Checkline TI-UMX2 Underwater Ultrasonic Thickness Gauge with datalogging
Range:0.025 - 9.999 inches - 0.63 - 254.0 mm
Resolution: .001" (0.01 mm)
Rated for dive depths up to 1000 ft (300 meters)
Measuring Range in Steel
The Checkline TI-UMX2 Underwater Wall Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals at depths of up to 1000 feet (300 Meters). Also measures Coating Thickness.
A back-lit LCD display and illuminated housing allow divers to easily read measurements in dark water.
An over-sized control button and clever menu structure allows easy gauge setup and navigation through menus above or below water even when wearing thick gloves.
The TI-UMX-2 can store up to 5000 readings including A-Scan Waveforms and settings for each individual measurement. There are 2 file structure options; sequential with auto identifier and alpha numeric grid (row/column) format. The UMX-2 can transfer data and configuration settings to a PC using our DataComm software. (Software and transfer cable included)
