pH15-K Portable pH Meter with BNC connector, ATC and pH electrode

ph15-k portable ph meter with bnc-connector and atc

The PH15-K Portable pH meter kit comprises of a calculator sized portable pH meter with BNC connector, ATC (Automatic Temperature Compensation), as well as a neat carrying case, pH electrode and stainless steel temperature sensor. The temperature sensor can be used as an ATC or for separate temperature measurement.  

Each measure is shown on the digital display. 

PH15-K:- Multiparameter Portable Meter For pH, Redox, and Temperature Measurement 

The PH15-K is a multiparameter meter with the ability to measure the pH value, the Redox Value and the temperature all in the same instrument. The ranges of each of the measure are as follows:

pH measuring range: 0.00 to 14.00 pH,

pH Resolution: 0.01pH

Redox measuring range: -1999 to +1999 mV

Redox Resolution: 1mV

Temperature measuring range: -50.0ºC to 150ºC

Temperature Resolution: 0.1ºC

The ATC operates between 0ºC and 100ºC

The PH15-K is accurate to ±0.02pH, ±2mV or 0.5ºC

Test Existing pH Electrodes

The PH15-K is a pH meter with a BNC connector installed at the front of the instrument to allow the supplied pH Electrode to be connected.

Other pH electrodes with a BNC connector can also be connected to the PH15-K pH meter. This can be particularly useful for isolating problems with already installed pH Electrodes. As these pH electrodes can easily be connected to the PH15-K and the value can be measured and corroborated independently giving allowing the user to see if an unexpected reading is a result of a faulty pH instrument or a pH electrode at the end of it's life-span.

The PH15-K Portable pH meter with BNC connector is supplied with the following:

- 9015-3B plastic bodied combination pH electrode with 1 metre of connecting cable and a BNC connector.

- A8000 Stainless Steel Temperature sensor for auto temperature compensation (ATC) and for separate temperature measuring. 

For Redox (ORP) measurements with the PC15-K Portable pH Meter kit we are able to offer a range of platinum combination electrode suitable for use. Please see our Redox Electrode page to see a list of redox electrodes available. 

The PH15-K Portable pH meter with BNC connector has many uses and offers superior accuracy and repeatability over pH indicator solutions and papers.

Some of the uses for the PH15-K include educational field studies, laboratories, environmental monitoring to simply testing the pH of verily any water based solution.

pHTestr 10 Data Sheet


pH Buffer solutions are solutions made to a known pH value which are very stable and resist changes in that pH value when small quantities of either acid or alkali are added during use.
The most commonly used pH electrodes have an Eo of 7 pH which means they produce a zero electrical signal at 7.00 pH and a positive millivolt potential as thepH falls and a negative millivolt potential as the pH increases. The best way to standardize any pH instrument is by using a 7.00 pH buffer to set 7.00 pH the zero output of the electrode and either 4.00 or 9.00pH as the span depending upon whether the pH values you wish to measure are acidic or alkali.
If your pH values can be either acidic or alkali simply calibrate on one buffer say 4.00 pH and carry out a buffer check on the other buffer 9.00 pH.

AWE Direct News:- New Teflon Junction pH Electrodes and Redox Electrodes

We are now able to supply our P8000-10B series high performance combination pH electrodes with a porous teflon liquid junction, and our R8000-10B series of high performance combination redox electrodes with a porous liquid junction.

The new range of P8000 pH Electrodes and R8000 Redox Electrodes are ideal for solutions which are incompatible with ceramic. Some chemical blends involving strong acids or strong alkali solutions can slowly dissolve the ceramic junction. Other substances can block the ceramic junction such as biological effluents which contain fats, oils or greases. 

The P8000-10B porous teflon liquid junction pH electrodes and R8000-10B high performance liquid teflon junction redox electrodes aim to eliminate these concerns.
