Why temperature continues to rise when not expected in Grant Laboratory Equipment?
- B
  Brandon HernandezAug 10, 2025
  If the temperature continues to rise unexpectedly in your Grant Laboratory Equipment, it may be because the set temperature is higher than the liquid temperature. Ensure the bath set temperature is correct. Alternatively, the set temperature might be too close to the ambient temperature. In this case, increase the set temperature, keeping in mind that the minimum temperature should be 5°C above ambient.
