based pH and temperature meter.
Main features include: extended pH and
temperature ranges; waterproof and com-
pact casing; large dual-line display; low
battery detection; automatic pH calibration
at one or two points with two memorized
buffer sets (standard or NIST); selectable
temperature unit (°C or °F).
The pH electrode has a built-in tempera-
ture sensor for simultaneous pH and tem-
perature readings, and also contains a mini
amplifier to render measurements imper-
vious to noise and electrical interferences.
Each meter is supplied complete with
