(*1)Lithium Battery (CR-2) can be used for this unit, however the possible temperaure mesurement will be - 20 to 60°C. If you are measuring below -20°C or above 60°C, we recommend the Optional Battery Set TR-00P2 (*2)Battery Life differs depending on measurement environment and battery performance. (*3)Not for continued immersion. (*4)The water resistance rating with the sensor or input cable connected is IP64.
