The HI8424 is a compact, waterproof, portable pH/mV/temperature meter that is supplied complete with a protective carrying case, PEI plastic body pH electrode, stainless steel temperature probe, calibration buffer sachets, and cleaning solution sachets. The meter features automatic calibration at one or two points as well as Automatic Temperature Compensation (ATC) when the temperature probe is connected.
- Compact waterproof design
- Automatic Temperature Compensation (ATC)
- Automatic one or two-point calibration
The HI8424 is an economical portable pH/ mV meter. This meter uses a BNC connector for the pH electrode input allowing for a wide selection of pH and ORP electrodes to be used. A separate temperature probe is supplied to provide temperature compensated pH measurement. The HI8424 is very basic in operation with automatic calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01). The simplicity in operation and the economical price point has made the HI8424 one of the most popular meters available in the market.

Overall greood experience. I'd say 5/5 on all counts, except the website has its quirks. The item I purchased was not in stock and the mailing address I provided was not useable, but the website allowed me go through with the transaction, even with emailed invoice etc. But the AquaCave staff is on top of things... they personally reached out with an email to tell me my item was actually backordered by two weeks and that I'd need to ship to another address. They promptly cancelled the first order before my card was even charged and I placed a fresh order. They also answered the phone when I had a question and were very responsive and helpful. After all that it was super smooth sailing. The item shipped faster than expected, was packed immaculately (rare in this day and age) and I got exactly what I paid for.
