Product Description
When pH data has to stand up to an audit, the meter needs precision and records to match. The OHAUS Aquasearcher AB41PH delivers 0.001 pH resolution with ±0.002 pH accuracy and can assist with 21 CFR Part 11 compliance.
This listing is for OHAUS item number 30589831: Aquasearcher pH Bench Meter a-AB41PH -F, with ST410 Electrode, -2.000-20.000 pH, ±0.002 pH. Its range spans -2.000 to 20.000 pH, ±2000 mV and -10 to 125 °C. i-Steward guidance, three endpoint modes, password management and a log of the ten most recent calibrations support regulated work, with GLP/GMP output and a real-time clock over RS232 and USB. The meter stores 1,000 results, uses a capacitive touch keypad and runs on the included AC adapter; the -B model is meter only and the -F model includes an ST410 electrode. LIGHT LABS supplies the OHAUS line with knowledgeable support from our Englewood, Colorado team.
