Product Description

All you need in a portable pH meter

Robust splashproof casing
Clear LCD display with low battery indicator
Keyboard sealed against water & dirt
HOLD function freezes readings for ease of recording
Calibration, temperature compensation and buffer recognition are all automatic
Three standard buffer values
Calibration tags on LCD
Auto shut-of

Inexpensive and easy to use

One of the most popular pH meters on the market, this splashproof, portable meter delivers fast, accurate pH, ORP and temperature measurements.

Not only does it offer a 0.01 pH resolution across the pH scale, but it is also easy to use without constant reference to an instruction manual.
Calibration is automatic at one or two points with three memorised buffer values – pH 4.01, 7.01, 10.01.

Once the instrument has been calibrated, the buffer values used during calibration are displayed with tags on the display screen.
This keeps users informed of the current calibration and helps to avoid taking measurements that are out of range.

Supplied with:

HI 1230B pH electrode

HI 7662 temperature probe

HI 70004 pH 4.01 buffer solution sachets

HI 70007 pH 7.01 buffer solution sachets

HI 700661 electrode cleaning solution sachets x 2

Battery, protective case and instructions
