CalBox Calibration Box

Apera Instruments’ unique CalBox helps users organize all solutions in one place and eliminate clutter during the calibration process.
The CalBox can hold up to 4 different solutions simultaneously. The hole in the center of the CalBox is used to insert the electrode.
This CalBox is a great accessory for pH meters and also for any other meter that needs to be calibrated regularly.
After calibration, the lids are sealed so that the solutions can be used several times.
Stickers for frequently used solutions for pH and conductivity tests are included.
