Description

The MA917B/1 is a lab grade refillable glass electrode designed for fast response and an extended life.

Design Features

The MA917B/1 probe makes pH testing easy and fast.

Top features include:

Double Junction

The double junction design reduces risk of clogging with the reference cell physically separated from the intermediate electrolyte.

Refillable

The MA917B/1 refillable with MA9011 3.5M KCl. This solution is sliver free. Sliver can cause silver precipitate to form at the junction resulting in clogging. Clogging causes erratic and slow readings. The ability to refill the electrolyte also extends the life of the electrode. 

Glass body

The glass body is easily cleaned and resistant to chemicals.

Round tip

The round design of the tip provides the largest possible surface area for faster readings and is well suited to testing liquid samples.

Care and Use

Properly maintaining your pH probe will give you fast, accurate results for longer.

Here are our top four tips.

1. Always store with the cap full of buffer or storage solution not water.

2. Clean your probe regularly by soaking in cleaning solution.

3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH probe sensor.

4. Gently stir the probe in the sample for a faster result.
