Remove the Battery Compartment Door

Hold the sensor bottom-side up. 
Use a coin in the slot to turn the 
Battery Compartment Door 
counterclockwise (left-to-right) 
until the indicator on the door is 
aligned with the second mark on 
the sensor. 

Turn the sensor bottom-side 
down so that the Battery 
Compartment Door can drop into 
the palm of your hand. Make sure 
that the battery door gasket stays on the door. The gasket 
is an “O-ring” that is held in place by the tabs on the door. 
Please do not touch the inside of the battery compartment.

Remove the used battery from the Battery Compartment 
Door and replace it with a new identical type battery. 

Note 

that the battery is held in place by the small tabs on the 
door

. The side of the battery with the “+” on it should be 

against the door.

Replace the Battery Compartment 
Door

Put the Battery Compartment Door 
with the new battery back onto the 
sensor. Align the indicator on the door 
with the second mark, and use the 
coin in the slot to turn the door 
clockwise (right-to-left) until the 
indicator is aligned with the first mark 
on the sensor.

(See “Battery Disposal Instructions” under Technical 
Support.)

Troubleshooting the Wireless pH Sensor

If the Wireless pH Sensor loses Bluetooth connection 
and will not reconnect, try cycling the ON button. Press 

and briefly 

hold

 the button until the status LEDs blink, 

and then release the button 

If the sensor stops communicating with the computer 
software or tablet application, try restarting the 
software or application. If the problem remains, press 
and hold the ON button for ten seconds and then 
release the button. Turn on the sensor in the usual way.

Turn Bluetooth off and then turn it back on. Retry.

pH Probe Maintenance

pH Probe Storage

For a storage period of a few weeks or less, rinse the end 
of the pH Probe with distilled water and put the storage 
bottle back onto the end of the probe.

NOTE: To make more storage solution, combine equal 
parts of 4 M potassium chloride (KCl) and a pH 4 buffer 
solution, with a few drops of pH buffer preservative.

You may keep the pH Probe in the storage solution 
indefinitely, but for long term storage, store the pH Probe 
dry. After a period of dry storage, the pH Probe must be 
restored to rehydrate the glass membrane (see below).

Restoring the pH Probe

Use the following procedure to improve the performance of 
a slow pH Probe or to rehydrate the glass membrane after 
dry storage.

1.

Clean the pH Probe using one or more of these 
methods.

If the pH Probe is contaminated with proteins, soak the 
probe in a solution of 1% pepsin in 0.1 M hydrochloric 
acid (HCl).

If the pH Probe is contaminated with inorganic 
deposits, rinse the probe with 0.1 M ethylene dintric 
tetra-acidic acid (EDTA) tetrasodium solution. 

If the pH Probe is contaminated with oil or grease, 
wash the probe in a mild detergent or solvent known to 
be effective for oil or grease.

If the pH Probe is not responding quickly, soak the 
probe alternately in 12 M sodium hydroxide (NaOH) 
and 1 M hydrochloric acid (HCl). Leave the probe in 
each solution for one minute. Rinse completely 
between soakings and end with hydrochloric acid.

2.

Soak the pH Probe in 0.1 hydrochloric acid for 30 
minutes.
