### ⭐⭐⭐ Work emergency
*by L***S on 8 April 2023*

I brought these to test the FE of a waste water treatment plant.I needed them quickly as our usual suppliers were out of stock of the ones we use normally.These are a little difficult to work with but the product itself is OK a little cheap feeling but saved our bacon for a few days.
