TOOLTOP ET72 Process Calibrator – 4-20mA Loop, Voltage and Thermocouple Signal Generator
PKR 20,650.00
TOOLTOP ET72 process calibrator: measures and outputs 20mA, 30V and 100mV, 24V loop power, 8 thermocouple types. For PLC and transmitter work.
Description
The TOOLTOP ET72 is a handheld process calibrator and signal generator for industrial instrumentation. Use it to source and measure 4-20mA loop signals, DC voltage and thermocouple signals when commissioning or fault-finding PLC inputs, transmitters, valve positioners and panel meters.
It can power a two-wire loop from its own 24V supply while reading the loop current, simulate thermocouples of eight types with automatic or manual cold-junction compensation, and step or ramp its output automatically. V, mA and percentage are shown together on one screen.
Key Features
- 🔌 Measure and output 20mA DC current, including SIMULATE output for two-wire transmitters
- ⚡ Measure and output DC voltage in 100mV and 30V ranges
- 🔁 Loop check: supplies 24V loop power and measures the current at the same time
- 🌡️ Thermocouple measure and output, 8 types (R, S, B, K, E, J, T, N), ℃ and ℉, auto or manual cold-junction compensation
- 📈 Manual step and automatic waveform output; V, mA and % shown together; switch-value measurement
