Best 20ma Current Source

ennoLogic Volt mA Thermocouple Loop Process Calibrator eC370T - 0-20V and 4-20mA Simulator – Portable Millivolt mA and Temperature Signal Generator and Meter for Transmitters Current Loops PLC

• VERSATILE AND ACCURATE VOLT MA THERMOCOUPLE CALIBRATOR: Signal generator, simulator and volt / mA meter for calibrating, testing and repairing milliamp loops, thermocouples, PLC, temperature control and HVAC systems. Easily generate precise test signals for current and voltage devices (mA, mV, V, Celsius and Fahrenheit ranges)..
• NUMERIC KEYPAD for ease and flexibility in setting output signals configuring options. HOTKEY programming for each numeric key (long-press immediately outputs user-configured voltage, current or temperature signal). RAMP AND LADDER OUTPUT FUNCTIONS can be custom configured. BUILT-IN 24V LOOP SUPPLY lets you power and read a device or transmitter without needing another multimeter. This greatly simplifies testing 2-wire current loops..
• MEASURE VOLTAGE OUTPUT SIGNALS from process devices and sensors with two input ranges of 0-100mV (0.01mV resolution, 0.06% accuracy) and 0-20V (1mV resolution, 0.08% accuracy). MEASURE CURRENT TRANSMITTERS within a range of 0 to 24mA with 0.001mA resolution and 0.08% accuracy. MEASURE THERMOCOUPLE TEMPERATURES within a range of -250°C to +1800°C and resolution of ±0.7°C to ±2°C (range and resolution depends on thermocouple type, supported are type K, J, E, T, N, S, R, and B.).
