CONDUCTIVITY-TEMPERATURE TRANSFER STANDARD Idronuat

CONDUCTIVITY-TEMPERATURE TRANSFER STANDARD CT 01

The "Conductivity-Temperature Transfer Standard" is a compact and rugged instrument designed For the metrology laboratories to perform calibration of oceanographic CTDs probes.

It combines a:

Primary Standard 100 ohm SPRT (Standard Platinum Resistance Thermometer), a large size Idronaut self flushing cell provided with seven internal rings of fused platinum in the quartz with a microprocessor controlled high resolution and high accuracy electronic amplifier.

Optionally, the "Conductivity-Temperature Transfer Standard" can become a redundant measuring system when equipped with an additional temperature and conductivity sensor.

The high performance electronics collects and transmits the temperature and conductivity readings through the RS232C interface from 1 to 10 times per second. The functions of the "Conductivity-Temperature Transfer Standard" are managed by means of a simple communication protocol with the RS232C interface.

Features

Large size self flushing cell provided with seven internal rings of fused platinum in the quartz, specifically developed to make the re-calibration and checking easier by using a single ampoule of standard seawater.

High performance 24-bit digitizing circuits.

Temperature controlled oven conditions the electronics to obtain drift free measurements.

0.1ppm Vishay resistors used as a reference for the CT electronic preamplifiers.

Redundant CT standard reference sensor pair.

Windows 98/2000 software simplifies system operations and automates the CTDs calibration.
