The SevenCompact and SevenGo Duo meters incorporate Intelligent Sensor Management (ISM). This ingenious func-tionality offers great advantages such as:

After connection of ISM sensor immedi-ate transfer of current sensor calibration data and Sensor ID to meter.

After calibration of ISM sensor immedi-ate transfer of calibration data from meter to sensor chip.

When an ISM sensor is connected, the initial calibration data in the sensor can be reviewed and transferred to a PC or printer.

The last 5 calibration data stored in ISM sensor including current calibration can be reviewed and transferred to a PC or printer.

The maximum temperature that the ISM sensor has been exposed to during measurement is monitored automatically and can be reviewed for valuation of electrode lifetime.

INGOLD has been producing electrodes since 1948, a name that has been syno-nymous with the success of combined pH electrodes ever since. In 1986 INGOLD joined the METTLER TOLEDO group. The result is the development of the InLab range of laboratory electrodes. InLab is thus the product of over 60 years of expe-rience in the manufacture of electrochemi-cal sensors. And so the tradition continues with every METTLER TOLEDO sensor: INGOLD inside

InLab GlossaryDesignation Description

Type of membrane glass

A41 glassParticularly resistant to chemicals; suitable for high temperatures up to 130 C; ideal for biological media.

HA glassHigh alkali glass for use at high pH values and high temperatures; extremely low alkali errors; extremely robust membrane.

HF glassEspecially suitable for media containing hydrofluoric acid; up to a HF concentration of 1 g/L.

LoT glassLow resistance glass for use at low temperatures (LoT = low temperature); also suitable for low ion concentrations (ultra-pure water); the glass of choice for thick membranes (puncture or surface electrodes).

U glassUniversal glass, tried & tested in standard applications; especially suitable for small membranes (microelectrodes).

Type of junction

Click & ClearThanks to the press mechanism, the sleeve junction is easy to open with combined perfectION ISE; quick cleaning and stable measurement values are ensured even in difficult samples.

Movable glass or PTFE sleeve

Movable sleeve junctions that can be easily and thoroughly cleaned.

Immovable glass sleeve

Fixed sleeve junctions for large contact area between reference electrolyte and measurement solution.

CeramicConventional ceramic junctions for liquid electrolytes or in combination with SteadyForce.

Ceramic ring Large ring-shaped ceramic junctions for flat membranes.

Open junctionOpen connections without junctions together with XEROLYT polymer electrolyte.

Porous PTFE Large contact surface polytetrafluoroethylene (PTFE) junctions.

Technologies, reference systems and reference electrolytes

ARGENTHAL

AgCl granulate-filled cartridge, which supplies the silver ions for the chemical reaction on the conducting wire. The silver ion trap stops the Ag+ ions from discharging into the electrolyte solution,thus preventing contamination of the junction when using sulfides and proteins.

DPA-Gel Gel electrolyte for electrodes with SteadyForce.driTEK Reference system for ISFET electrodes.

EquithalSymmetrically structured conducting elements guarantee minimum response times and highly stable potentials when fluctuating temperatures are involved.

FRISCOLYTSpecial electrolyte for measurements at low temperatures and for media with organic components (e.g. oil, proteins, etc.). Recommended for storage of electrodes with XEROLYT.

ISM (Intelligent Sensor Management)

In sensors with ISM, important information, such as calibration data, is stored on a chip directly in the sensor and automatically detected by the meter. Only with SevenCompact and SevenGo Duo meters.

SteadyForceReference system in which the electrolyte is pressurized (3 bar) to ensure discharge of electrolyte even in viscous samples.

XEROLYT Solid polymer electrolyte in combination with open connections.

Shaft materials

Stainless steel 316L (V4A) grade stainless steel.

EpoxyVery strong plastic with excellent chemical and mechanical resistance. For very robust sensors.

PEEKPolyetheretherketone: Highly temperature-resistant plastic with excellent chemical and mechanical resistance. For professional and heavy-duty sensors.

Polysulfone Plastic with good chemical and mechanical resistance.

PPSPolyphenylene sulfide: Partly crystalline, highly temperature-resistant plastic with excellent chemical and mechanical resistance. For robust dissolved oxygen sensors.

With this knowledge, combined with many years of experience in the manufacturing of electrochemical sensors, we can therefore proudly present a product range that continues to produce success. Customers with an extremely wide range of requirements have tested, and are inspired by, our sensors. See for yourself!

Solid foundationThe InLab Routine Pro is a reliable work-horse for any lab. With EQUITHAL tech-nology and the ARGENTHAL reference system including silver ion trap, this sensor fulfills two fundamental requirements for optimum pH measurement. I can rely on fast response behavior and clean junctions. The InLab Science with sleeve junction is used for more complex sample matrices, such as emulsions or biological media.

For more information, see pages 89.

Well-equipped for challenging tasksFor my more technically challenging measurements, I need an electrode such as the InLab Expert. With its highly resistant PEEK shaft and XEROLYT polymer elec-trolyte with open junction, it is built to with-stand even the toughest conditions. When the very highest performance is expected, I opt for the InLab Power with the success-ful SteadyForce reference system.

For more information, see pages 1011.

When form is a factorI expect a pH electrode to be optimally equipped for my specific measurements. Electrodes such as the InLab Solids for penetration measurements, or the InLab Micro for the measurement of small quanti-ties have the correct combination of form, membrane glass, and reference system, and fulfill these expectations perfectly.

For more information, see pages 1217.

5Combined power for ORP/Redox measurementWhen taking redox measurements in different samples, the right combination of precious metal and junction type is all-important. For my diverse applications I therefore opt for the InLab Redox platinum electrode. Thanks to the InLab Redox Pro with glass sleeve junction, blocked junc-tions in complex samples are no longer an issue.

For more information, see pages 2223.

Equipped for mobile use Mix-ups can happen easily when on the move. Im glad that the pH electrode InLabExpert-Pro-ISM-IP67 with Intelligent Sensor Management technology keeps track at the same time. For use in the fac-tory, I require a robust and watertight sen-sor such as the InLab 605 for dissolved oxygen, or the InLab 742 for conductivity.

For more information, see pages 2627.

Sensitive to ionsThanks to the replaceable membrane module on the DX218-NH4

+, I can replace my ammonium half-cell with another half-cell at any time. The perfectION comb F-, with its integrated reference electrode and matching accessories, offers the complete solution for my fluoride measurement.

For more information,see pages 2831.

Conductivity on all levelsSince my measurements in distilled water require absolute precision, I like to rely on the stainless steel InLab 741, in which the actual cell constant has already been deter-mined for me. For samples with higher con-ductivity, the InLab 731 delivers the required results.

For more information, see pages 2425.
