Shipping was fast and ordering was easy!

Timely service and reliable equipment/standards

Good product, shipping, and package. Instructions are detailed,but kinda hard to understand at 1st.

I bought a combo meter for our soil microbe testing lab it’s easy to calibrate and at the moment it works fine my one complaint is for the money I spent it really should come with more calibration solutions and cleaning solutions but so far ( 1 week ) it’s functioning properly. It did arrive quickly but I also paid a little to get it quickly as our old meter crapped out. Comes in a nice padded case.

Shipping was as expected.
