Description
Características
Chromium IV pocket meters are digital colorimeters to perform chromium tests. They are supplied with cuvettes with lids, reagent for 6 tests, battery, instructions and quick guide for use.
- Precise and simple measurements
- Direct display of the Chromium VI value on the screen.
Depending on the range:
- Low Range: 0 to 300 ppb
- High Range: 0 to 999 ppb
Funcionamiento
Our meters are portable so they can be easily carried anywhere you need. And what’s more, the one-button operation will make you get accurate results in a simple way.
Step 1: Add a sample to the cuvette (included).
Step 2: Insert the sample into the checker and press the button to zero.
Step 3: Withdraw the sample and add the reagent as indicated in the manual.
Step 4: Reinsert the sample and press the button for 3 seconds to measure the results.
Aplicaciones
HANNA checkers are small, portable, and most importantly, they provide more accurate results than typical chemical test kits. Offering improved technology, its simple design allows for easy, hassle-free measurement.
These digital photometers or test kits serve as a bridge between the very simple test kit and professional instrumentation such as a calibratable photometer.
