Digital pH/mV Data Logger for Field Technicians

The AZ-9661 is a handheld meter that measures pH, temperature and millivolt values in a single device. It suits electricians, water-quality technicians and laboratory staff who need portable data capture. The meter stores up to 4000 automatic readings or 99 manual entries for later review.

Programmable Automatic Recording up to 4000 Points

The defining specification is the programmable auto-logging function that captures up to 4000 time-stamped records without user intervention. Sampling intervals are set on the meter or uploaded from a PC via the included cable and software. This capacity covers extended monitoring sessions that single-point or manual modes cannot.

PC Connectivity with Tripod Mount for Stable Logging

A serial cable and software CD link the meter to a computer for data download and header uploads. The built-in tripod receptacle lets the unit stand unattended during long automatic runs, reducing cable strain on the probe. Power comes from four AAA cells or an optional 9 V adaptor; the backlit 26 × 45 mm dot-matrix LCD remains readable in low light.
