Fieldpiece Instruments, maker of tools and test instruments for the HVACR field service technician, introduced two feature-packed portable digital refrigerant manifolds at the recent 2011 AHR Expo in Las Vegas. Both the new SMAN2 and SMAN3 are the only refrigerant manifolds that automatically calculate target superheat, letting technicians correctly charge any air conditioner or refrigeration unit. In addition, the manifolds measure and display dual temperatures and pressures, as well as calculate and display superheat and subcooling simultaneously.
Other handy features on the SMAN2 and SMAN3 include dual K-type thermocouple pipe clamp inputs, a large temperature and glare-resistant backlit display viewable from 20-ft., extremely long battery life (500 hours for SMAN2 and 135 hours for SMAN3) with constant battery status, and 39 built-in P-T charts. Plus, the sturdy hook makes it easy to hang the manifolds while on the job or in the truck, and the padded nylon bag ensures techs don't have to remove hoses and clamps every time they complete a job.
