2056E mechanical inclinometer is a dual scale ball-in-tube type inclinometer. The top scale is ±6 degrees with 1 degree increments. The bottom scale is ±60 degrees with 5 degree increments. The housing is made of rugged ballistic plastic, making these clinometers extremely tough for all types of environments and weather conditions. The glass tube and ball construction provides smooth roll for accurate measurements. With operating temperature ranging from -45°C to 82°C the 2056E is the perfect all-season inclinometer. The large, clear number and degree markings make it easy to get quick readings.
