Reviews

Greenhouse Portable Field Kit

Was very pleased with the level of service I received choosing the right equipment for my mobile greenhouse field kit. Pricing was very reasonable and shipment was very quick. Easy to do business with, recommend Hannah products, quality and service.

Best Multimeter yet!

I've gone through a lot of testing meters. As a Water Professional, accurate testing is critical to aprizing ones water to determine filtration needs. This is the one you want!! pH dead on, PPM/EC true as you can get!! This IS the meter for your needs....
