pH - mV - ion - conductivity - resistivity - salinity - TDS - dissolved oxygen - temperature

pH

• Multi-point (1...5) calibration for more linearity
• Selectable resolution frm 0.001 pH to 0.1 pH
• Automatic calibration with any of eleven pre-prorammed and five user specified pH buffers. Create your own buffer/temperature tables!
• Accepts pH electrodes with any zero point (Eo) between ±999 mV

mV

• Features mV calibration for accurate ORP measurements
• Selectable resolution from 0.1 mV to 1 mV

Ion

• Direct concentration measurement.
• Multi-point (2...5) calibration and an additional blank correction for measuring low concentrations.

Conductivity

• Multi-point (1...3) calibration for more linearity.
• An electrode with a typical cell constant of 1 cm^-1 (standard) permits to measure from 0.01 µS/cm to 200 mS/cm in five ranges.
• An electrode with a typical cell constant of 0.1 cm^-1  permits to measure from 0.001µS/cm to 20 mS/cm in five ranges.
• An electrode with a typical cell constant of 10 cm^-1  permits to measure from 0.1µS/cm to 2000 mS/cm in five ranges.
• Automaticly selects correct range and frequency.
• Selectable reference temperature: 20°C or 25°C     
• Automatic calibration with any of three preprogrammed and three user specified standard solutions.Create your own buffer/temperature tables!
• Allows to lock the initial conductivity range to avoid non-linear titration curves.
• Accurate low conductivity measurements by eliminating the capacitve component of the electrode and its cable (avoid the use of long cables!).

Dissolved oxygen

• Operates with a galvanic dissolved oxygen electrode requiring no polarisation time and no zero calibration.
• Selectable resolution from 0.01 mg/l (0.1%) to 0.1 mg/l (1%)
• Automatic air pressure compensation 600-1300 hPa.

Temperature

• Reads temperatures with 0.1 °C resolution.
• Manuel or automatic temperature compensation (O₂: 0...50°C).
• Calibrates temperature probe for quality measurements.

Inputs

• Two inputs for pH, mV, Ion, dissolved oxygen or conductivity + corresponding temperature and reference inputs.
• Low voltage DC input for e.g. a mains adaptor.

Outputs - two versions available:

• C3030: with USB communication port and RS232 interface.
• C3031: with Ethernet communication port and RS232 interface.

Data-logging

• Up to 12000 data sets can be stored manually or at a programmable interval.
• Allows to mix data  from all ranges in the same table.
• Freely downloadable data acquisition software enables to view, store and edit the measurements in your computer.

Cabinet

• Robust dust and splash-proof cabinet.
• An optional wall mounting kit allows to fix the meter to any wall making more space available on the desk.

Display

• A large bright LCD screen with white backlight enables to view all channels individually or simultaneously.
• Stability indicator prompts the user when readings should be taken.
• Hold function allows to freeze the display for convenient reading or recording.
• The interactive LCD screen provides step by step instructions in the language of your choice (English, Dutch, French, German)
• Real-time clock displays time and date.
• Shows a GLP report on the LCD screen.

Special features

• Two-way communication with a computer using USB, Ethernet or RS232.
• Can be programmed to continue automatically with the measurements or data-logging after a power failure.
• Password protection prevents any unauthorised modificaton of the instruments' settngs.
• No electrical interference between pH/ORP/Ion and conductivity eletrodes in the same solution.
• Optional 12 V adaptor.
• Three year warranty.

GLP

• All procedures for a "Good Laboratory Practice" are on board.
