Voltage Calibrator for all your process voltage signals

  • Voltage calibrator sources three ranges of mV & V dc plus percent of 1 to 5 voltsWith the 235 you can check, calibrate and measure all your voltage, millivolt and pH signal instruments in your plant. Source -500.00 to 999.00 mV, 1.000 to 5.000 V, -25.00 to +125.00% of 1 to 5 V; 0.000 to 20.000 V.
  • Power your loops with over 1,000 Ohm loadsThe 20.000 V range has an extended span of up to 24.000 Volts giving you a portable source for powering your loops.
  • Read DC voltsThe 235 can measure from -500.00 to +999.00 mV, 0.000 to 5.100 V, -25.0 to 125.0 % of 1 to 5 V; 0 to 20.000 V and 0.00 to 60.00 V DC. Use it to check loop power supplies, I/V converters, 1 to 5 Volt signals, and other voltages.
  • Save time calibrating recorders and monitors in 4 to 20 mA loopsOther brands of calibrators require that you break the loop to calibrate voltage inputs. With the PIE 235 you simply clip the test leads across the voltage inputs in a live 4 to 20 mA loop without disconnecting any wires.
  • Simulate pH probes into transmitters & analyzersUse the pH simulator to verify proper operation of pH devices before you place a probe into a calibrated buffer.
  • Quickly set any three outputs plus automatic stepping & rampingEasily set any value with the adjustable DIAL plus store any three output settings for instant recall with the EZ-CHECK switch. Choose between 2, 3, 5 & 11 steps to automatically increment output in 100%, 50%, 25% or 10% of span plus continuous ramp. Set step/ramp time to 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds.
  • Use in the Plant, Field or ShopIncludes Rubber Boot and Attached Test Leads; Low profile switches resist accidental damage
  • Simple Battery ChangesSeparate compartment for no-tool battery changes with four inexpensive “AA” batteries




Advantages of the PIE Model 235 over the Altek 235 voltage calibrator

  • Voltage calibrator has wider ranges with greater accuracy
    More than twice as accurate with 10 times greater resolution.
  • Automatic stepping
  • Larger display with backlight
    Easy viewing in dark locations
  • More Resistant to Accidental Damage
    Rubber Boot and Stronger Switches
  • Separate Battery Compartment with 4 “AA” Batteries
    No more removing housing with screwdriver to replace three expensive 9V batteries. Calibration seals remain intact.
  • Simulate a pH probe
    Calibrate pH transmitters and analyzers before attaching probe to verify that each is working correctly.
  • Includes Certificate of Calibration
    All PIE Calibrators come with a free signed and dated certificate. Altek’s come only with an unsigned Statement of Calibration Practices with a certificate of calibration available for an extra charge.
