INSTRUMENT:
Handheld pH Meter
MODEL:
-
Pro10 Meter (6050010)
-
Cable (60510-1)
-
pH Probe (1001)
-
or for mobile laboratory applications cable + probe kit (1007)
MANUFACTURER:
Yellow Springs Instrument Co., Inc. (YSI)
PRECAUTIONS:
POTENTIAL INTERFERENCES
General –
-
Greatest accuracy is achieved if the actual samples to be measured are within 10 ˚C of the
Calibration solutions.
-
Longer cable lengths introduce more error into the readings.
pH –
-
Do not measure pH in metal containers.
-
Water currents in streams can cause unstable readings.
-
pH measurements will drift if the sample is not stirred.
-
Do not expose the meter or probe to freezing temperatures.

Otherwise, remove the old sensor by unscrewing it from the bulkhead. Ensure both the sensor connector and bulkhead connector are clean and dry.

- Page 6 IOP 007E.2 Effective Date: 2/02/2018 Page 6 of 8 Wait at least 5 minutes for the pH sensor to stabilize and for the temperature reading to stabilize. Note the pH mV reading. pH mVs in buffer 4 should be +159 to 180 mV from the previous buffer 7 pH mV value. pH mVs in buffer 10 should be -159 to 180 mV from the previous buffer 7 pH mV value.
- Page 7 IOP 007E.2 Effective Date: 2/02/2018 Page 7 of 8 Place the probe in the sample to be measured. Be sure the sensors are completely submerged in the sample (note that the temperature sensor is at the top of the pH sensor). Give the probe a quick shake to release any air bubbles.
