Two portable digital manifolds - SMAN2 and SMAN3 - 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. The SMAN3 includes a micron vacuum gauge, a micron alarm, and vacuum timer. The micron alarm enables technicians to set the alarm to a chosen micron level, and when the vacuum reaches that level, the alarm will sound, so technicians can continue working without constantly checking the vacuum. The vacuum timer is useful to track how long a vacuum has been pulling because if it’s taking longer than a technician would expect, it may indicate hidden issues. 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 feet, extremely long battery life (500 hours for SMAN2 and 135 hours for SMAN3) with constant battery status, and 39 built-in P-T charts.
