The Hanna HI 4421 is a professional meter with extensive capabilities in measuring and interpreting DO measurements as BOD, OUR and SOUR paradigms. Temperature and atmospheric pressure measurements are possible with this meter.
Four viewing modes are available on the display screen: basic information, GLP information, Graph and Log History.
• Large color display with 4 viewing modes
• Millesimal measuring resolution
• Exclusive Calibration CheckTM
• Automatic or standard 1 or 2 point calibration
• Polarographic probe with built-in temperature sensor
• GLP compliance
• Opto-isolated USB and RS232 connections
There are three selectable logging modes: automatic logging - with an adjustable sampling period, Log-On-Demand (manual logging) and AutoHold logging (DO only). During DO measurements, the auto-hold feature will freeze and display the current reading. HI 4421 will store up to 100 logging lots for automatic or manual modes, up to 200 OUR and SOUR reports and up to 200 BOD method information entries. The user may also choose online or offline graphing. And all data can be downloaded to a PC via RS232 or USB interface.
HI 4421 is supplied with power adapter, instruction manual, HI 76408 DO probe, HI 7040L zero oxygen solution, HI 7041S electrolyte solution, HI 76407A/P membrane caps (2pcs), HI 76404N electrode holder and quick reference card.
