Ordering from Hanna is easy and since I have the full line of testors and if I have questions as a retailer I can help others.

I am very impressed with my Hanna master checker. Shipping was not the fastest but everything came as advertised. The Calcium test is either not accurate or I am doing something wrong.

Quick response and shipping. Really excellent hand held turbidity meter. With everything needed in the kit for calibrating the instrument. Vey good price point for such good equipment.

fast shipment

It was on point
