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. Adjusting the

pH transmitter or analyzer without a probe allows you to make

sure the device is calibrated and operating correctly. The

820-ELITE simulates 0.000 to 14.000 pH @ 25°C corresponding

to 414.12 to -414.12 mV.

Once the pH instrument has been adjusted against the PIE

820-ELITE reconnect the pH probe and check it against the

proper buffer (typically 7 pH). If the instrument zero point

requires more than the manufacturer’s recommendations

(typically within 0.5 pH) it is time to clean or replace the probe.
