What to do if the sample volume is not correct in my Hach Recording Equipment?
- C
  Christopher SingletonAug 2, 2025
  If the sample volume of your Hach Recording Equipment is not correct, several factors could be at play. First, repeat the volume calibration process. Ensure that the correct tube length is specified in the sampler program. Make sure the intake tube is as vertical and short as possible to ensure complete purging. If the strainer is not fully submerged, consider installing a shallow depth strainer. Replace any worn pump tubing or roller assembly. If the liquid sensor is disabled, turn it on and perform a volume calibration. If the liquid sensor isn't operating correctly, calibrate it using the same liquid being sampled.

  If your Hach Recording Equipment's battery life is short, ensure the lead-acid battery holds between 12.6 V and 13.4 V when fully charged, and replace it if necessary. Fully charge the battery and let it stand for an hour; if the voltage drops below 12.5 V, replace the battery. Also, ensure the correct portable base is selected.

  If your Hach Recording Equipment has no instrument power with DC, the battery may not be charged or may not hold a charge, so replace the battery or use an AC power cord. If neither of these actions resolves the issue, the controller may be defective, and you should contact technical support.

  Lisa Pena MDAug 27, 2025
  If the sampler on your Hach Recording Equipment does not have sufficient lift, ensure the strainer is completely submerged; if not, install the shallow depth strainer. Check for leaks in the intake tube and replace it if necessary. Also, examine the pump tube for wear and replace it if needed. If the pump roller assembly is worn, contact technical support.
