The ESSENTIALS pH Meter is truly an essential piece of equipment. It is water and drop resistant but must not be fully submerged. If accidentally dropped into water it will float so you can quickly take it out to avoid damaging the electronics.

For best results, we recommend calibrating this regularly to ensure a lifespan of 1 to 3 years depending on the sampling rate. The energy-saving feature will turn off the pH meter when not in use to save battery life.

• Easy to use
• Long life expectancy
• Accurately shows pH level 

How to Use

Simply turn on and place the sensor inside your solution. When it beeps, the measurement can be read.

You will need to calibrate your Essentials pH Pen Meter using a Buffer 7 bottle (the meter includes a small pouch). Simply dip your meter in buffer 7, and then hold down the calibration button until the display says CAL. The Essentials pH Meter will then calibrate the device.
