MONITORING THE ENVIRONMENTAL CONDITIONS is more convenient with the Model EMMA multifunction meter. Humidity, temperature, air velocity, airflow, sound and light measurements are combined in 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 backlight. Besides measuring the current and average reading, the Model EMMA allows the user to read the minimum, maximum and differential measurements for each of the parameters. Included with the meter are the carrying case, rubber boot, battery and tripod.
