TECPEL CL420A : Process Calibrator 4-20mA. Provides DC 24V loop voltage, and measure current at the same time, and perform switch on and off measurement.
Features:
- 5 digits display.
- DC Voltage output (DCV) : 24 V. (+/- 10%)
- DC Current Loop Output (DCA) : 0.100mA to 22.00 mA (+/- 0.05% + 4 uA)
- DC Voltage measurement: +/- 0.100 to 28.00 V. (+/- 0.02% + 2 mV)
- DC Current measurement: +/- 0.001mA to 20.000 mA. (+/- 0.02% + 4 uA)
Description
The CL-420A is a handheld programmable calibrator for measurement and signal output. Its great for measuring tiny currents and voltage signals, and it can power sensors while checking their returned current signals. Mainly used in sensor testing and monitoring gear, like for humidity, water level, wind speed, pressure, and other sensors and monitors. Definitely a must-have tool for engineers and technicians servicing sensor equipment.
