The new 6-in-1 In-Duct Digital Psychrometer with Enthalpy offers the ability to measure or calculate six parameters using a single instrument. It is designed for in-duct measurements upstream and downstream of the evaporator unit to determine an HVACR system’s efficiency. By calculating enthalpy, the device also allows a technician to assess a system’s efficiency before and after charging with a refrigerant. The instrument’s integral probe is designed for use inside ductwork in order to better measure conditions and diagnose system performance issues. The 6-inch sensor-tipped probe has linear insertion markings and an adjustable rubber bushing. The unit also features a 1.5-inch (38 mm) LCD display. All parameters (except RH) can be displayed in Imperial or metric units.
