According to the "Chinese People's *** and the State according to law management of measuring instruments catalog (type approval part)" the following equipment is a measuring instrument:
1, rangefinder: photoelectric rangefinder, ultrasonic rangefinder, hand-held laser rangefinder;
2, the latitude and longitude: optical latitude and longitude, electronic latitude and longitude;
3, the total station: full-station electronic tachymeter
4, level meter: level meter;
5, geodesic GPS receiver: geodesic GPS receiver;
6, liquid level meter: liquid level meter;
7, thickness gauge: ultrasonic thickness gauge, X-ray thickness gauge, eddy current thickness gauge, magnetoresistive method of thickness gauge, gamma-ray thickness gauge;
8, thermometer: infrared thermometer (infrared temperature) for the measurement of body Temperature of infrared thermometer (infrared ear thermometer, infrared body surface temperature rapid screening instrument);
9, radiation thermometer: work with the full radiation thermometer, work with the radiation thermometer, work with the radiation thermometer below 500 ℃;
10, balance: non-automatic balance.
Expanded Information:
By structural characteristics of the classification, measuring instruments can be divided into the following three categories:
1, the gauge is that with a fixed form of reproduction of the value of the measuring instruments, such as measuring blocks, weights, standard batteries, standard resistors, bamboo and wood straightedge. Line ruler, etc.;
2, measuring instruments. The amount to be measured is converted into directly observable indicator value equivalent information measuring instruments, such as pressure gauges, flow meters, thermometers, ammeters, voltmeters. Electrocardiograph, etc.;
3, measurement devices. That is, in order to determine the measured value must be the overall combination of measuring instruments and auxiliary equipment, such as mileage meter calibration device, high-frequency microwave power meter calibration device.
