CalBox for organizing calibration solutions

The unique CalBox from Apera Instruments helps to organize all solutions in one place and eliminate clutter during the calibration process. It can hold up to 4 different solutions at the same time and has a hole in the center for inserting or holding an electrode. Each of the 4 solutions can be closed with a lid after calibration so that the solutions can be used several times. The CalBox is an ideal accessory for pH and EC measuring devices, but also for any other measuring device that needs to be calibrated regularly.

Stickers for frequently used pH and conductivity calibration solutions are included.
