inoLab® Laboratory Multi-parameter Instruments

inoLab® pH/Cond 720 and inoLab® Multi 720

 

  • Compact
  • Versatile
  • Easy-to-use
 

The inoLab® pH/Cond 720 is a meter for initial processing of routine pH/conductivity measurements. The inoLab® Multi 720 allows the measurement of pH and ORP, dissolved oxygen, conductivity and salinity as well as temperature. The instruments are suitable for standard measurements where GLP-documentation is not required.

Additional features:

  • Easy-to-clean, touch-sensitive keypad
  • Simplified operator convenience
  • Bench and wall-mounted models
  • Can also be operated on battery power
  • Country-specific units
  • Application-oriented displays

inoLab® pH/Cond 740 and inoLab® Multi 740

 

  • Multi-functional
  • Precise
  • Communicative
 

As high-end instruments, the inoLab® pH/Cond 740 and the inoLab® Multi 740 have a resolution of 0.001 pH units. They also have all the functions necessary for making ion selective measurements. With the inoLab® Multi 740 dissolved oxygen is measured as %, mg/l or mbar. The pH/Cond 740 and the inoLab® Multi 740 can be used to measure the salinity and TDS (Total Dissolved Solids) as well as conductivity and specific resistance.

The optional built-in printer as well as the graphic display with operator guidance increase the measuring convenience and allow QA-compliant documentation.

Additional features:

  • 5-point calibration by linear regression
  • Freely selectable buffer sets
  • Graphic evaluation possible
  • Built-in digital plotter
  • Connection for bar-code reader or PC keyboard
  • User selectable languages
  • Limit input with acoustic alarm
  • Multi-level GLP functions including password-protected operator levels
  • Free-of-charge downloads for MultiLab® pilot or terminal

inoLab® pH/ION/Cond 750 – The ultimate measurement technology by WTW:

 

  • Two galvanically isolated pH inputs
  • Multiple conductivity functions
  • Menu-driven with backlit graphic display
 

This ultimate multi-parameter meter with its two galvanically isolated pH inputs allows independent and simultaneous measurements of pH, ORP or ion concentrations. Calibrations with up to 7 standard solutions can be performed to achieve precise measurements across the entire characteristic curve of an ISE electrode. The wide range of calibration procedures allows for even the non-linear portion of the calibration curve to be accurately defined.

In addition to direct potentiometric methods, the following advanced methods are also included:

  • Known addition/known subtraction
  • Sample addition/sample subtraction
  • Double known addition
  • Blank value correction
  • Known addition with blank value correction
  • Reference measurement

In addition to pH and ISE capability, and with features such as the ability to measure salinity, TDS, specific conductance, resistance and temperature coefficients, this versatile meter can perform all required conductivity measurements. Temperature coefficients are pre-programmed for NaOH, HCl, KCl, and NaCl. Plus, individual (non-) linear coefficients can be entered into the instrument. Additional features include the measurement of

sample concentrations by conductivity and two dimensional temperature concentration field to determine accurate reference conductivities. Comprehensive additional functions such as measurement data management, PC-connection via MultiLab® pilot, GLP-compliant calibration and measurement data acquisition and a bidirectional RS 232 interface permit seamless integration into contemporary laboratory routines.
