Used for measuring thickness and corrosion of pressure vessels, chemical equipment, boilers, oil storage tanks, etc. In industries of petroleum, shipbuilding, and machine manufacturing.

TM-8812, TM-8811, Can measure any hard materials, including steel, cast iron, aluminum, red copper, brass, zinc, quartz glass, polyethylene PVC, Gary cast iron, nodular cast iron and other materials.

TM-8810,Can measure only 11 types of materials, including steel, cast-iron, aluminum, red copper, brass, zinc, quartz glass, polyethylene, PVC, gray cast iron, nodular cast iron。

Ultrasonic Thickness Gauge TM－8811：

 Used the exclusive Micro-computer LSI circuit and crystal time base to offer high accuracy measurement & fast measuring time. 

   * Wide measuring range and high resolution.

     * Digital  display  gives  exact reading with  no guessing or errors.

   * With  high   power of emission  and  broad  band of  receiving  sensitivity, the gauge can match  probes of different frequencies. That makes it easy to measure the rough surface, even cast iron. It is widely used in almost all kinds of industries.

   * Applicable  to   measure  the   thickness of many materials, e. g. Steel,  Cast iron, Aluminum, Red copper, Brass, Zinc, Quartz glass, Polyethylene, PVC, Gray cast iron, Nodular cast iron.

    * Automatic power off to conserve power.
