Scale Calibration & Repair in Pasadena & Baytown, TX

Scale calibration and repair along the Houston Ship Channel. Petrochemical plants, plant labs and logistics yards from Pasadena to Baytown keep our TDA-licensed technicians busy with floor and drum scales, intrinsically safe bench scales and QC balances. We calibrate on your site and document every scale. Our technicians haul in their own certified test weights for floor, drum and crane scales, so your unit doesn’t have to supply any.

Refining and Chemical Country

  • The Bayport Industrial District in Pasadena holds more than 60 chemical plants, with neighbors along SH 225 and the Ship Channel.
  • Refineries and chemical complexes in Baytown cover thousands of acres with refining, olefins and polymer units.
  • Petrochemical plants along the Ship Channel make plastics, polyurethane and specialty chemical materials.
  • What they weigh: additive and catalyst charges on floor and drum scales, samples in plant labs on analytical balances, and outbound packages on bench scales.

What should we tell you about site access?

Tell us your site requirements when you book, and send your scale list at the same time so we bring the right weights.

Do you sell intrinsically safe scales?

Yes. We carry intrinsically safe bench scales and portable balances from A&D for hazardous-location work. Check the area rating with your safety team and we will match the model.

Can plant lab balances get NIST-traceable certificates?

Yes. NIST calibration with a NIST-traceable certificate starts at $395 for balances up to 2.2 kg, and in-house calibration starts at $95.
