Product Name: CMMY tonometer 
 Details: 
 Features: CMMY tonometer applies to all types of screen version of the tension test, the pointer indicate tension (unit: N), without any power. TETKOMA can easily detect the tension on the taut mesh anywhere, and the tension meter general test the network version of the radial and latitudinal tension, the screen to reach the diameter, the weft direction. Whether the new stretch screen system or reuse old version, TETKOMAT can provide reliable data on the tension test. TETKOMAT is a precision measuring instruments, in order to obtain long-term measurement results need to be kept in a clean, dry environment. Measurements on dust and dirt will cause inaccurate measurements. Second, the technical parameters: measuring principle: precision machinery measuring instruments of tension in the Web version. Display error: full scale precision error of +5% of the units: N / cm (N / cm). Measuring range :7-50 (5-60) N / cm. Net weight: 500 g Gross Weight: about 1kg net size: 108X76X44mm boxing size: 229X200X76mm spare parts: standard calibration glass. Note: The side shock, after use.
