Brief Analysis of Thermal Calibration Instrument of Process Instruments
The thermal calibrator is a desktop comprehensive verification instrument with built-in high-capacity lithium-ion battery for power, measurement and output parameters and physical parameters. In addition to current, voltage, millivolt and frequency signals, there are 8 thermocouples (J, K, T, E, B, R, S, L, N) and 6 thermal resistances (PT1000, PT200, Cu50 can output Current signal

How to operate the current transformer on-site thermal calibrator
The on-site thermal calibrator of the current transformer is an important part of the power system measurement equipment. The accuracy of the thermal calibrator directly affects the accuracy of the electricity bill measurement for the user of the measurement equipment. Therefore, the regular inspection of the current transformer on-site thermal calibrator is what the power sector does. At present, most of the traditional transformer inspection methods in China use relatively poor methods. That is, the secondary load (usually in lieu of the load load) of the transformer inspected when the transformer is inspected is compared to a standard transformer of the same scale. The booster (voltage) supplies the quantum with current (voltage), and the quantum's secondary (differential voltage) signal is input to the checker. This inspection method requires a high current (voltage) power supply unit, a standard transformer and load bank of the same scale. When the primary current is greater than 1000A, the power supply device reaches tens of kilovolt amperes, which is bulky, difficult to wire, and inconvenient to verify the transformer on site.

What matters should be paid attention to in the use of the refrigeration thermostat
Before using a refrigerated bath, refrigerated baths place a liquid medium in the tank. The liquid level is 30mm below the workbench, and the heater is not enough to energize it so as not to burn out.

What is the function of the refrigeration thermostat? In what areas is it mainly applicable?
Refrigeration constant temperature bath is an ideal temperature detection experimental instrument and constant temperature experimental instrument with computer intelligent control, PID self-adjustment adjustment, high temperature control accuracy, small temperature fluctuation, high cooling efficiency, low noise, and stable operation. Safety. The low temperature temperature control tank can be divided into vertical low temperature constant temperature and horizontal low temperature temperature control tank in appearance design. At present, there are many factories producing refrigerated thermostatic baths on the market. Although the specifications are also different, factories classified as DC are more common.

Thermocouple Calibration Furnace: An Introduction to Thermocouple Calibration Furnaces
Thermocouple calibration furnace is one of the main components of the thermocouple detection device. It forms a complete detection device with the watt-hour meter and the standard thermocouple matched with the temperature control device. Measures various industrial thermocouples. In the laboratory, this tubular laboratory furnace can also be used for chemical analysis and physical measurements. The automatic temperature control device of the thermocouple detection furnace is adopted, and the temperature controller realizes the automatic temperature control according to the PID adjustment method. The following are special inspections and calibrations for inspection equipment.

Make the "quality inspection report" stand up to quality inspection
The quality inspection report is the "physical certificate" of product quality, the "safety certificate" of consumer behavior, and the "letter of credit" of the market economy. The whole society should pay more attention to quality inspection reports and establish and improve supervision mechanisms according to law.

Recently, Suzhou local standard DB3205/T1021-2021 "Service Specifications for Metrology and Calibration Institutions" was released and implemented. Based on the characteristics of the metrology and calibration market, the "Service Specifications for Metrology and Calibration Institutions" specifies terms and definitions related to the services of metrology and calibration institutions, general requirements for services, basic requirements for metrology and calibration institutions, service provision process requirements, complaint handling, and service quality evaluation and improvement. requirements, and the basic service procedures for laboratory calibration and basic service procedures for field calibration are provided in the appendix section. By standardizing the measurement and calibration service process, it provides standard guidance for the providers of measurement and calibration services to continuously improve service quality and service level, and also provides a strong basis for the customers of measurement and calibration service agencies and government regulatory authorities to evaluate and supervise measurement and calibration service agencies. Thereby promoting the healthy development of the metrology and calibration industry and providing strong technical support for the development of the economy and society.

Talking about the Verification of Standard Methods of Inspection and Testing Institutions
Inspection and testing methods are the basis for inspection and testing institutions to carry out inspection and testing work, as well as the basis for inspection and testing institutions to allocate personnel, equipment, environmental conditions, and consumables, and are the basic guarantee for ensuring that the inspection and testing reports issued are accurate and reliable. Article 4.5.14 of RB/T214-2017 "Qualification Accreditation Capability Evaluation of Inspection and Testing Institutions - General Requirements for Inspection and Testing Institutions" stipulates that "inspection and testing methods include standard methods and non-standard methods (including self-made methods). Standard methods should be used in preference and valid versions of standards should be used. Validation should be performed before standard methods are used. Before using non-standard methods (including home-made methods), should be confirmed. Inspection and testing agencies should track changes in methods and re-verify or confirm. ”In daily inspection and testing work, most of the standard methods are used, so the verification of standard methods is an important routine work of inspection and testing institutions.
