Hanna Instruments HI 207 Educational pH Meter without Internal Ministirrer Feature
- Automatic one- or two-point calibration with two sets of memorized buffers for ease of use
- Automatic temperature compensation (ATC) to eliminate additional calculations
- Large LCD screen for readability
- Hold function to freeze display and record results
- Replaceable probe to prolong life of the meter
The HI 207 is a pH and temperature meter with a built-in beaker and electrode holder for minimizing use of space.
The meter features a large LCD screen, automatic temperature compensation (ATC), and a hold function to freeze and record results. Calibration is automatic at one or two points, with two sets of memorized buffers (4.01, 7.01, 10.01 or 4.01, 6.86, 9.18).
pH range is -2.00 to 16.00 (+ or - 0.02pH) with a resolution of 0.01 pH. Temperature range is - 5.0 to 105.0 degrees C (23.0 to 221.0 degrees F) + or - 0.5 degrees C (up to 60 degrees C), + or - 1 degrees C (up to 105 degrees C); + or - 1 degrees F (up to 140 degrees), + or - 2 degrees F (up to 221 degrees F). The device operates on one 9V battery or a 12VDC adapter for periods of extended use. Dimensions are 190 x 105 x 50 mm (7.5 x 4.1 x 1.9”).
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 the world’s first pH electrode with a built-in temperature sensor, electronic pocket-sized pH tester, and replaceable electrode pH pocket tester. To ensure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
