The high-end TRMS multimeters from the METRAHIT PM series: METRAHIT PM TECH, XTRA and PRIME are absolutely robust and reliable digital multimeters developed for professional use. The devices have an attractive design with housings made of impact-resistant plastic and are technically state-of-the-art. The ultra-precise digital multimeter METRAHIT PM PRIME with Bluetooth is an absolutely robust and reliable digital multimeter with a housing made of impact-resistant ABS plastic. With a resolution of 310,000 digits, a basic accuracy of 0.02% and 22 different measuring functions, it has been developed for professional use. Thanks to its integrated Bluetooth interface with the METRALOG smartphone app, it enables measurements to be taken at a safe distance from the measuring point. TRMS precision multimeter and data logger with 310,000 digits resolution with 100 kHz TRMS bandwidthIntegrated Bluetooth interface (optional) and free METRALOG app for Android smartphonesWireless transmission of measured values to a PC/laptop and evaluation with the Windows software METRAwin 10 (option). Precision measurements with a high basic accuracy of 0.02%Measurement via Bluetooth at a safe distance from the objectSaves costs as no interface cable is necessary, reduces on-site effort and also increases safetyOptional PC software METRAwin 10 for recording measurement data on a laptop/PC, visualization, evaluation and logging. With its 22 multimeter functions, the multimeter is suitable for universal use in electrical engineering, particularly in the areas of industry, service, electrical engineering, laboratory and research. The device is suitable for field use and has an internal mains-independent power supply (2 x 1.5 V AA batteries). The Bluetooth interface enables measurements to be taken in environments that are dangerous for humans, e.g. on rotating machines in operation, in control cabinets under high voltage or under extreme environmental conditions such as in climate chambers. 22 multimeter functions Resolution ± 310,000 digits, 5 ¾ digits Basic accuracy +/- 0.02% (VDC) Voltage DC, ACTRMS, AC+DC TRMS, level dB, relative value ¿REL, frequency (Hz, MHz), duty cycle, current DC, ACTRMS, AC+DCTRMS, resistance, diode test, continuity test, capacity, temperature with Pt 100/1000 sensors and thermocouples type K TRMS bandwidth 100 kHz Clip function for current measurement with sensors and converters Switchable 1 kHz low-pass filter Automatic and manual measurement range selection Battery shutdown Light blue illumination Triple display Zero point setting ZERO Min/Max measurement value storage Integrated measurement data memory 2 MByte for approx. 300,000 measured values,Sampling rate 1/10 s to 9 h Bluetooth and IR data interface Mains adapter (optional) Separate battery and fuse compartment Patented automatic socket lock ABS measurement category 300 V CAT IV, 600 V CAT III Rubber protective cover to protect against shock and impact.
