Check battery voltage before the charge and after overnight charge. Your right about the 8 volt charger. You can use an automotive charger but will have to watch that it does not overcharge the battery. The 12 volts on 8 volt will charge it, but the best would be a 24 volt charger, where you could charge 3 at a time.
A high accuracy electronic cold junction compensation circuit maintains typical system accuracy of Â±0.2Â°C over an ambient temperature range of 15 to 35Â°C. Individual offsets may be added to each input in software to facilitate individual calibration of each channel. For information on our wide selection of Type T Thermocouple temperature probes.
A rectal temperature is generally considered to be the most accurate, and the standard for monitoring the core body temperature, but it is generally not recommended for use in patients, due to the risk of rectal perforation and tears with this method. Have a separate thermometer to use for oral than for rectal.
