This handheld device displays CO, CO₂, air temperature, rh, dew point, and wet bulb temperature measurements.

This product line is designed for continuous gas monitoring in multiple application settings.

Much like subcooling, understanding and calculating superheat can be somewhat difficult for newbie technicians.

This monitoring system detects problems before a central residential air conditioner breaks down. It provides real-time data and historical data on vapor pressure/temperature, superheat/subcool, liquid pressure/temperature, amperage, daily run time, and status of overcharged/undercharged units.

Available for commercial and industrial applications, this product supports safety compliance inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities, and walk-in freezers by monitoring for refrigerant leaks for numerous gases including HFCs, HFOs, HCFCs, CO2, and ammonia (NH3)).

According to the Environmental Protection Agency (EPA), a typical food retail store leaks an estimated 25 percent of refrigerant, or approximately 1,000 pounds, annually.

Weighing 11 pounds, this product is a rugged coil cleaning machine that blasts dirt from evaporator and condenser coils using a patented, pressure-activated pump that delivers two pressure settings: low pressure for indoor coils and high pressure for outdoor condenser coils.

This product is designed to keep air conditioning drain pans and lines from clogging and to eliminate foul and musty odors.

First out in the new “R” series line of fixed infrared sensors, this product is a non-contact temperature sensor designed for use in OEM equipment and industrial process control and monitoring applications.

At the AHR Expo, RectorSeal LLC highlighted several new products designed to combat leaks and corrosion, both on the inside of the unit and from salty sea breezes on the coast.
