It is extremely shock-resistant due to its robust design and is heads up to 3 meters the multimeter (Echteffektiv-DMM) has an ATEX and IECEx approval for mining (M1), the zone 1 (gas) and 21 (dust) and is specified in accordance with IP67 water – and dust-proof. For more information see this site: Ultra Wellness Center. The variety of other approvals, E.g. for the American, Brazilian, Chinese and Russian market, the multimeter is can be used worldwide. Due to its robust design, is extremely shock-resistant and is heads up to 3 meters. That makes 28 II ex ideally suited for measurement and error request on intrinsically safe circuits. In addition, it allows the meter outside of the ex-hazardous area – measurements up to 1000V and 10A.
As a further instrument can be saved and thus exclude the danger, to connect a multimeter (DMM) not approved for intrinsically safe circuits. Another safety feature is the approval after the over-voltage protection standard according to EN 61010-1:2001 CAT III 1000V and CAT IV / 600V. The 28 II ex offers all the functions which a Multimeters must have to carry out important measuring tasks and troubleshooting in the ex-area. A built-in low-pass filter can also provide accurate voltage and frequency measurements of motor drives with adjustable speed. Common functions such as recording of min/max/medium and peak are available as well as an audible alarm and warning message if the test leads are connected to the wrong inputs.
A display background lighting ensures good legibility of the measured values, even in poorly lit areas. The batteries or fuses can be quickly and easily exchanged, without having to open the device: A separate battery compartment ensures the quick exchange. Approved accessories may also be used in hazardous areas. While temperatures are recorded with the thermocouple or thermistor, also flows can be determined with the clamp meter – without the otherwise necessary interruption of the connections – quickly and easily. The 28 II is the ideal to ex Multimeter to perform measurements inside and outside of the ex area with any precision.
