The characteristic of our digital recorder is as follows:

1.High precision, good stability. This indicator take the microprocessor as a core, uses automatically calibrates the electric circuit. Controls by the microprocessor to the indicatoranalogous circuit partially carries on zero, the full measuring range, the cold end temperature automatic calibration, uses the precise datum constant voltage source to have the fine long-term stability. The software technology causes the indicator to guarantee the accuracy and the reliability in the widest effective survey scope.
2.The antijamming ability is strong because uses the double integral A/D switch (sampling speed 12.5/seconds), it has stronge antijamming ability to the labor frequency and the higher harmonic. In the circuit design and the production craft takes a series of measures, the measuring appliance may remove each kind of disturbance which comes from the power source, the large scale voltage undulation and the instantaneous power failure influence, can guarantee in does not need in the situation which artificial dryly gives the long-term reliable movement.
3.Using high brightness LED Digital Display
4.The function completely is advantageous for the expansion, this indicator can match the printing connection. There is a clock in the indicator, the clock is adjustable,and the indicator is equipped with nickel-cadmium battery.When the indicator normal works,the battery can be charged.When power outages, the indicator automatically maintain state from the internal battery to maintain the clock away. When the indicator placed in the fast measurement,it can automatically print the measurement time and the measurement temperature.
5.Comprehensive integrated circuits,and use the plug installment, easy to maintenance
6.The indicator has the isolation and parallel BCD code output; or the 4 ~ 20mA (1 ~ 5v) analog data output interface,for the users choice. In order to match the large screen monitor or send the measurement result to the machine.
7.On the indicator interior main engine board is equipped with a calibration number to transform the short pathway, for the user choice. Each indicator can be matched for 4 kinds of different calibration thermocouples (B, S, R, WRe or B, S, R, K).
8.The shell of the indicator is a closed structure.It can be used under the industrial scene adverse environmental conditions in a long-term reliable operation.
9.The indicator can be used for monitoring the temperature of the fast measurement and continuous measurement.
