The Dwyer EMMA multifunction meter makes monitoring environmental conditions more convenient than ever. The EMMA combines humidity, temperature, air velocity, air flow, sound and light measurements into one easy to use instrument. The large, dual-line 4-digit LCD display shows both the current and average reading. For reading measurements in dimly lit areas, the display has a built-in back light. Besides measuring the current and average reading, the Model EMMA allows the user to read the minimum, maximum and differential measurement for each of the parameters. Included with the meter is the carrying case, rubber boot, battery and tri-pod.
