Description: 
 Ultrasonic thickness gauge with high sensitivity, good stability, reliable, simple operation, low power, compact, intelligent instruments, widely used in electric power, petroleum, chemical, metallurgy, machinery, ships and other departments to detect pipes, boilers and pressure vessel wall thickness, is the safe operation of equipment protection. 
 Technical parameters and characteristics: 

 Model Resolution (mm) through the coating function measurement range (mm) probe selection function indication error 
 UM-1 0.1 None 0.8 ~ 300mm ± 0.1mm (25mm less) 
 ± 1% H +0.1 (25mm or more) (H: the measured height) without built-in probe selection, the normal standard for PT-08 probe configure other probe, the instrument to the factory settings. 
 UM-1D 0.1 penetrable coating 0.8 ~ 300mm (standard mode) 3 ~ 18mm (coated model) ± 0.1mm (25mm less) 
 ± 1% H +0.1 (25mm or more) (H: the measured height) without built-in probe selection, the normal standard PT-08 probe, for configure other probe, the instrument factory to be set, but the configuration of other probe through the coating function is not available. 
 UM-2 0.01, 0.1 no 0.8 ~ 300mm ± 0.05mm (10mm less) 
 ± 0.5% H +0.01 (10mm or more) (H: the measured height) built-in seven probe selection function (PT-08, PT-06, PT-04, PT-12, ZT-12, 5P-10, GT-12,) the normal standard PT-08 probe. 
 UM-2D 0.01, 0.1 penetrable coating 0.8 ~ 300mm (standard mode) 3 ~ 18mm (coated model) ± 0.05mm (10mm less) 
 ± 0.5% H +0.01 (10mm or more) (H: the measured height) built-in seven probe selection function (PT-08, PT-06, PT-04, PT-12, ZT-12, 5P-10, GT-12,) the normal standard PT-08 probe, the choice of standard probes except the probe other than the feature is not available through the coating.
