Edison-1M – Ultrasonic Thickness Gauge

The Edison-1M is the memory-enabled general purpose model in Modsonic’s Edison series. It includes all the features and specifications of the Edison-1 — measuring range, accuracy, one-step calibration, sealed keypad, and dual crystal probe — with two key additions: an onboard memory of 2000 thickness readings with 4-digit IDs, and an RS-232 port for direct PC and printer connectivity.

The Edison-1M stores up to 2000 thickness readings onboard, each tagged with a 4-digit ID for location or point identification. This makes it suitable for systematic inspection surveys such as corrosion mapping on tanks, pipelines, and vessel walls where each reading point needs to be tracked and recorded.

The Edison-1M is equipped with an RS-232 serial port that allows stored thickness readings to be uploaded directly into a PC spreadsheet or printed via a compatible printer. This eliminates manual transcription of field data and speeds up reporting for corrosion monitoring and quality control surveys.

The Edison-1M shares the same measurement specs as the Edison-1: a measuring range of 1 mm to 300 mm (subject to material, transducer, surface, and temperature), 0.1 mm resolution, accuracy of 0.1 mm up to 60 mm and 0.5% above 60 mm with the standard probe DT 201, and built-in V-path correction for improved accuracy.

Yes. The Edison-1M allows selection between Imperial (inches) and Metric (mm) measurement units, making it suitable for both domestic and international inspection work and for clients whose standards require inch-based reporting.

The Edison-1M uses a Dual Crystal (Transmitter-Receiver) type probe with a detachable probe cable. A full range of probes is available for all applications. Calibration is a simple one-step process for steel, with velocity adjustable from 1000 m/s to 9999 m/s for other materials.

The Edison-1M operates on two standard AA size Penlite dry cells (alkaline or NiCd) and delivers 18 to 20 hours of operating time with alkaline batteries. It weighs 225 grams with batteries and measures 125×65×30 mm, keeping it compact and easy to carry for field inspection work.
