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.

Features
