Glucometer with high-precision measurement function

The utility model discloses a glucometer with a high-precision measurement function. The glucometer comprises a shell and a thermistor arranged on the shell, a PCB is arranged in the shell, and the thermistor is connected with the PCB. A blood glucose testing module is arranged on the PCB; the glucometer also comprises a first heat insulation sheet; the first heat insulation sheet is arranged on one side of the blood glucose testing module in a surrounding mode. The beneficial effects of the utility model are that the blood glucose test module is placed in the cavity formed by the first heat insulation sheet and the second heat insulation sheet, so that heat generated by the blood glucose test module is insulated, and the temperature of the blood glucose test module is prevented from affecting the measurement result of the thermistor; therefore, the ambient temperature detected by the thermistor is consistent with the actual ambient temperature, and the glucometer adjusts the resistance value according to the
