RS PRO IDM91E digital multimeter (DMM) designed for harsh environments. This handheld DMM is a tool which can measure capacitance, voltage, electrical current and resistance with diode and continuity check. The rugged body guarantees drop prof resistance from up to 1.5 m. The multimeter is also waterproof with a rating of IP54. Featuring fuse protection on both 200 mA and 10 A current ranges and a specially designed beep guard system. That system provides a constant beep warning if the test leads put in the current jacks and select an incorrect function.

The meter is supplied with a protective holster that includes a built-in tilt stand, a nail hook, and convenient test lead storage. This holster provides an extra degree of protection and convenience for your meter.

RS PRO IDM 91E Multimeters are designed to meet Class II IEC 1010 and UL 3111 standards for the safest operation in all applications.

This device has been designed for the most demanding users that value solid construction and highly accurate measurements.
