PIE 235 Process Voltage Calibrator

Technician friendly operation

Intuitive  EZ-DIAL  Double Click Menu  makes  it  easier to setup  than other  calibrators.  Turn  on  the  backlight  to easily see  the  display  in dark areas of the plant. Connections diagrams are indicated on the display for each function along with a labeled connector panel on the top.

Calibrate with Confidence 

Accurate to ±0.02% of Reading + 0.01% Full Scale. Out of range or over current is indicated by an audible alarm, flashing display and the OVERLOAD LED will light.

Source three ranges of mV & V dc plus percent of 1 to 5 volts

With 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,  0.0  to  100.0%  of  1  to  5 V;  0.000  to 20.000 V.

Power your loops with over 1,000 Ohm loads

The  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 volts

The 235 can measure from -500.00 to +999.00 mV,  0.000 to 5.100 V, 0.0 to 100.0 % 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 loops

Other 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 & analyzers

Use 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 & ramping

Easily  set  any  value  with  the  adjustable  “DIAL”  plus  store  any  three  output  settings  for  instant recall with the EZ-CHECK™ switch. 2, 3, 5 & 11 steps 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.

Designed for you by experienced calibrator manufacturers

PIE Calibrators are designed and built by members of the same team that designed and built the calibrators manufactured by Fluke* under the Altek* label. The 235 improves upon other brands by including a rubber boot, backlit display with larger digits, higher accuracy and more ranges for flexibility.

Advantages of the PIE Model 235 over the Altek 235

•  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 PIECAL 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.
