Why are the readings unstable on my TPS pH Cube?
- SScott RomeroAug 21, 2025
Unstable readings on your TPS Measuring Instruments can occur due to several reasons: * A blocked reference junction: Clean the reference junction as per the instructions supplied with the sensor. * A dirty glass bulb: Clean the glass bulb as per the instructions supplied with the sensor. * A bubble in the glass bulb: Flick the sensor to remove the bubble. * A faulty connection to the meter: Check the connectors and replace if necessary. * The reference junction not being immersed: Ensure that the bulb AND the reference junction are fully immersed. * KCl crystals around the reference junction, inside the electrolyte chamber: Rinse the electrolyte chamber with warm distilled water until dissolved.
