Wireless Hydronic Differential Pressure Manometer, Series 490W

Dwyer’s Series 490W Wireless Hydronic Differential Pressure Manometer is the most accurate and easy-to-operate manometer on the market. Along with wireless transducers and a mobile device, a single operator using a 490W can monitor and balance a hydronic system in less time and with less manpower than would be possible using a traditional hydronic balancer. In addition, being wireless, the 490W has zero hoses or manifolds – meaning there are no annoying attachments that need to be carried, that can snag onto equipment, or that need to be drained between readings.    Continue reading “On the Job with Dwyer: Series 490W Wireless Hydronic Differential Pressure Manometer”

Discover an Easier Way to Water Balance with the Series 490W

Wireless Hydronic Differential Pressure Manometer, Series 490W

Earlier this year, Dwyer Instruments released its new look and updated features for the wireless hydronic differential pressure manometer, Series 490W. This product is used for applications including: refrigerant pressure testing, hydronic valve balancing, measuring pressure drop across pumps, and measuring pressure drop across chiller and coils for freeze protection.

The original Series 490W hydronic balancing kit was recognized in 2018 at the AHR Expo Innovation Awards as the winner of the Tools and Instruments product category. Prior to this win, the 490W was also recognized as a Silver Award Winner in the Electronic and Hand Tools product category of the Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News magazine (ACHR News).

Monitor CO2 in Schools with the CDT-S Transmitters!

Series CDT-S Carbon Dioxide and Temperature Transmitter

Dwyer recently released its new -S option for the Series CDT carbon dioxide and temperature transmitters. Built upon Dwyer’s standard carbon dioxide transmitter, the -S option has a front-facing LED that illuminates when the CO2 level exceeds 1,100 PPM. 

This new feature addresses concerns raised by legislation, including California Assembly Bill 841 and Nevada Assembly Bill 257. California’s Assembly Bill 841 was signed into law in 2020, while Nevada’s Assembly Bill 257 was approved in 2021. These bills proposed several provisions governing indoor air quality in the public school system, including that each classroom will be equipped with a carbon dioxide monitor that:  Continue reading “Monitor CO2 in Schools with the CDT-S Transmitters!”

What is a Particulate Matter Sensor and How Does it Work?

Series PMI Particulate Matter Transmitter

There are many methods of detecting air quality within a room and in outdoor environments. One of these methods is to measure particulates. Particulate matter can vary in size, and particles 10 micrometers and below are inhalable. (epa.gov) Inhaling particulates like dust, pollen, and smoke can have serious short and long-term impacts on health. Continue reading “What is a Particulate Matter Sensor and How Does it Work?”
