Thomas One-Shot Traceable Conductivity Standards
Traceable to NIST standards
- Accuracy: ±0.25%
- 100% compatible with all makes of equipment
- For use in the lab and the field
Single-use standards eliminate concerns about external container contamination. Each container is labeled for calibrating conductivity (micromhos), resistivity (megohms) and dissolved solids (parts per million) of KCl. Vials have an extra-large opening and depth (1 3/4" dia. x 3 1/2" D) which allows calibration to be done in the vial.
Standards come with step-by-step calibration instructions, traceability information and a certificate of analysis. Sold in packs of six vials and each vial contains 100 mL of standard. Thomas number 3239M80 contains one vial of each standard with the exception of Thomas number 1235D12.
