pH Meters - 200 Series Meters

Complete GLP/GMP/ISO documentation.

All calibration points are time and date stamped. Results are recorded along with time, date, units, temperature, channel, and a stability indication. Add alphanumeric sample identification and a sample number with ease. All results are sent to a printer or computer and can easily be recalled.

Data logging and RS232 output.

Press the Print key to send the current reading of all active channels to computer or printer. Use data logging to select a time interval for measurements to be taken and recorded. The internal data log stores up to 620 results and all points are automatically sent to the RS232 port. The bi-directional interface of this instrument also allows complete control of the meter via computer. Command strings can be sent by a computer for inline processes.

Standardization is easy.

Just press the Standardization key and follow the standardization menu. 200 Series Meters provide easy-to-follow instructions for good lab practice. The meter will accept the buffer reading when stable and auto compensate for temperature. The meter also performs electrode diagnostics.

Calibration data is available for each standardization.

Simply press the Cal Data button for a complete listing of calibration points, time and date of standardization along with electrode efficiencies. Press the graph soft key to see a graph of the calibration curve.

User-friendly.

The large, backlit display shows time, date, and all active channel measurements and units. Display multiple channels simultaneously. Plain language menus step you through each procedure and "soft keys" allow quick access to the most frequently used features. The help key is always ready with easy to understand descriptions of current options. Error messages clearly explain any problems, helping to ensure accurate measurements.

Great choice for multiple users.

Four features help with uniformity in the use of the meter. Activate the standardization delay and the unit will not complete the standardization process until the programmed time has lapsed. Set the calibration reminder to ensure routine standardization. Use the strict calibration setting to prevent measurements when a calibration is due. Use data alarm to let the meter tell you when data is outside of your range.

pH; Exceptional pH measurement.

Adjustable resolution to 1, 2 or 3 decimal places. Accuracy of 0.001 pH units. Standardize up to 5 calibration points. Choose from 26 preprogrammed buffers, create a custom set of up to 5 buffers or manually enter buffers. An error message will let you know if your electrode is out of specification. Point-to-point calibration and automatic temperature correction makes standardization very reliable.

mV; mV readings.

Adjustable resolution of 1 or 0.1 mV. Perfect for oxidation-reduction potential (ORP) measurements. Create a relative mV offset for titrations and an array of other applications. Excellent for troubleshooting pH or ion selective electrode problems.

Temperature; Automatic or manual temperature compensation.

Internally programmed temperature tables provide automatic temperature compensation when using Denver electrodes with integrated ATC or separate ATC probes. This means you have the most reliable calibration. Without an ATC probe or to use manual temperature, enter the sample temperature. Temperature can be displayed in °C, °F or K.

ISE; Great ion-selective measurement.

Display units in %, ppt, ppm, ppb, mg/l, µg/l, M or a custom ion unit. Choose from fixed or floating point notation. Select from 14 different preprogrammed standard ions, or enter a custom ion name. Improve accuracy by entering up to seven standards for a point-to-point standardization curve. Advanced ion measurement techniques are simplified. Easily perform known addition/subtraction or analyte addition/subtraction analyses. The meter will prompt you through the steps of the addition and ask you for information it needs, then calculate and display the result.

Conductivity; Make conductivity measurements.

Choose from readings in conductivity, resistivity, salinity or TDS. Select display units to float throughout range or fixed µs/cm, mS/cm, ohms/cm, Kohms/cm or Mohms/cm. Standardize up to 5 points for reliable calibration. Temperature correction can be set with a temperature coefficient from 0 to 4.0% per °C or no temperature correction (for USP 23 compliant measurements). Directly measure ppt NaCl salinity, ppt practical salinity, or total dissolved solids (TDS). Set a solids factor for your TDS measurements or let the meter calculate your solids factor. The four-band conductivity circuit makes this one of the most accurate conductivity meters available.

Modes for each model

• 215 pH/mV/temp
• 220 pH/mV/temp/conductivity
• 225 pH/mV/temp/ISE
• 250 pH/mV/temp/conductivity/ISE
