Intrinsically safe digital multimeters
Features and USP: Fluke 28II Ex is a rugged device used in the toughest environment. It is drop proof up to three metres (9.8 feet) with a totally sealed, IP 67 rated case for complete protection against dust and water. It can withstand hazardous 8000 V spikes, caused by load switching and faults on industrial circuits. It is highly accurate and reliable, providing all the test and troubleshooting power necessary for accurate measurements inside or outside potentially explosive areas. 28II Ex features a high resolution 20,000 count display. It has true RMS AC voltage and current for accurate measurement on non-linear signals. It measures up to 1000 V and 10A AC and DC. Its low pass filter ensures accurate voltage and frequency measurements on variable speed motor drives. The battery lasts up to 800 hours and the separate battery compartment makes it easy to change batteries or fuses on the job without jeopardising the meter’s IS or IP ratings, which might otherwise require sending the unit for servicing.

Features and USP: AVO410 multimeter offers AC and DC voltage and current measurements as well as resistance, frequency and capacitance ranges. It is a unique product offering true RMS readings on the AC functions with standard measurement format. The instrument features a CATIV 600 V safety rating and is perfectly suitable for industrial applications. AVO410 can be used to troubleshoot electrical problems in a wide array of industrial and household environments and in devices such as electronic equipment, motor controls, domestic appliances, power supplies, and wiring systems. The slim, compact case has a tough rubberised holster that sits comfortably in the hand which allows single handed use.
Environmental multimeters and digital TRMS multimeters
Features and USP: KM 19 5-in-1 environmental multimeter has been designed in conformance with IEC-1010 electronic measuring instruments, with an over voltage categorisation of CAT II 1000V, CAT III 600V and Pollution 2. It has been designed to combine the functions of five instruments in one device. These include a sound level meter, a light meter, a humidity meter, a temperature meter and a digital multimeter. It is available in both auto ranging and manual ranging versions. It offers 14 functions in 39 ranges, including over-range protection for all ranges. With maximum voltage between terminals and earth ground 600 V DC or RMS AC, it comes with an LCD backlit display and the data hold function. It displays accurate data and this accuracy is assured for a period of one year after calibration.
Kusam Electrical has introduced another new digital TRMS multimeter—the KM-869. It has a 50,000/500,000 count large LCD display with a 5 sec update rate. It can measure the fundamental voltage and frequencies of most variable frequency drives. It has CAT IV 1KV high safety transient protection. It has an unbeatable 100 KHz DC + AC performance. With a basic accuracy of 0.02 per cent (DCV) and a resolution of 1µV DC, it has auto and manual ranging functions. Its voltage measurement is up to 1000V AC/DC with high impedance. It can also measure noisy high voltage AC frequencies up to 200 KHz in dual display.
Handheld digital multimeters
Features and USP: The U1230 series has been designed to help customers take quick, safe and convenient measurements, even in working environments that are out of the norm.
