A rugged & stylish design, digital back lit display, push button navigation, fully waterproof and an affordable price to rival its less quality conscious competitors.

Hydroponic growers who are looking for a meter to read the pH of a solution no longer need to purchase cheap throw away pH meters or have to deal with the task of colour matching litmus paper or pH indicator solutions – the Bluelab pH Pen delivers on affordability as well as quality.

Simply turn the meter on, dip the tip of the meter in the solution you are measuring, allow the pH reading on the LCD screen to stabilise, and then withdraw it to take your final reading.

The pH Pen also doubles as a temperature meter and provides readings in degrees Celsius (°C) or Fahrenheit (°F) .
