pH & Voltage Process Calibrator PIE 235 | calibrate your pH Instruments
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.
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.
