China Cheap price 4-20ma Calibrator - ET2110 High-Precision Temperature Process Calibrator – Zhongchuang Detail:

1

¤ Measurement/output: voltage, millivolt, resistance, resistance, thermocouple, rtd, current, etc

¤ 220V measurement function

¤ Simulating 2-wire transmitter

¤ Resistance measurement options: 2 wires, 3 wires, 4 wires

¤ Accuracy: 0.01%, 0.02%

¤ Two isolated channels support measure and output simultaneously

¤ Providing manual step, automatic step, automatic step and manual step functions.

¤ 3.5 TFT LCD screen,resolution rate 480*320

¤ Measurement and output data can be displayed simultaneously or separately;

¤ 5000mAh Lithium battery

¤ Automatic power shutdown function, shutdown time can be set, and suitable for on-site use

¤ Providing DC 24V loop power for on -site use

¤ Thermocouple measurement and output provide three kinds of cold junction temperature compensation methods: built-in, external and manual, among them, external reference junction adopts A class Pt100 Platinum resistance, which can correct temperature through inputting certificate value

¤ Thermocouple types: R,S,K,E,J,T,N,B,L,U,XK,WRE325,WRE526;

¤ RTDtypes:PT100-385,PT100-392,PT100-JIS,PT200-385,PT500-385,PT1000-385,Cu10,Cu50,Cu100,Nil20,BA1,BA2,PT10;

¤ Temperature difference measurement function: the accuracy is up to 0.003℃. This product can measure the temperature difference between two points in the space, and complete a temperature difference data collection within 0.4 seconds, effectively improving the measurement accuracy.The 10-minute fluctuation during the test can be calculated in real time.Before using standard platinum resistance or standard thermocouple for measuring work, the measurement results can be traced through the input of certificate value, and meet the requirements of the thermostatic tank test specification for electrical measuring instruments.

¤ Standard temperature measurement function: Comparing with common thermocouple measurement and RTD measurement,the difference is that  this measurement method can trace the temperature by certificate value,the supported standard thremocouple and RTD are as followed: S、R、B、T, Pt25、Pt100 

¤ Arbitrary sensor’s measurement function; Users can transform the measured physical quantity(Pressure, flow speed, temperature,etc) to voltage, current, resistance,etc conveniently for measurement. Besides, Users only need to input the response curve in advance, and the multimeter will adopt the internal algorithm for numerical conversion and correction, and finally the measured physical quantity will be displayed on the screen.You are free to edit and modify the display units of the measured physical quantities.

¤ Precision temperature control function; Precision temperature control function will realize the temperature closed-loop control of thermostatic equipment, which replace the high precision PID controller.Under the condition of thermostatic equipment and network voltage,temperature fluctuation will be better than 0.02℃/10min (Thermostatic Bath)

¤ Measurement function of ρ’s value: can measure duty ratio of periodic square wave signal; verify and calibrate the PID parameter of Various digital temperature indicating regulators which is outputted by time scale,and conform to the requirement of 《JJG617-1996 digital temperature indicating regulators》

¤ Thermal Conversion Function: realize the conversion between various electric quantity and temperature.The types of electric quantity and temperature conversion include: working thermocouple, industrial rtd and various temperature transmitter.

¤ Numerical setting mode:its with the most flexible and convenient way to set output value; User can use the numerical keyboard to set output value directly, and can realize the incremental setting by direction key. In addition, the equipment also has a step or ramp numerical setting mode that can be numbered.

¤ Sinusoidal output function: The verification/calibration of some process logger (especially mechanical logger); Usually It involves running test, and it can provide signals to the measured table by using sinusoidal output mode.

¤ Data Record Function:  with powerful record management function, it can establish up to 32 device numbers. Each device number has 16 record pages, and each record page contains four basic information: time, measured value, output value and custom value.Users can carry out equipment management, record deletion and other operations according to requirements.
