pH Meter Calibration Solution Kit(4.00,7.00&10.01) with pH Electrode Storage Solution Kit,3 Bottles pH Calibration Buffer Solution and 2 bottels KCL pH Probe Solution for pH Meters

Nice

I purchased this package of 50ml x 3 PH calibration "Ready-Made" solutions @ 4.0, 7.0 & 10.04 and 2 x 10ml KCL PH probe Storage solutions that should last years as only a few drops are needed for the "glass tip sponge" to stay hydrated. The calibration solutions are sealed and can be stored at room temperature until they are opened and used for the first time - then refrigeration is recommended so they stay "fresh and accurate". The storage solutions are a MUST for any PH/ORP and other meters that have a tip that cannot dry out. This will extend the life of the probe for maximum amount of life of probe (no pre-mature failures under normal operating conditions and care in cleaning of delicate glass tip).I bought this as part of a package offered by Amazon containing the same brand Professional PH Meter, the optional Extra Probe (total 2 probes, 1 meter), the meter came with 6 packets (2 of each type) calibration crystals for 4, 7, and 10.04 calibration solutions when mixed with 220 ml of distilled water for each. This calibration/storage solution kit was offered at a discount with the Meter w/extra probe so I decided to get this kit. It is an excellent product even if you already have a PH meter because the solutions are of excellent quality and at 50ml each x 3 (calibration) and 2 x 10ml KCL probe tip storage solution - you are getting more than enough - also comes with a temperature vs PH measurement chart which shows you how at extreme temperatures, high or low, how your PH meter measurement may need to be adjusted manually to get a true measurement as temperature does affect the way a PH meter measures PH. It also contains a chart containing PH measurements for many raw foods from fruits, berries, vegetables, to meats, dairy, juices etc... both are laminated cardstock for water/stain resistance, and are very handy when using to can, preserve various foods as a supplement to taking PH measurements.Supports PH meters with 2 or 3-point calibration - and verifies operation/accuracy of either type at high acidity, high alkalinity and neutral.Chris

Perfect for calibrating and storing your PH meter.

Good quality solution. I compared reading on solution to OEM and was comparable.Seems to be doing its job.

Muy buenos

Kit worked excellent to calibrate my Vivosun Digital pH Meter

The media could not be loaded. No instructions????

I use this solution regularly and its very consistent and easy to use. The storage solution is a bonus. I use it on my pens that both require it and don't require it. It makes them last way longer
