Fieldpiece Instruments announces the immediate availability of the ASH3 Superheat Accessory Head, which enables DMMs to measure superheat for both R-22 and R-410A. It does this by measuring both suction line pressure and suction line temperature simultaneously and calculating superheat. At $179, the ASH3 can pay for itself in time savings when diagnosing an air conditioner using superheat. www.fieldpiece.com — 714/257-9060
