Waterproof housing enables working in difficult conditions. Minimised size and weight facilitate field work. The most important features of PH-130 are: - high accuracy and stability; - automatic and manual temperature compensation; - automatic recognition of pH buffers;... -
Page 7: The Outside View
- 3 - THE OUTSIDE VIEW On the front wall of the meter there is a graphic LCD placed (Pic. 1), which displays the following readings: - pH measurement or mV measurement in mV units; - temperature measurement. At the top of the LCD the current time and date are displayed. Choosing particular functions is described in the chapter 17.1. - Page 8 In the upper wall of the meter connectors are placed with the symbols given below: BNC-50 input for connecting the combination pH or redox electrode; Chinch (RCA) input to connect the temperature probe; input for connecting the power adapter.

Page 15: Preparation Of The Ph Electrode
- 11 - PREPARATION OF THE pH ELECTRODE The electrode should be prepared to work according to the manufacturer’s instructions. It is crucial to keep the electrode’s membrane clean, wash it accurately with distilled water after each measurement and gently dry with tissue paper. -
Page 16: Calibration
In case of measurements in acids calibration in 2 buffer solutions: 4.00 and 7.00 pH is recommended, in case of alkali measurements calibration in 7.00 and 10.00 pH buffers is advisable. In PH-130 the electrode characteristic is approximated linearly between the calibration points. Entering... -
Page 17: Calibration In Buffer Solutions
- 13 - 10.1. Calibration in buffer solutions When the electrode is prepared for the measurement, start the calibration in the buffer solutions. The buffers may be applied randomly. To start calibration: - connect the pH electrode and temperature probe to the F and t connector respectively (Pic. -

In order to enter the temperature value, press the window and in the open screen press the window, the numerical keyboard will MANUAL TEMP. appear to enter the value and confirm with the button. VWR Collection PH-130 pH-meter instruction manual v1.0x... -
Page 19: Checking The Electrode Condition
- 15 - CHECKING THE ELECTRODE CONDITION After pH electrode calibration the meter calculates its parameters: offset in pH units and slope defined as efficiency in percents. The electrode offset may be defined in pH or mV units. An ideal electrode immersed in the 7.00 pH buffer before calibration should indicate 7.00 pH which equals 0.00 mV. -
Page 20: Ph Measurement
Accurate laboratory measurements require using of a magnetic stirrer. NOTE: exceeding the measurement range is signalised with red colour of the displayed pH value; exceeding the temperature compensation range – with yellow colour. VWR Collection PH-130 pH-meter instruction manual v1.0x... -
Page 21: Measurement With Manual Temperature Compensation
