Designed for the modern lab, this karl fischer titrator is the perfect fit for your testing environment.
Compact design will save space in the lab without compromising your results.
Durable heat and chemical resistant body.
Sealed solvent system helps to keep water out of the system, while giving you minimal exposure to the reagents.
FEATURES:
~ Small footprint, requires minimal bench space
~ Casing made with strong, chemically resistant plastic
~ Powerful built-in algorithms for termination criteria based on fixed mV endpoint or absolute/relative drift
~ Sample analysis averaging and statistical data
~ Minimized water vapor entry with the sealed solvent system
~ Balance interface for automatic weighing
~ Support for 100 titration methods
~ User-customizable reports
~ Clearly displayed warning and error messages
TITRATOR CAPABILITIES:
Dynamic Titrant Dosing - The titration speed feature allows for timely and accurate titration results by relating the amount of iodine generated to the mV response from the Karl Fischer reaction.
Drift Rate Compensation - The HI934 automatically adjusts the titration calculation to account for the effects of any ambient humidity entering the titration cell. This provides a more accurate result by correcting for water not present in the actual sample.
Titration Results Averaging - Successive results from a titration method may be averaged with recording of the standard deviation.
Selectable Endpoint Criteria - The HI934 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates.
Multistage Cell Preparation - A pre-titration stage eliminates residual water present in the solvent and the cell, providing a reliable baseline start to analysis. Standby mode then keeps the solvent dry between titrations and when the titrator is not in use.
