The MODEL 235 process Voltage & pH Calibrator from Practical Instrument Electronics (PIE), allows you to check, calibrate and measure all your voltage, millivolt and pH signal instruments in your plant, from just one pocket sized unit.
Source three ranges of mV & V dc plus percent of 1 to 5 volts
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
The 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 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-CHECKTM 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.
