The LT-300 thermometer is intended to replace precision mercury thermometers

PC cable and Windows software is included

Temperature range −50...+300 °C

Resolution 0.01 °C, accuracy ±0.05 °C

The LT-300 thermometer may be used anywhere a glass thermometer or other type thermometer usually used

The LT-300 incorporates glass thermometer simplicity with the ease of a digital display. Like precision mercury thermometers, the LT-300 has accuracy, repeatability and long-term stability. But unlike those thermometers it is hard to break it down and there will never be problems with hazardous material cleanup

Unlike most electronic thermometers, the battery powered LT-300 has no wires to get in the way. Due to low power consumption the LT-300 can be operated for about a year on one set of two AAA batteries

Low battery display, and failure mode indications protect the user from false data

Two years warranty
