Product catalog summary

Overview: HANNA's research-grade bench meters are designed for laboratory use, offering a range of models to measure pH, pH/ISE, conductivity, and dissolved oxygen. These instruments feature a 240 x 320 dot-matrix color display, on-screen help, simultaneous graphing, language selection, and custom configuration.

Specifications:

pH Meters (HI 4221, HI 4222, HI 4521, HI 4522): Range from -2.000 to 20.000 pH with resolutions of 0.1, 0.01, and 0.001 pH. Accuracy is ±0.1 pH, ±0.01 pH, and ±0.002 pH ±1 LSD. Calibration is automatic with up to 5-point calibration and 8 standard buffers.
ISE Meters: Range from 1 x 10^-7 to 9.99 x 10¹⁰ concentration with resolutions of 1, 0.1, 0.01, and 0.001 concentration. Accuracy is ±0.5% for monovalent ions and ±1% for divalent ions.
Conductivity Meters (HI 4321, HI 4521, HI 4522): Range from 0.000 to 9.999 μS/cm to 1000 mS/cm with resolutions of 0.001 μS/cm to 1 mS/cm. Accuracy is ±1% of reading (±0.01 μS/cm).
Dissolved Oxygen Meters (HI 4421): Range from 0.00 to 90.00 ppm and 0.0 to 600.0% saturation. Accuracy is ±1.5% of reading ±1 digit.

Features:

All models include USB and RS232 ports for PC connectivity, logging, graphing, and GLP.
Temperature compensation is available for pH and EC measurements, with automatic or manual settings.
Logging capabilities include recording up to 100 lots with 10,000 records per lot.
