The Fieldpiece ATH4
Dual-Temperature Accessory, 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.
Converts the voltages from two K-type thermo- couples to display temperature on any digital multi- meter with industry standard jacks and input imped- ance of 9 or 10 MOhms. For 0.1º resolution, use a DMM that displays 0.1mVDC.
The ATH4 converts the Fieldpiece "Stick" series meter, DL3 data logger and EHDL1 electronic han- dle to a one-piece dual-input temperature meter. Use the optional Fieldpiece ADLS2 deluxe silicone test leads or the AHDL1 adapter handle with the ATH4 for use with DMMs with industry standard jacks.
