Digital Multimeter Receives Safety Rating
New digital multimeter from Metrix Instruments has received the safety rating of “intrinsically safe” for use where flammable gas may be present. A patented low-compression sealing system that uses lateral forces rather than pressure from screws keeps contaminants away from sensitive circuitry inside the meter. Case perimeters, push buttons, rotary switch and battery compartment are all separately sealed to prevent contamination. To guard against contact with live leads, a patented device keeps the leads from being accidentally disconnected, and it is impossible to open the meter while the jacks are still connected. An audible beep warns against overloads.
