GMC-Instruments Gaomei meter M248B frequency meter

METRAHIT ULTRA M248B is a high-precision and high-resolution TRMS system digital multimeter with remote control capability through Bluetooth interface. The M248B also includes temperature measurement and data logging for general purpose applications in the laboratory or on field service calls. The instruments included in the Gossen High Resolution Series are extremely rugged and reliable digital multimeters housed in impact-resistant ABS housings. With a resolution of 310,000 digits and approximately 30 different measurement functions,they’ve been developed for professional use. ±310,000 digit n-triple display,internal error: ± (0.02% rdg). + 20 digits),measurement functions: 1 \u00b5V 600 VDC,10 \u00b5V 600 VAC \/AC + DC trm (bandwidth: 15 Hz to 100 Hz),1 ADC and 10 nA nA - 10 10 AAC \/AC + DC trm (bandwidth: 15 Hz to 10 kHz),resistance,frequency,capacitance and temperature measurements: 1 m \ u00ce \ \ u00ce \ u00a9 u00a9 30 m,0.001 Hz 1 MHz,1 pF 3 mF \u00b0C \ / \u00b0F Pt100 Pt1000,K type thermocouple: -270 to +1372 ºC,automatic range selection and battery cut-off,minimum and maximum measurement value storage,integrated measurement data memory of approximately 2mbyte. 300,000 measured values,sampling rate: 100 ms to 9 h. 3rd,4th cat 300 V or cat 600 V / IEC 61010-1,DAkkS calibration certificate as standard feature \nMultimeter Type = Handheld\ nAbsolute Maximum DC Current Measurement = 10 \nAbsolute Maximum DC Current Measurement = 10 AC\ nAbsolute maximum AC voltage measurement = 600 V AC \ nAbsolute maximum resistance measurement = 30 Momm \ nAbsolute maximum DC voltage measurement = 600 V DC \ nAbsolute maximum temperature measurement = + 100 (PT100 installed) \ u00b0C + 1372 (K) type \ u00b0C +80 (internal)\u00b0C,+850 (PT1000) °C\nAbsolute maximum capacitance measurement = 3mF\nFunction measurement=AC current,AC voltage,capacitance,DC current,DC voltage,diode,frequency,resistance,temperature True valid Value=Yes"
