This water quality calibration solution set is ssential for accurate water quality measurement.
This calibration-set-provides the 5 key solutions required to calibrate the pH and conductivity functions of the PST-5N1 water quality tester.

The pack includes 50mL bottles of the commonly used pH 4.01,  pH 6.86 and pH 9.18 buffer solutions along with a 50mL bottle of 1413 µS/cm conductivity and 35 PPT salinity calibration solution, allowing users to perform routine calibration quickly and confidently.

Ideal for hydroponics, aquaculture, environmental monitoring and general water quality testing.

Contents of the Water Quality Calibration Solution Set

• pH 4.01 Buffer Solution 50mL
• pH 6.86 Buffer Solution 50mL
• pH 9.18 Buffer Sollution 50ml
• 1413 µS/cm conductivity calibration solution 50mL
• 35PPT salinity solution 50ml
• 5 labelled calibration solution cups of 30ml capacity

(Solutions supplied ready to use. No dilution required.)

Remember pH probes last much loger and respond more accurately and quickly if you store them with the glass bulb wetted with KCl. Order KCl as well if you are not sure if your probe is being stored correctly.

Compatibility

• This water quality calibration kit is designed for use with  for other compatible pH and conductivity meters

Usage Notes

• Use 12ml of fresh solution for each calibration. Make sure the glass bulb is covered
• Do not return used solution to the bottle
• Store tightly sealed when not in use
