How do you disable high limit?

The high alarm limit cannot be disabled independently from the low alarm. You can either switch the alarm function off, or set the high limit to its maximum value to avoid nuisance alarms.

What is temperature range?

Mine has registered as low as -23. We call this our blast freezer cuz it gets so cold. We also tried both units on it and they were the same temp.

Are probes water proof for use in aquarium? Does unit continue to alarm until reset manually?

The manual claims that the sensor probe is waterproof. The alarm only sounds audibly while the temperature is outside the alarm limits. It shuts off the alarm tone when the temperature returns to normal. You can use the min/max feature to check for any temperature excursions since the last time the min/max values were reset.

Does the probe have an alarm that I can set? Or is the alarm only for the external part that shows the temperatures ?

You can set your own high and low alarm values in Celsius or Fahrenheit. The alarm only applies to the external sensor probe, not to the main display unit. If the probe temperature goes outside your alarm limits the main unit will give an audible chirp but it will stop sounding once the temperature returns to its normal range. You can also use the min/max feature to see if there were any temperature excursions since the last time the min/max values were reset.
