PIE 235 pH and Voltage Process Calibrator

Practical Instrument Electronics 235 Includes Only:

• Four "AA" Alkaline batteries, NIST Traceable Calibration Card Black Rubber Boot
• Evolution Hands-Free Carrying Case
• Evolution mA/V Test Leads
• 1 Red and 1 Black Lead with Banana Plugs and Alligator Clips

Features:

• Voltage calibrator sources 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, -25.00 to +125.00% 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 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 loops. Other brands of calibrators require that you break the loop to calibrate voltage inputs. With the Practical Instrument Electronics 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 and 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 and ramping. Easily 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, and 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.
• Simple Battery Changes. Separate compartment for no-tool battery changes with four inexpensive"AA" batteries.
