ETX-2028 type multifunction calibrator ETX2028
Product features:
▲ the Chinese LCD interface and intelligent operating system perfect, make the instrument more humane.
▲ V, mV, mA, (TC) Ω and thermocouple, thermal resistance (RTD) output and the measured signal. 24V DC distribution output circuit to provide power for the transmitter, and can simultaneously measure the transmitter output values of mA
▲ with frequency (Hz) measurement and simulation function.
▲ full digital operation, intelligent menu prompt; more intuitive and easier to use, handy.
▲ type thermocouple (resistance) ℃ value, display and output the corresponding mV (Ω) value, no need to check the indexing table
▲ measuring thermocouple (resistance) signal, anddisplay mV (Ω) value
▲ using high precision temperature sensor provides the cold end compensation for thermocouple.
▲ all signals can fine tune or continuous increase or decrease in arbitrary number.
▲ with analog transmitter function, can check DCS channel 4 ~ 20mA current loop.
▲ has RS232 communication interface, to achieve rapidcorrection of instrument error by PC.
▲ AC-DC dual-use, built-in large capacity and high performance imported rechargeable lithium battery, a charge more than 8 hours of continuous work, visualinstrument working state change.
▲ imported chassis, beautiful and durable.
▲ dimensions: 250 x 200 x 85 (mm) weight: 1Kg
