Power Supply: One lithium battery, CR2450 (coin size)
Battery Life: Approx. half month of continuous use
Environmental Requirements: Temperature 0 to +45°C, Relative Humidity up to 90% (non-condensing)
Dimensions: Approximately 1.2”W x 5.7”H x 0.5”D excluding the clip.
Weight: Approximately 1.75 oz.
*The measured value is stored unless the battery is removed or the power switch is pressed for ten seconds when turning on the instrument.
Note: As an attempt to verify operation or accuracy, never irradiate the dosimeter directly to a source such as X-ray as it is not designed for exposures in locations where doserate is 100 mSv/h or more. For questions concerning calibration or repair, please call 1-800-497-2071. It is recommended by the manufacturer that dosimeters should be tested for accuracy on an annual basis by a qualified lab. Units failing to meet specifications cannot be repaired or re-calibrated.
