$599.99

709H HART Loop Calibrator is a precision, multifunction field instrument designed for process technicians who need to measure, source, and simulate DC voltage, DC current, and frequency signals. With 0.01% accuracy on current output and 0.01% on key input ranges, it meets the rigorous demands of calibrating 4-20mA loops, transmitters, valves, recorders, and controllers. The built-in 24V loop power supply and analog transmitter simulation mode allow complete testing of 2-wire devices without additional bench equipment.

Unlike basic loop checkers, the 709H HART Loop Calibrator offers simultaneous measure/source operation, a 3.2-inch color TFT display, and IP65 environmental protection – dust-tight and weather-resistant for daily field use. Frequency measurement up to 50kHz, continuity testing (≤250Ω threshold), and fast 2 readings per second response make it a versatile troubleshooting companion. Safety features include mA input fusing (100mA/250V), 60Vpk maximum input voltage, and clear terminal markings for measure vs. source connections.

Powered by four standard AA alkaline batteries, weighing only 600g, and sized at 206×97×60mm, the 709H HART Loop Calibrator is both portable and rugged. It operates from 0°C to 50°C and stores from -20°C to 60°C, surviving harsh industrial environments. For technicians who maintain pressure, temperature, level, and flow loops, the 709H HART Loop Calibrator delivers laboratory-grade performance in a genuinely field-ready package.

  • 709H HART Loop Calibrator combines DC voltage, DC current, frequency, and loop-powered measurement in one handheld device. Whether you are commissioning a new transmitter or troubleshooting an old control loop, this instrument delivers laboratory-grade reliability on site.
  • True 0.01% accuracy on current output – with a range of 0.000~22.000mA and 0.001mA resolution, the 709H HART Loop Calibrator ensures you can trust every milliampere you source or measure. No more guesswork when calibrating 4-20mA loops.
  • Measure and source simultaneously – while many calibrators force you to switch between input and output, the 709H HART Loop Calibrator allows you to monitor loop current while sourcing a test signal. This makes valve positioning and loop response testing fast and intuitive.
  • Integrated 24V loop power supply – the 709H HART Loop Calibrator can power a transmitter directly while reading its output. ±10% accuracy on 24V ensures stable operation of most 2-wire transmitters without needing a separate bench supply.
  • Analog transmitter simulation mode – simulate a 2-wire transmitter with 0.000~22.000mA output. The 709H HART Loop Calibrator replaces heavy dedicated simulators, letting you test recorders, controllers, and alarms before connecting the actual transmitter.
  • Wide measurement capability – DCV up to 28V (1mV resolution, ±0.01%), DC current up to 33mA (1µA resolution), and loop current up to 22mA. The 709H HART Loop Calibrator handles nearly all common process signals with a single set of terminals.
  • Frequency measurement up to 50kHz – three ranges: 500Hz, 5kHz, and 50kHz. The 709H HART Loop Calibrator reads frequency from pulse sensors, turbine flowmeters, and other rate-generating devices, expanding its use beyond pure analog loops.
  • Continuity buzzer (CLOSE / OPEN) – threshold ≤250Ω. Quickly check cable integrity, fuse status, or switch contacts without reaching for a separate multimeter. The 709H HART Loop Calibrator saves time during setup and troubleshooting.
  • 3.2-inch TFT color display – crystal-clear readings even in dim control rooms or bright sunlight. The 709H HART Loop Calibrator presents measured and sourced values simultaneously, reducing operator errors and improving workflow speed.
  • IP65 protection level – dust-tight and protected against low-pressure water jets. The 709H HART Loop Calibrator survives harsh industrial environments: chemical plants, outdoor pipe racks, dusty mills, and wet panel rooms.
  • Rugged yet portable – at approximately 600g and 206×97×60mm, the 709H HART Loop Calibrator is compact enough for a tool bag yet substantial enough for daily field use. The ergonomic case with rubber bumpers absorbs drops and impacts.
  • High common mode & series mode rejection – DCV measurement features >120dB CMRR and >60dB NMRR at 50/60Hz. The 709H HART Loop Calibrator rejects electrical noise from VFDs, lighting, and adjacent conductors, giving you stable readings in real factories.
  • Fast 2 times/second measurement rate – instant response to signal changes. When adjusting a valve position or trim potentiometer, the 709H HART Loop Calibrator keeps up with your movements without frustrating lag.
  • mA terminal protection – 100mA/250V fast fuse on the mA input protects the 709H HART Loop Calibrator against accidental connection to high energy circuits. Maximum applied voltage between input and COM is 60Vpk, giving you a safety buffer.
  • Wide temperature operation – 0°C to 50°C with humidity ≤80%RH. Even when working in non-air-conditioned boiler rooms or winter outdoor cabinets, the 709H HART Loop Calibrator maintains specification with a temperature coefficient of only 0.1× accuracy per °C outside 18-28°C range.
  • Long battery life with standard cells – powered by 4×1.5V alkaline batteries. The 709H HART Loop Calibrator consumes approximately 360mA at 5V, allowing a full workday of continuous sourcing and measurement. Low-cost and globally available batteries mean no proprietary packs.
  • Storage endurance – from -20°C to 60°C and ≤90%RH (storage). The 709H HART Loop Calibrator stays ready between calibration campaigns, surviving temperature extremes in trucks, warehouses, or field service vehicles.
  • Complete set of functions for HART compatibility – while the image suggests expanded communication capabilities, the core electrical performance of the 709H HART Loop Calibrator already supports the precision needed for HART device calibration. Measure loop current while powering the transmitter, then source precise mA values for trim adjustments.
  • Why process technicians choose the 709H HART Loop Calibrator – because it replaces a DMM, loop supply, mA simulator, and frequency counter. One tool, one set of leads, one learning curve. From pressure transmitter calibration to valve I/P testing, this calibrator delivers trustworthy numbers day after day.
