Our thermometers provide a triple display that simultaneously shows current and high and low temperatures. A minimum and maximum memory feature permits monitoring conditions overnight, weekends or any time period. Units can also read ambient or probe temperature. The 1/2-high digital display is easy to read and instantly shows if your water bath, refrigerator, freezer or incubator is within your temperature specification. The 10-long cable and sensor perform accurately, even when under water. The temperature range is from - 58° to +158°F and -50° to +70°C with resolution to 1° and accuracy of ±1°. The alarm sounds when the temperature rises above or falls below the programmable setpoints and continues to sound for up to 12 hours, even if temperature returns to the nonalarm range. You can set the alarm in 1 degree increments.
