Purpose of the development: For remote high-precision temperature measurement.

Recommended application field: In metrology, in scientific research.

Technical characteristic: The measurement process - automatic. Measurement time - not more than 1 second. Issuance of measurements - on the thermometer display screen and the PC (time reference). Resistance measurement range from 0.00001 to 340 ohms. Graduation 10-4 degrees. Connect the measurement object - four clamping. Limit values relative multiplicative error calculation formula and limits the relative error of the additive are given in the table (at least 5 seconds, to measure the time). RX, Ohm - 0.00001 ... 340. CRN,% - CRN (140 / Rx). 0RN,% - 0,002. CRN,% 0,00004. The distinction (threshold), Ohm - 0.00001. Crn - limit (the boundary interval) the above additive error; Rx - the value of the measured resistance in ohms; The device provides a calibration mode for Foreign least resistance. The thermometer provides complete software, allowing for the display of measurement results, and save the information in the files. At the same time the PC connects to the thermometer via a serial interface (RS232 or RS485). Meals thermometer - the built-in power supply. The power consumed from the network with a thermometer, not more than 5 VA. Weight of the device - not more than 1 kg. Dimensions - 310x120x270 mm. MTBF - not less than 10000 hours. Full average life bulb life - not less than 6 years.

The development stage readiness: Ready for application
