Multifunctional thermometer Termex TMK-12
Multifunctional thermometer Termex TMK-12 Designed for measuring temperature and electrical signals from resistance thermometers, thermocouples and thermistors. Has 6 measuring channels and a temperature sensor included. The temperature sensor provides a measurement error of ±0.02 °C in the range from -80 to +200 °C. The following can be connected to TmK-12 as primary temperature converters: Thermocouples types A-1, A-2, A-3, B, E, J, K, L, M, N, R, S, T with standard NSX. Reference thermocouples of PPO and PRO types. Gold-platinum (Au/Pt) and platinum-palladium (Pt/Pd) thermocouples. Platinum, copper and nickel resistance thermal converters with NSCR or with individual coefficients of the HPT function, determined during their calibration. Platinum resistance thermal converters with the function of converting resistance to temperature in the form of a fourth-order polynomial with individual coefficients determined during their calibration. Reference platinum resistance thermal converters with a calibration characteristic according to MTSh‑90. NTC type thermistors with a calibration characteristic described by the Steinhart-Hart equation. Features: Large selection of NSH for temperature sensors. Convenient, free software for Windows. Optional accessories for quick and reliable connection of sensors. Benefits: Convenient, intuitive interface for controlling the device using a color display with a touchscreen. The complete sensor provides temperature measurement at the level of the 3rd category standard. Flexible independent setting of modes for each measurement channel. The modular design of the measuring part increases the speed of measurements and increases the fault tolerance of the device. The stability of metrological characteristics is ensured by sealing and thermostatting of measuring transducers. Low noise level at high measurement speed. The ability to take into account the offset of voltage and resistance input signals, as well as to offset the measured temperature. The measurement results of signals from primary converters and calculated temperature values are displayed and accessible via interfaces: USB with galvanic isolation, RS-232, RS-485 and Bluetooth. Freely distributed software allows you to observe and document measurement results in the form of graphs and tables, and calculate individual calibration characteristics of resistance thermal converters in various ways. Original terminal blocks with magnetic fastening TmK-K, extension cable TmK-KUK and docking station TmK-D for installing 6 terminal blocks allow you to quickly and reliably connect temperature sensors with plugs, fork terminals or simply bare wires. Visual video tutorials on the operation and correction of the built-in standards are available on YouTube. Manba: https://www.nv-lab.ru/catalog_info.php?ID=7470
