This max/min alarm thermometer simultaneously displays the actual temperature whilst displaying the maximum and minimum temperatures.


The indoor/outdoor thermometer measures the grow room (in) temperature over the range of 0 to 49.9°C using the unit's internal sensor. Utilising the remote external temperature sensor the unit measures nutrient tanks and similar over the range of -49.9 to 69.9°C.


This thermometer features a programmable hi/low temperature alarm that will sound when the pre-set limits have been exceeded, making this instrument ideal for monitoring growing cabinets.


The thermometer is housed in an ABS case, measuring 20 x 65 x 97mm, that incorporates a useful foldaway stand and a keyhole slot for hanging on a wall.
