*1 Calibrations were prepared using the most recent wood and measurement techniques. Different values are displayed for the calibrations of the 16 wood group classifications.
*2 Uses the same calibrations as our “TURKU, MT-8S, MT-700 (production of the preceding 3 products discontinued) ” wood moisture testers. Refer to p. 20 “8. Wood Group Number Table”.
*3 Range when measured at 20°C. For temperatures below 20°C, the measurable lower limit value increases by 0.1% per 1°C.
