Keeping an eye on the ecological conditions is more practical with the Model EMMA multifunction meter. Humidity, temperature, air speed, air flow, noise and light measurements are integrated in one simple to choose to use instrument. The big, dual-line 4-digit LCD show programs both the current and typical reading. For reading measurements in dimly lit areas, the display has a built-in back light. Determining the current and typical reading, the Model EMMA enables the user to check out the minimum, maximum and differential measurement for each of the specifications. Included with the meter is the bring case, rubber boot, battery and tri-pod.
