Double your productivity or cut your calibration time in half
  • Temperatures from –15 °C to 350 °C in one unit
  • Two wells in each block for simultaneous comparison calibrations
  • Rugged, lightweight, water-resistant enclosure
You’ve been asking for it and now we’re making it for you. Hart’s new Model 9009 Industrial Dual-Block Calibrator lets you calibrate at hot and cold temperatures at the same time. Double your productivity or cut your calibration time in half—either way you look at it, your in-field temperature calibrations just got easier.


  • Rugged, compact, easy to use stroboscope for checking the rotating speed of machinery without physical contact or the need for reflective tape
  • Features high-intensity 7-LED array—4,800 Lux @ 6,000 FPM/30cm
  • Provides a high-efficiency LED solid-state light source with uniform flash characteristics that allow for higher flash rates—30-300,000 FPM (flashes per minute)


  • Optional magnetic hanger for easy set-up and viewing while freeing your hands for other tasks
  • Large digit display with bright, two-level backlight makes the 83V significantly easier to read than older models
  • 6000 counts, 3-3/4 digits
  • Measure up to 1000 V AC and DC
  • Measure up to 10 A, 20 A for up to 30 seconds
  • Frequency to 200 kHz and % duty cycle
  • Resistance, continuity and diode test
  • 10,000 µF capacitance range for components and motor caps
  • Min/Max-Average recording with Min/Max Alert to capture variations automatically
  • Relative mode to remove test lead interference from low ohms measurements
  • Auto and manual ranging for maximum flexibility
  • Touch Hold to capture stable readings avoiding noisy signals
  • Large display digits and two-level bright white backlight for increased visibility
  • Analog bargraph for fast changing or unstable signals
  • Input Alert provides audible warning against wrong use of input jacks
  • Improved selectable sleep mode for long battery life
  • Access door for fast battery changes without breaking the calibration seal
  • "Classic" design with new removable holster with built in test lead and probe storage
  • Lifetime warranty
Electrical safety
All inputs are updated to the 3rd edition of ANSI/ISA S82.01 and EN61010-1 CAT IV 600 V and CAT III, 1000 V. They can withstand impulses in excess of 8.000 V and reduce risks related to surges and spikes.
  • Measure AC current with an optional current clamp accessory


Solve power problems you meet in your daily work, now that electrical loads in industrial and commercial buildings are often too complex to be calculated by the classical model of power.
Understand the major elements that affect power quality with our online webcast and supporting guidebook:
  • particularly inductive loads
  • harmonic distortion
  • three-phase power unbalance


  • Ergonomic handle that adapts to user’s hand, causes less strain and work fatigue and provides maximum torque.
  • Full length, impact proof handle core is coated with soft-grip outer material, hanging hole for extra security, and anti-roll handle design.
  • Slim insulated shaft allows access in hard to reach areas.
  • Certified to 1000 V ac, 1500 V dc
  • Two sizes (Phillips #1 and Phillips #2), sold individually, also in kits
