This set of two 10A 30kA 1000V fast-acting fuses is an ideal spare for your multimeter. If your co-worker uses your meter and blows the fuse, you will have spares on hand. These fuses are also a great time-saving option if you need to find the fuses in a local electronics supply store. They are brass with nickel-plated fuses, making them durable and corrosion-resistant.
