Hi-Lo Thermometers with 1 Resolution - The triple display simultaneously shows high, low, and current temperatures while the min/max memory monitors high/low readings overnight, on weekends, or for any time period - a significant advantage over "current reading-only" glass thermometers. An alarm alerts you when the temperature rises above or falls below a set point and is programmable in 1 increments. Visual and audible signals continue even if temperature returns to non-alarm range. The 10-foot long micro-cable permits refrigerator doors to close on it without affecting the seal.
