 The Panametrics- NDT™ 25MX PLUS is an ultrasonic precision thickness gage that provides cost-effective solutions in applications where the opposite side of the test material is difficult or impossible to reach. Multipoint and single thickness measurements can be made on a wide variety of materials including metal, plastic, rubber, glass, fiberglass, and composites.

MX-8 Multiplexer
|
|
Number of Channels: 1 to 8, user selectable
Channel Switching Rate: 1, 2, 4, 8, 16, or 20 Hz, user selectable
Size: 3.2" x 5.9" x 1.25"(149.9 mm x 81.3 mm x 31.8 mm)

Multipoint Thickness Measurements
Connected to the optional MX-8 multiplexer, the 25MX PLUS has the ability to collect and display thickness measurements from up to 8 separate transducers.
Special software on the 25MX PLUS
allows the user to select:
• Number of channels (1-8)
• Mux Mode
- Off
- Single Channel (manual switching)
- Single Sequence (switch through selected channels on command)
- Sequence (continuous channel switching)
• Channel Rate (1, 2, 4, 8, 16 or 20 Hz; thickness output and channel number)
Single Thickness Measurements
The 25MX PLUS operates as a 'standard' precision thickness gage when not connected to the MX-8 Multiplexer.
