Temperaturkalibrator

3005Hadopts the advanced software & hardware technology, which designedforhighaccuracy,multifunctional portablecalibration and widely used in industrial and mining enterprises, scientific research institutes,.universities, military, metrology and other departments. It uses high-brightness display with backlight large screen,.simple operation, sturdy construction, small and portable, compact and economical. So it widelyusedintheinstrumentfactory,metrologylabandothercalibration laboratories,also used in calibration and maintenance for many kinds of thermal meter. In a word,it is an ideal calibration equipment of control instruments.Features1.SPMK3005H calibrator is not only provide a variety of standard signal, but also calibrate the intelligent instruments. It can excellently complete the DC voltage, millivolt voltage, current, resistance, temperature, frequency signal measurement, and provide DC voltage, current, resistance, frequency signal output. Also can calibrate different kinds of data acquisition collector, grapher, multimeter,and other industrial instruments.2.measuring and output 8 thermocouple(K, E, J, T, N, R, S, B), 4 thermal resistance (Pt100, Pt10, Cu100, Cu50), and provides cold junction compensation. Thermal resistance measurement is divided into 3-wire and 4-wire measurement, to provide users more convenience.ParameterGeneral SpecificationsDisplay: 128 × 64 dot matrix graphic LCD with high brightness.Power: AC 220V/50Hz ± 20V, the internal rechargeable battery (3 × 2400)mAh lithium battery power supply.continuous working time: 10 hours (DC24V with no load), DC24V 7 hours with a load.Power off charging time: 3 hours.reference work environment: Temperature: 23 °C ± 1 °C Relative Humidity: (45 75)RH.normal working environment: temperature: 23 °C ± 10 °C Relative Humidity: (20 80)RHStorage Environment: Temperature: -20 °C 55 °C Relative humidity: ≤ 95 RHWorking environment atmospheric pressure: 86 106KPa.measurement specifications DC signal measurement:function output rangesmaximum permissible errorresolutionvoltage0 ± 200mV0.01% R.D +0.005% FS1uV0 ± 30V0.01% R.D +0.005% FS0.1mVcurrent0 ± 25mA0.01% R.D +0.005% FS0.1uVresistance 3 wire0 400Ω0.01% R.D +0.005% FS1mΩresistance 4-wire0 400Ω0.01% R.D +0.005% FS1mΩfrequency0 50KHz0.01% R.D +0.005% FS0.1HzOutput Specifications DC signal output:function output range °Cmaximum permissible errorresolutionvoltage0 +100 mV0.01% R.D +0.005% FS1uV0 +10 V0.01% R.D +0.005% FS0.1mVcurrent0 +25 mA0.01% R.D +0.005% FS0.1uVresistance0 400Ω0.01% R.D +0.005% FS1mΩfrequency0 10KHz0.01% R.D +0.005% FS0.1Hz
