Edgetech Instruments Assists Ambri

Edgetech Instruments provides Ambri, a manufacturer of innovative liquid metal batteries located in Marlborough MA, with the PPM1 Trace Moisture Analyzer from their facility in neighboring Hudson, MA. The PPM1 sensor utilizes a proprietary P205 (phosphorous pentoxide) technology to provide accurate, long term trace moisture measurement at low Parts Per Million by Volume (PPMv) moisture levels. The PPM1 is used to monitor various inert blanketing gases during the manufacturing of Ambri’s liquid metal batteries, as even small amounts of moisture can have an adverse effect on the results and performance.

The PPM1 sensor utilizes a proprietary P205 technology to provide accurate, long term trace moisture measurement at low PPMv moisture levels.

Ambri Inc. is developing an electricity storage solution changing the way electric grids are operated worldwide. Ambri will enable the more widespread use of renewable generation like wind and solar, reduce power prices and increase system reliability. Ambri’s technology, the liquid metal battery, was invented in the lab of Dr. Donald Sadoway, a professor at the Massachusetts Institute of Technology. At MIT, the Liquid Metal Battery Project built upon Professor Sadoway’s 40 years of experience working with extreme electrochemical processes, ranging from aluminum smelting, to molten oxide electrolysis for extracting oxygen from lunar regolith, to lithium polymer batteries.

Ambri’s Manufacturing and Process Engineering Senior Manager, Brian Liebl, states, “Edgetech Instruments’ local support, along with their economical and reliable product offering have helped us achieve a higher level of quality in our manufacturing processes.”
