How to use
Place the thermometer probe inside the aquarium at a representative location away from direct heater output or strong water flow to obtain an accurate average temperature. Ensure the unit is fully submerged as specified by the manufacturer and position the display where it is visible for routine checks. Periodically verify readings against a secondary thermometer when calibrating equipment or after maintenance. Rinse the probe with aquarium water during regular tank maintenance; avoid using harsh chemicals on the sealed housing.
Usage recommendations
For consistent results, position the probe near the middle of the water column and away from equipment that causes localized heating or cooling. Cross-check the digital reading with another reliable thermometer after significant equipment changes, and clean the probe gently during routine maintenance to prevent biofilm buildup that may affect response time.
