About Us

  Our lead technician has over 55 years of Smiths experience and our staff has a combined total of over 120 years of experience in the servicing of Smiths & British Jaeger Instruments.



During the early morning hours of Sept. 2nd our facility was buried under 6 ft. of water as Hurricane Ida passed through the New York area.

A good portion of our repair parts inventory along with numerous pieces of equipment were destroyed and our building requires substantial repairs, thus we are not able to accept any Instruments/Gauges for repair or restoration at the moment.

UPS, USPS and FedEx have all been instructed to return any packages addressed to us to the Sender as we do not currently have the ability to securely/safely store them.

Please note that our Sales Dept. is NOT affected and will continue to accept process and ship orders for new Smiths Instruments/Gauges, Parts & Accessories. For information, or to place an order for any of these items, please phone us weekdays between 8am & 4:30pm (Eastern Time) @ (914) 381-3600, or e-mail us 24/7 @
