When HANNA instruments introduced its first version of the pHep (pH electronic paper) in 1986, it immediately revolutionized the standard in pH measurement. pHep`s ease-of-use in combination with its affordability made it possible for non-technical and technical personnel alike to measure pH on the spot, accurately and inexpensively throughout a variety of industries. Since its introduction, over 1 million pHeps have gone to satisfied customers around the world.

We at HANNA instruments have always valued the comments and suggestions coming from our customers. For this series, we have included all of the features you have asked for and more! The pHep 4 and pHep 5 include features such as a dual-level LCD, battery level indicator, replaceable pH electrode cartridge, instability indicator, automatic shut-off and automatic calibration all in a floating, waterproof casing.

Hanna PH Tester by JEROME CORDEIRO

Comments: I like the tester and it is very accurate, however, when it arrived, the calibration was off. The instrument was shipped without a means to calibrate it. I later found a packet of buffer solution to calibrate. One must hold it in solution for about 30 seconds to get a stable reading.Don't forget to purchase the calibration packets and the cleaning solution during the initial purchase. Instructions are minimal at best. No more test strips for me.
Yes, I would recommend this product to my friends.

Comments: This thing is pretty nice!! Do get some extra calibration buffers for peace of mind. Waterproof so I can just clip it on my overflow and with .05 accuracy you can watch you PH slowly climp up while kalkwasser dosing. Temperature gauge is nice too. The only bad thing is , it proved my coralife didital thermometer was off by 3.9 deg. Time for a better thermometer!! Those things are junk!
Yes, I would recommend this product to my friends.
