Digital multimeter

BOSCH PROFESSIONAL GDM 600-16 Digital Multimeter, True RMS, CAT III 600 V, IP65

True RMS readings up to 600 V in an IP65 housing built for daily site work.

The BOSCH PROFESSIONAL GDM 600-16 digital multimeter measures voltage and current up to 600 V and 10 A, plus resistance to 40 MΩ, capacitance, frequency and continuity. Rated CAT III 600 V, it uses an inverted LCD that stays readable even when the meter hangs in front of a panel. A tool for electricians, HVAC technicians and facility maintenance during installation, repair and fault finding.

True RMS accuracy on distorted signals

The meter reads the actual RMS value, so readings stay correct on inverters, VFD circuits and LED lighting. DC voltage accuracy is ± 0.5 % + 2 with 0.1 mV resolution.

IP65 housing with 2 m drop protection

Dust and water jets stay out of the electronics, and the impact-absorbing housing survives drops from up to 2 m. The meter is rated CAT III 600 V for distribution boards and fixed installations.

Inverted LCD for readings from any position

Values stay legible in poorly lit cabinets and ceiling voids. The built-in kickstand and the MH 1 magnetic hanger free up both hands while measuring.

Min/Max/Average recording for fluctuating loads

Peaks and dips during motor or compressor start-up are stored and reviewed after the measurement. Audible continuity feedback confirms a circuit without looking at the display.

Powered by 2 AA cells or a Li-ion pack

Standard AA alkaline cells are available anywhere, while the compatible Bosch 3.7 V Li-ion pack suits daily use without buying consumables. Flexible MS 90 silicone test leads are part of the delivery.
