CONDUCTIVITY CALIBRATION WITH AN INSACAL MASTER METER
Flexible caibration tool
With an INSACAL master meter you get a very flexible calibration tool. You can calibrate by closed loop procedures or in an open beaker. This allows you to choose whether your cell is calibrated on-site, in-situ or not. For Pharmaceutical and Medical purposes the quality of water, as an excipient has been defined by the European Pharmacoepia (EP) as well as the United States Pharmacoepia (USP). In order to ship/sell your product in Europe or the United States of America, you must be able to prove that these requirements are met. |
For Purified Water and Water for Injection (WFI) the USP defines the following requirements:
• Meter reports uncompensated Conductivity or uncompensated Resistivity. • The display resolution is 0.1 μS/cm or better. • The meter reads accurately to ±0.1 μS/cm when a 0.1% precision resistor replaces the sensor (to calibrate/verify the meter). • The sensor cell constant is calibrated/verified to ±2% • Temperature accurate to 2°C (effective USP 28) Yokogawa have years of experience in the development of highly accurate conductivity instrumentation for your on-line measurements. Irish Power and Process and Insatech have jointly developed the Insacal Conductivity Calibrator in order to help you achieve these difficult requirements. This is the first master Conductivity standard, accredited to 0.4% or better, in order to allow you meet your WFI quality requirements of 2% cell constant verification with a 4:1 TAR.

FUNDAMENTALS OF GAS FLOW CALIBRATION
Gas flow calibration
Understanding the fundamentals of gas flow calibration is essential for evaluating calibration systems, estimating the magnitude of error sources, developing calibration methods and resolving measurement problems. This application note develops the ideal gas laws into tools that can be applied to real gases in a flow calibration system. In addition it discusses the two ways that flow can be measured and explains why one is preferred over the other. It also covers flow standards and provides guidelines for making reliable measurements. |

ISC450 CONDUCTIVITY TRANSMITTER

How to use a conductivity transmitter
as a concentration transmitter There are two choices for programming the ISC450 for Percent Concentration measurement. The simplest, is to select one of the “built-in” tables already provided in the ISC40. However, if none of these Tables meet the application requirements, then the second option of creating your own Table specific to your needs can be used. This Application Note is designed to guide you through the programming steps required for both options.

Medical Testing Technology at its finest
SECULIFE function testers have been specially developed for testing those medical devices which are used most commonly in clinics – directly at the patient. Great importance is placed upon efficiency and reliability when performing measurements on these devices. The great variety of manufacturers and models of monitoring and therapeutic devices also necessitates high levels of compatibility.
