BulletPoint1 : AT4756 multi-channel temperature tester with high-performance ARM microprocessor control, 7-inch color LCD display, touch screen operation, easy to view temperature values, temperature changes Curves, histograms, etc., can collect multi-channel temperature data at the same time, super-super alarm and communication transmission, compatible with K/N/E/J/T/R/S/B Type thermocouple, fast response, stable data, and fault detection. Each channel can be set individually and independently corrected.
BulletPoint2 : The instrument supports RS-232 communication, and data acquisition, analysis and printing can be realized through the standard computer software. Support USB disk storage for real-time storage of sampled data. Users can independently correct each data.
BulletPoint3 : The AT47 series uses fully isolated digital and analog signals, ## (can be tested for live (isolated voltage 230V rms, 330VDC), safe and reliable.
BulletPoint4 : The instrument has built-in RS-232C interface and USB-232 interface. The instrument is equipped with universal data acquisition software, self-contained database function and Excel export function, which can be effectively used for remote control and data acquisition and analysis. The instrument uses Amber Instruments to enhance the computer remote control instruction set, compatible with SCPI (Standard Command for Programmable Instrument programmable instrument standard command set) and Modbus
