for HVAC professionals. Used for both furnaces and boilers, the basic hand-held device measures carbon dioxide, carbon monoxide, oxygen, and stack temperature.

While yesterday’s engineers have made great progress, we’re just cracking the surface, and the future relies on the experimental efforts of today’s engineers.

Danfoss has released a new gas detector line for industrial refrigeration applications. According to the company, the detectors are based on a digital platform that delivers multiple communication and integration options for improved operational reliability, calibration and maintenance efficiency, cost-effectiveness, and regulatory compliance. The portfolio ranges from basic to heavy-duty models, complemented by a range of accessories.

The Ruskin® TDP05K advanced thermal dispersion air measurement system for air flow and temperature measuring averages multiple velocity and temperature points within the duct or plenum. Each airfoil-shaped probe can have up to eight moisture-resistant flex sensors.

Air Monitor’s ELECTRA-flo/SD is a thermal airflow and temperature measurement system designed for applications in small ducts ranging in size from 4-in to 16-in diameter. The product provides a calibrated output with an accuracy of ±2-3% of airflow reading from 0-3,000 FPM and a temperature measurement accuracy of ±0.15 ̊ F.

B&K Precision Corp. has purchased Teknix S.A., a service and calibration company based in São Paulo, Brazil.

The Ashcroft 1305D series portable deadweight tester is a pressure calibration system that includes a low range and high range piston assembly, weight set, a hydraulic (oil) test pump to generate test pressures, metal carrying cases, tools, and other accessories.

Palmer's new Model PTG100 Precision Test Gauge has been designed for field and laboratory applications. It can be used for precision pressure measurement and field gauge calibration, etc.

New product advances the use of pressure switches.
