Be confident in your purchase, we're an Authorized PCE Instruments Dealer. Highlights: Portable Handheld AC / DC magnetic field detector PCE 0 - 30,000G Portable AC DC EMF Detector Magnetometer Gauss Magnetic Field Meter detects both static (DC) permanent magnet (rare earth) magnetic and dynamic (AC) electromagnetic fields (EMFs) and displays measurement results in gauss (G) or milli Tesla (mT). This portable magnetometer comes with an external sensor and features an RS-232 port for downloading data to a PC. Features: Measurement range: 0 - 30000 G / 0 - 3000 mT Accuracy: 5%; + 20 digits (static) / + 10 digits (dynamic) Resolution: 0.1 G / 0.01 mT Detects both static (DC) permanent magnetic and dynamic (AC) electromagnetic fields (EMFs) Displays measurement results in gauss (G) or milli Tesla (mT) Comes with an external sensor Features an RS-232 port for downloading data to PC Max, min, data hold and auto shutdown power-saving functionality Ideal tool for checking magnetic valves, relays and air-core transformers Useful for assessing permanent magnets and rare earth magnets made of Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), Alnico and Ferrite (also known as ceramic) The external sensor's small, flat tip allows easy access through gaps and into tiny spaces Measures through casings, coverings and housings, eliminating the need to dismantle parts for inspection Specifications: Static (DC) electromagnetic field (EMF) measurements: Measurement range: Range 1: 0 - 300 mT / 0 - 3000 G Range 2: 0 - 3000 mT /0 - 30000 G Resolution: Range 1: 0.01 mT / 0.1 G Range 2: 0.1 mT / 1 G Accuracy: 5 % + 10 digits Measurable frequencies: 50 Hz / 60 Hz Dynamic (AC) electromagnetic field (EMF) measurements: Measurement range: Range 1: 0 - 150 mT / 0 - 1500 G Range 2: 0 - 1500 mT /0 - 15000 G Resolution: Range 1: 0.01 mT / 0.1 G Range 2: 0.1 mT / 1 G Accuracy: 5 % + 20 digits Measurement rate: 1 second Measurement direction: uniaxial Display two-line LC display Functions: Data hold / Max.- Min.- values Operating conditions: 0 - 50 C / +32 - +122F / max. 85 % RH Power supply: 9 V block battery. optional 9 V mains power adapter Input current: ca. 15 mA Meter dimensions: 198 x 68 x 30 mm / 7.80 x 2.68 x 1.18" Sensor dimensions: 195 x 25 x 19 mm / 7.68 x 0.98 x 0.75" Weight: 275 g / 0.61 lb What?s Included: 1 x Magnetometer PCE-MFM 3000 1 x External sensor 1 x 9V battery 1 x Carrying case 1 x User manual
