Hanna HI 904 Coulometric Karl Fischer Titrator

汉娜你好904费歇尔电量滴定仪(without diaphragm) is an automatic titration system for the measurement of trace amounts of water in various samples ranging from 1 ppm to 5%. This powerful titrator effectively monitors the Karl Fischer reaction, detects the endpoint, and performs all necessary calculations and graphing. Choose from included methods or develop a custom method for almost any application or sample type. Methods (standard or user) and reports can be transferred between titrator and PC via USB interface by using the Hanna PC software. Software updates can be performed using a USB flash drive.

Features and benefits:

1) Precision dosing system by generator electrode

- 400 mA pulsed current

- Fritless (no diaphragm) generator uses one easy-to-replace Karl Fischer reagent and has a lower and more stable drift rate. Offers easier cleaning of generator cell.

2) Molecular sieve desiccant

- Prevents the ingress of ambient humidity into the sealed solvent system while maintaining full titrator functionality

- Regenerated at 300°C

3) Sealed cell

- Generator electrode

- Dual pin bivoltammetric platinum sensing electrode

- Molecular sieve desiccant cartridge

- Replaceable septum for liquid sampling port

- Accessory port

4) Built-in stirrer

- Automatic, integrated magnetic stirrer adjustable from 200-2000 RPM

- Optical feedback for automatic speed control

5) Sealed solvent system

- Change to fresh reagent in a matter of seconds without opening titration vessel

- Minimizes exposure to ambient humidity

- PTFE tubing is resistant to harsh KF chemicals

- Sealed tube holder to collect PTFE tube after exchanging reagent

6) PTFE bottle cap

- Caps fit any GL45-threaded bottle

- Chemically-resistant caps and fittings

- Removable desiccant cartridges
