METTLER TOLEDO US and Canada

Conductivity Standard Solutions

Provided for sensor verification and recalibration, conductivity standards are pro-

duced, analyzed and documented in the METTLER TOLEDO Thornton ISO9001

certified facility with processes similar to those used to calibrate high accuracy

Thornton conductivity sensors. They are provided with label and certificate with

lot number, certified value, expiration date, plus ASTM and NIST traceability data.

These standards are analyzed and used at equilibrium with the atmosphere.

Thornton conductivity

systems are routinely used

by other instrument suppliers as the

reference to provide traceability when

calibrating their instrumentation.

Calibration of Conductivity Sensors

Thornton Auto-loop Factory Calibration System

Thornton conductivity sensors are industry standards for determining water purity

and solution concentration. Thornton ISO 9001 factory calibration and certification

are NIST and ASTM traceable using Thornton’s unique ultrapure auto-loop calibra-

tion system. Certification includes test and accuracy, plus materials as noted in

sensor specifications.

USP pharmaceutical water monitoring requirements are met with sanitary sensors

which provide accurate conductivity and temperature measurement. 316L stainless

steel Tri-Clamp mounting sensors have an electropolished finish with roughness

average (R

) < 0.2 µm, < 8 µin.

4-electrode sensors are ideal for monitoring high conductivity applications,

clean-in-place (CIP) solutions and deionizer regenerant concentrations.
