A new user-friendly portable multimeter from Newson Gale Inc. is designed for use in applications involving combustible or explosive atmospheres. The new Model ISDMM multimeter provides convenient, accurate confirmation of a low-resistance path to verified ground points, as well as confirming the integrity of existing bonding/grounding conductors, the company said.
The Model ISDMM also provides readings of DC voltage and amperage, capacitance, frequency, temperature, duty cycle, pulse width and an event counter. It is equally well-adapted to use with permanently bonded equipment or temporary devices such as grounding clamps, cables and reels. It may also be used to ensure the grounding of conductive or semi-conductive hose assembles used for transfer of flammable or combustible products where it is important to achieve continuity over the complete hose length, including fittings. Especially easy –to-use, desired readings are selected on a rotary switch and appropriate test probes or clips are attached to the equipment or conductor to be tested. The ISDMM meter then auto-senses and displays the measurement value clearly on an LCD display, either digital or a 34-segment bargraph. The unit comes complete with a 300-hour alkaline battery and rugged carrying case. Options include a hand-rewind 30-meter extension reel and heavy-duty crocodile test clips. The ISDMM meter is approved according to IECEX and ATEX hazardous area standards and is suitable for used in flammable gas/vapor and combustible dust atmospheres, Newson Gale said. It can be used in outdoor locations, is water and dust tight to IP67 and NEMA 6 standards and has a maximum operating temperature rating of 50°C (122°F). Dimensions are 189 x 82 x 40 mm. (7.4 x 3.23 x 1.57-In.)
