ATH4 Dual Temperature Accessory Head by Fieldpiece
The Fieldpiece Dual-Temperature Accessory, model ATH4, measures two temperatures simultaneously using the included k-type, wrap tab beaded thermocouples. The technology inside the ATH4 provides superior temperature compensation in rapidly changing environments commonly found while performing field service. Use the ATH4 to find Delta T and just about any temperature split you want to measure. Displays T1, T2 and T1-T2 on your Fieldpiece meter, handle or data logger. It is included with the HVAC Guide® System Analyzer to get target superheat and for the Target Evaporator Exit Temperature test. Fieldpiece offers a wide variety of k-type thermocouples for various HVAC specific applications. Use pipe clamp T/Cs with the ATH4 to check for blocked filters. Use wet and dry bulb thermocouples to find target superheat.
Designed for HVAC/R, the Dual-Temperature Accessory, model ATH4, measures two temperatures and calculatesthe difference in English or metric units.
