Formaldehyde analyzer product introduction and application

1, check the battery

Before use, check the condition of the rechargeable battery. Set the function switch (FUNCTION) to BAT, TEST “A”. If the battery is in good condition, display 100 or more on the LCD panel (ignore any decimal point when checking the battery) and use it for 12 hours continuously.

Turn the FUNCTION switch to BAT.TEST "B". This location tests the analyzer amplifier battery. This set of alkaline batteries powers the sensor and stays ready whether the analyzer is on or off. For safety reasons, it is best to replace the battery before the LCD shows below 100.

2. Alarm setting

Usually the factory sets the alarm to 50% of the full scale and the alarm can be reset by the following methods.

(1) Set the function switch (FUNCTION) to zero (ZERO). Turn the "zero" knob to make the LCD display the required alarm concentration value.

(2) Turn the alarm setting (ALARMSET) clockwise until the "alarm lamp flashes." If the alarm value is already active, turn the ALARMSET button counterclockwise until the alarm value does not move, and then turn clockwise to return the alarm light just flashing.

3, the instrument zero

The instrument often requires on-site zeroing prior to use. The zero adjustment is performed in SAMPLE mode. The sample space uses a Type C12 filter to filter the gas to zero.

4, sampling gas

Set the function switch (FUNCTION) to the SAMPLE position to activate the pump and place the analyzer in the sample gas mode.

After the instrument is stable, the concentration of formaldehyde gas is displayed, and the sample flow rate is approximately 1 litre/minute.

Applications

The formaldehyde analyzer has a well-sealed titration cell. All the seals are produced with a highly stable mold, so that the titration process is completely separated from the outside world. The automatic liquid discharge system can automatically replace the solvent or remove the waste liquid, avoiding chemical reagents. Contact with the human body.

Formaldehyde analyzer is widely used in industry, agriculture, medicine, scientific research institutions and other industries. The content of free water in tobacco, paper, food, tea, feed, grain, chemical raw materials, pharmaceutical raw materials, textile raw materials, etc. can be tested and data printed.

Formaldehyde measurement technology Application of new data communication technology and computer-operated operating system-based control software development The new-generation moisture analyzer can be adjusted according to the sample's titration accuracy and titration speed. It is convenient, fast, and accurate to test the moisture content of different ranges; The environmental conditions of the experiment can be set with “automatic” or “manual” drift value background subtraction to ensure that the analysis results are more accurate; “Automatic” or “Manual” endpoint recognition can be selected according to different Karl Fischer reagent labels.

High-precision standard piston burettes and anti-diffusion titration heads ensure high-precision potentiometric titrations. The push-in design of the burette allows it to be easily and quickly replaced at any time. The combination of titration reaction bottle modules greatly reduces the cost of reaction vessels and other consumables, making the moisture analyzer consumables extremely low cost.
