Great pH pen
1 of 1 found this helpful This is my second blue lab pH pen. The first lasted 4 years then the keypad started acting up. They are very easy to calibrate and use. The accuracy and remaining calibrated are excellent. Best of all it uses 1 AAA battery not the expensive lithium or watch batteries. You will need the probe storage solution along with the pH 4 & 7 calibrating solutions.

Excellent vent fan
The 6" Hyper Fan is an excellent choice for a ventilation fan. It's small, quite and very well made. The included speed control allows you to adjust the volume of air flow to fit your needs. And, it's powerful enough to push or pull air through a filter.

Great carbonator cap
I use this carbonator cap on 1 & 2 liter soda bottles to make carbonated water at home. The cap fits perfectly and is easy to use. Haven't had any problems with leaking. The stainless steel cap is much better made than the plastic ones and should last a long time.
