TES PROVA-135 4-20mA Loop Calibrator + Thermometer

  • Source 4~20mA, 0~24mA with 1μA resolution (1KΩ load, 24V loop supply), basic accuracy 0.025%.
  • Source 0~24.000V with 1mV resolution. Source frequency 1~20000Hz square wave with programmable duty cycle (1~99%).
  • Auto step and auto ramp for sourcing mA, V.
  • Easy fixed 25% up and down, or
  • programmable percentage (1~99%) increase and decrease (mA, V).
  • Measure DC mA with loop power (24V output).
  • Measure DC V.
  • Measure Temperature (°C, °F) of 11 types of thermocouples (K, J, E, T, R, S, N, L, U, B and C).
  • Calibrator grade precision temperature measurement with 0.1*C & 0.1*F resolution.
  • Detection of thermocouples disconnection. Source and Measure at the same time.
  • Warning for overload, output open (mA) or short (V).
  • Short circuit protection for output.
  • Battery power indication (%) when turn on the calibrator.

Applications:

  • Calibration of 4~20mA panel meters. LED brightness testing (0~24mA).
  • Temperature calibration of panel meters or instruments for 11 types of thermocouples.
