Hanna Instruments HI 9124N Auto-Instruction pH Meter Review

Hanna Instruments HI 9124N Auto-Instruction pH Meter Feature

• Automatic calibration with five memorized buffer values, for ease of use
• Automatic temperature compensation (ATC), to eliminate the need for extra calculations
• Double-junction, gel-filled pH electrode, to prolong the life of the meter
• Waterproof pH meter, for use indoors and outdoors
• Stainless steel temperature probe with 1 m (3.3') cable, for hard-to-reach locations

The Hanna Instruments HI 9124 is a handheld waterproof pH, and temperature meter for measuring the acidity or alkalinity of a substance.

The meter features a large, easy-to-read, dual-level LCD screen, with a graphical interface that provides on-screen calibration instructions. Temperature compensation and pH calibration are automatic, with five memorized buffer values (pH 4.01, 6.86, 7.01, 9.18 and 10.01).

The HI 9124 has a range of -2.00 to16.00 pH (+ or - 0.01) with a resolution of 0.01 pH. Temperature range is -20.0 to 120.0 degrees C/-4.0 degrees F to 248.0 degrees F (+ or - 0.4 degrees C /+ or - 0.8 degrees F) with a resolution of 0.1 degrees C/0.1 degrees F. Input impedance is 1012 Ohm, and the meter operates using four 1.5V AAA batteries (sold separately).

pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.

Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of their products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
