What does it mean when the screen flashes during calibration of Hach H160G?
- T
  Tammy JonesAug 21, 2025
  A flashing screen during calibration of your Hach Measuring Instruments can be due to several reasons. The probe sensor surfaces may be dirty or need reconditioning, so clean and condition the probe again. Another cause could be no flow in the reference junction, so clean the warm buffer. Also, the buffers might be contaminated or expired, so recalibrate with new buffers. Interference from other devices or direct sunlight can also cause this issue, so remove all devices from the solution and protect the probe from sunlight. Finally, a low battery can cause the screen to flash, so replace the batteries if the battery icon indicates low power or the probe is too old and needs replacement.

What to do if my Hach H160G Measuring Instruments show an unstable reading?
- J
  Jocelyn HoodAug 23, 2025
  If you are experiencing unstable readings with your Hach Measuring Instruments, several factors could be the cause. First, the probe might be dirty, so try cleaning it. Also, make sure to clean the probe contacts on the cable connector and the meter using methanol on a cotton swab, letting it dry completely before reconnecting. Other potential issues include no flow in the reference junction (clean the warm buffer), an ISFET probe that isn't correctly hydrated (soak it in pH 7.00 buffer for at least 5 minutes), interference from other devices (remove them), or direct sunlight (shield the probe). Note that stable readings may not be possible in very low ionic strength solutions or if the pH or temperature of the solution is changing.

What does E14 error mean on Hach H160G?
- T
  Tyler MartinAug 25, 2025
  Error E14 on your Hach Measuring Instruments indicates that the battery is extremely low. Replace the batteries immediately to prevent potential damage to the accuracy and function of the meter.

How to fix a Hach H160G with no display?
- P
  Preston HintonAug 28, 2025
  If your Hach Measuring Instruments have no display, it could be due to a couple of reasons. First, check if the automatic shutdown feature has turned the power off; if so, simply set the power back to on. If that's not the issue, the problem might be a lack of power, in which case you should replace the batteries.

What does E04 error mean on Hach H160G Measuring Instruments?
- T
  Thomas HendricksAug 29, 2025
  Error E04 indicates a glass pH probe slope error, meaning the slope is smaller than 85% or larger than 102% of 59.16 mV per pH unit. Clean the probe. If the error continues, replace the probe.

What does E06 error mean on Hach H160G?
- B
  bonniemcconnellAug 31, 2025
  Error E06 indicates an ISFET pH probe slope error. Clean the probe, soak it in 40 ºC (113 ºF) pH 7.00 buffer for 2 minutes, and calibrate again. If the error continues, replace the probe.

What does E08 error mean on Hach H160G?
- W
  William GreenSep 2, 2025
  Error E08 means it is taking too long to calibrate, and the signal is not stable during calibration. Clean the probe. Disconnect stirrers and other AC power sources. Make sure that the calibration solution temperature is constant. Replace the probe if the error continues.

What does E25 error mean on Hach H160G?
- C
  Casey HamiltonSep 3, 2025
  Error E25 indicates that the slope is smaller than 60% or larger than 140% of the nominal. Replace the DO probe membrane and fill solution. Replace the probe if the error continues.

What does E26 error mean on Hach H160G Measuring Instruments?
- A
  Amy BlanchardSep 5, 2025
  Error E26 indicates that the mV reading is more than ±10 mV from nominal. Replace the DO probe membrane and fill solution. Replace the probe if the error continues.

What does E27 error mean on Hach Measuring Instruments?
- T
  thompsonkaraSep 6, 2025
  Error E27 indicates a DO probe temperature error. Attach the temperature sensor to the 3.5 mm phono jack. DO readings are highly temperature dependent, and a temperature sensor must be attached.
