    Why temperature continues to rise when not expected in Grant Laboratory Equipment?

      Justin CookAug 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.
